Where is melanin found in which products? Melanin in food. Healthy lifestyle

The substance melanin is one of the natural means of protecting the skin from intense exposure to sunlight. During normal functioning of the body, due to prolonged exposure to the sun, the production of this substance by the body increases, as a result of which the skin acquires a dark tint.

If the body’s production of melanin is insufficient, or if it is exposed to very bright sun for a long time, it is advisable to obtain the components of this substance from the outside. To do this, it is advisable to know which foods contain melanin.

What foods contain melanin?

It is worth noting that melanin itself is not contained in food, but is produced exclusively by the human body, using a number of substances supplied with food. The list of such substances includes, for example, the amino acid tyrosine, a number of minerals (copper) and other substances involved in the process of creating melanin.

Products containing substances that help produce melanin primarily include products of animal origin. In particular, this list includes meat products: fish, poultry (for example, turkey and chicken), eggs, and various dairy products. The latter include different varieties hard cheese and milk itself.

Also an important substance for the production of melanin is copper, which is found mainly in seafood. The highest content of this mineral is found in oysters and other marine shellfish. This mineral is also found in some organ meats, such as liver. Copper, in addition to participating in the formation of melanin, also helps to synthesize elastin, a substance that helps maintain skin elasticity.

The amino acid tyrosine, used by the body in the process of melanin synthesis, is found mainly in various products of plant origin. In particular, the most rich content This substance is observed in soybeans and some cereals and legumes (lima beans, pumpkin and sesame seeds).

In addition to those listed above, there is also an additional list of products, the consumption of which will stimulate an increase in melanin content due to the presence of tyrosine and copper in them. This list includes nuts (for example, almonds, peanuts and pine nuts) and legumes (beans of any kind). The content of these substances is also observed in a number of dark leafy vegetables. It is advisable to eat fruits such as bananas and avocados. Cereal crops are also rich in substances for the production of melanin: rice, corn, barley.

In addition to the products listed above, melanin production is also increased by decoctions and infusions of some medicinal herbs, for example, chamomile, lemon balm, hops, and motherwort.

It is worth noting that a number of products and products cause a decrease in melanin levels. When they are consumed, the level of synthesis of this substance will be reduced, regardless of the presence of other products on the menu, the level of this substance in the body will decrease. A decrease in melanin levels is caused by different kinds stimulants (, strong tea, energetic drinks), tranquilizers (sleeping pills, antidepressants), analgesics.

Problems with the spine should never be neglected. We suggest undergoing an examination and an MRI of the spine. Fast and inexpensive. More details on the website.

The eye is involved in the formation of tanning, but not everyone knows about the other functions of this pigment substance and the mechanisms of its production. This amorphous pigment is produced by special cells - melanocytes - and not only plays the role of living, natural paint, but also protects our body.

The process of melanin formation in humans is closely related to the functioning of many endocrine glands. Scientists have found that melanin synthesis is controlled by hormones synthesized in the pituitary gland with the participation of the thyroid gland, sex and steroid hormones. This is why pigmentation disorders are often observed during pregnancy or with hormonal disorders. skin and hair. In our article we will introduce you to the properties of melanin and ways to normalize its level in the body.

Melanin: what is it and where is it located?

Melanin (from the Greek word melanos - black) is a pigment substance, which is an amorphous suspension of various polymer compounds that color the tissues of animals, microorganisms, plants and fungi.

There are several types of melanins:

eumelanins (or DOPA-melanins) – black and brown;
pheomelanins – yellow;
neuromelanins.

Not all melanins are capable of affecting the human body; some of them are ballast substances. Only DOPA melanins (black and brown) are widely used by the human body.

Melanin contains the following substances:

carbon;
nitrogen;
hydrogen;
sulfur (sometimes) and other substances.

The amino acid composition of melanins has not yet been sufficiently studied. It is known that the composition of this pigment includes:

arginine;
tyrosine;
tryptophan;
cystine;
histidine;
methionine, etc.

DOPA melanins are insoluble in water, organic solvents and acids, but many of them are sensitive to alkalis. We can observe such a reaction when hair is exposed to an alkaline solution.

Melanin accumulates in the epidermis in special skin cells, melanocytes. These round-shaped cells have long processes and look like starfish. They are located under the layer of keratinocytes and there are about 1200 such cells per 1 cm 2 of skin. Each melanocyte is connected to keratinocytes by bridge-like desmosomes. In this way, a functional unit is created that ensures the flow of melanin from melanocytes into the upper layers of the skin, the iris of the eye or the cortex of the hair. The pigment comes from the openings of the melanocyte into the keratinocytes by phagocytosis, binds there to proteins and determines the color of the skin. Each epidermal-melanin unit consists of about 40 keratinocytes and one melanocyte.

It is the level of melanin in the tissues of the skin, hair and iris of the eye that determines their color. In Europeans, the upper layer of skin contains only single granules with this natural pigment, while in people of the Negroid race, the epidermis is completely filled with this substance.

Hair color is regulated by the level of melanin in the cortex. Dark pigments can penetrate even into the core of the hair and give it a dark shade, and fair-haired people have fewer granules with such pigment, they are located more superficially and smaller in size. Sometimes the melanin contained in the hair is non-granular (diffuse), and in such cases the person will have a red tint to the hair.

Eye color also depends on the depth and level of this natural pigment. If melanin is present only in the fourth and fifth layers, then the person will have blue or blue eyes. When the pigment is located in the anterior layers of the iris, the eye color is brown or yellow-brown, and when the melanin is unevenly distributed in the anterior layers, the eye color is gray or green.

Some people have a hereditary disorder of melanin synthesis called albinism. They either produce this pigment in small quantities or not at all. Such people, in addition to significant changes in appearance (almost white eyes and hair, colorless white skin, red eyes, etc.), often suffer from problems with hearing, vision and differ from ordinary people significantly weakened immune system.

When there is an excess of melanin, a person develops melanosis, which can be:

physiological - observed in those organs where melanin should be present (skin, hair, meninges, eyes);
pathological - observed in those organs where melanin is not normally found (intestines, mucous membranes, esophagus).

How is melanin synthesized?

The synthesis of this pigment is extremely complex, depends on the interaction of many factors and is regulated by the action of melanocyte-stimulating hormones (α-MSH, β-MSH and γ-MSH) produced by the pituitary gland. Alpha-melanocyte-stimulating hormone has the most pronounced effect on the process of melanin formation.

Pigment synthesis occurs in the organelles of melanocytes - melanosomes. It begins with the oxidation of tyrosine (an amino acid). As a result of this reaction, the amino acid dihydroxyphenylalanine (DOPA) is formed as a precursor of adrenaline. Subsequently, the molecules of this amino acid are oxidized and, after a series of reactions, are converted into melanin.

The pigment accumulates in the cells of the epidermis, and its amount determines the shade of the skin, eye and hair color. Under the influence of ultraviolet rays, more of this pigment is synthesized in the lower layers of the skin, and it becomes tanned.

Functions of melanin

The level of melanin in the skin determines its color.

The main function of melanin in the human body is its ability to protect the tissues of our body from exposure to ultraviolet rays and other aggressive carcinogenic factors. This pigment screens and absorbs excess rays. One part of them is transformed into heat, and the other is spent on photochemical reactions. This function of melanin prevents the malignant degeneration of cells under the influence of ultraviolet rays and ionizing radiation and reduces the accumulation of radionuclides in the body.

An interesting fact is that the pigment accumulates in the cell near its nucleus and thus protects the genetic information stored in it.

In addition, melanin and its precursors are capable of:

neutralize free radicals;
eliminate any stress that disrupts cellular balance and immunity;
accelerate many biochemical processes;
perform a transport function (only water-soluble forms of melanin);
have an adaptogenic effect;
reduce dystrophic-destructive processes in the thyroid gland, liver, hypothalamus and adrenal glands.

Summarizing all of the above properties of melanin, we can draw the following conclusion - this natural pigment is a universal protector that protects the cells of our body from the effects of chemical and physical carcinogenic and mutagenic factors. The multifunctionality of melanin has been proven by scientists from various countries and confirms the data that this substance is one of the strongest natural adaptogens.

What can cause a decrease in melanin levels and what are the signs of insufficient melanin?

The following factors may cause a decrease in the level of this natural pigment:

hormonal imbalance and endocrine diseases;
taking medications;
genetic diseases;
lack of vitamins and minerals;
deficiency of tryptophan and tyrosine;
aging;
frequent stressful situations;
insufficient amount of sunlight.

Signs of melanin deficiency may include the following external manifestations:

tendency to sunburn;
uneven tanning;
whitish skin color and its tendency to irritation;
whitish;
early gray hair;
premature appearance of wrinkles;
faded color of the iris;
symptoms of diseases associated with a lack of melanin: albinism, and others.

How can you restore your melanin levels?

To increase the level of melanin in the body, you can use a set of different methods:

introduction into the diet of foods that promote melanin synthesis;
medicines and dietary supplements that provide melanin synthesis.

It should be noted that taking any medications to increase the level of this natural pigment should always be discussed with your doctor.

Food

The process of melanin synthesis involves amino acids such as tyrosine and tryptophan. That is why, to activate the production of this natural pigment, it is advisable to introduce foods that are rich in these substances into the menu.

These include:

meat;
liver;
seafood;
fish;
almond;
avocado;
dates;
Brown rice;
beans;
bananas;
peanut.

For normal melanin synthesis, substances such as carotene, vitamins C, E and A are also necessary. They are contained in the following products:

apricots;
melons;
peaches;
grape;
dog-rose fruit;
carrot;
pumpkin;
legumes;
greens: spinach, sweet potatoes, lettuce, tomatoes;
citrus.

The process of melanin synthesis is also supported by para-amino-benzoic acid (or vitamin B10 or H1). It accumulates in the upper layers of the skin and is activated under the influence of ultraviolet radiation, ensuring sufficient pigment production.

Vitamin B10 is found in the following foods:

wholemeal bread;
oats;
liver;
eggs;
cabbage;
spinach;
mushrooms, etc.

Products containing copper and mineral salts can also be useful for normalizing the production of natural pigment:

seafood;
chocolate;
cocoa;
liver;
peanut;
hazelnuts, etc.

Magnesium is of no small importance for the normal production of melanin. It is found in the following products:

wheat bran bread;
pumpkin seeds;
sesame;
dates;
nuts: almonds, pine, walnuts, peanuts;
beans;
spinach, etc.

Replenishing melanin reserves by introducing beneficial and delicious products can be called the most the easy way normalization of its synthesis. The only caveat for this method is the need to take into account contraindications to the consumption of certain foods.

Healthy lifestyle

A balanced diet, walks in the fresh air and under the rays of the cool sun, sufficient physical activity, coping with stress and giving up bad habits - all these factors have the most positive effect on the condition and restoration of melanin balance. This is explained by the fact that a healthy lifestyle helps to normalize all biochemical reactions in the body and, therefore, has a positive effect on the process of melanin synthesis.

Medicines and dietary supplements

To stabilize the level of melanin in the skin, various dietary supplements can be used. They are made from natural raw materials containing substances that help compensate for the lack of vitamins, minerals and amino acids involved in the synthesis of this natural pigment.

Bevital-San

For this purpose the following dietary supplements can be used:

Pro Soleil – contains various vitamins, lutein, beta-carotene and antioxidants;
Inneov – contains Indian gooseberry extract, vitamins and antioxidants;
Bevital-San – contains B vitamins and beta-carotene;
Nature Tan - contains beta-carotene, selenium, vitamin E, soybean, grape and corn extracts.

To stimulate the process of melanin synthesis, these and other vitamin-mineral complexes and dietary supplements can be used. Before starting to take them, it is recommended to consult a doctor and exclude possible contraindications to taking them.

Scientists have tried to create synthetic analogues of melanocortins (hormones of the intermediate lobe of the pituitary gland involved in stimulating melanin synthesis), but these attempts have not yet been successful. The hormonal substances obtained as a result of the research disintegrated too quickly in the blood and did not have time to have the expected effect.

However, scientists were able to find an alternative to such melanocortin analogues: the drug Melanotan 2. The active component of this medicine was obtained by scientists from the University of Arizona and was developed as a means of preventing

Melanin is a natural pigment in the human body that helps color hair, eyes and skin. It also protects against exposure to ultraviolet rays. If there is not enough pigment, the skin burns in the sun, red spots and even cancerous tumors form. How to increase it? First, find out which foods contain melanin.

The main function is to protect the epidermis layer from the negative effects of ultraviolet rays. The pigment absorbs some of the carcinogens, which is why the skin does not burn, but acquires a beautiful, even tan. Some of the ultraviolet rays turn into heat, while the other is involved in photochemical processes. As a result, the cells do not degenerate into malignant ones, and the total amount of radionuclides decreases.

The pigment accumulates near the cell nucleus. This ensures the protection of genetic information.

Below is a list of additional functions of melanin.

Neutralization of free radicals.
Acceleration of biochemical processes.
Elimination of stress loads that contribute to deterioration immune system.
Support and normalization of the thyroid gland and liver.
Production of a substance that is responsible for eye and hair color. This explains why gray hair appears with age due to a lack of pigment.

List of foods containing melanin

The synthesis of melanin requires amino acids - tryptophan and tyrosine. There are special products that help produce natural pigment. This occurs due to the amino acid content.

low-fat steamed fish (which contains the substance tryptophan K);
beef, veal and chicken meat, liver;
seafood;
sunflower seeds, beans, dates and peanuts;
brown rice without oil and salt;
melon, apricots, peaches (foods rich in vitamins A and C, carotene);
rosehip tea;
dairy products;
all greens;
citrus fruits, vegetables (contain aminobenzoic acid);
grape.

Melanin in foods is extremely important. To get a lot of vitamin B10, which promotes its production, you need to eat mushrooms, brown bread and eggs. IN walnuts contains magnesium, which also increases the level of pigment in the body.

Before wondering what foods contain melanin, consult your doctor. Lack of pigment can occur as a natural aging process, which is irreversible.

A diet that enhances production

The production of melanin is influenced by factors such as avoiding stress, avoiding ultraviolet rays and bad habits, walking in the fresh air in places where the sun does not penetrate. But the main component is considered balanced diet. All factors help to avoid the occurrence age spots and freckles, even if a person has a hereditary predisposition to them.

Below is sample menu per day, which can enhance pigment production. Serving sizes and daily norm calories are determined individually, depending on weight, height and age.

Breakfast.

In the first half of the day, you need carbohydrates and fermented milk products, which contain tryptophan. Cook oatmeal in milk, add a handful of walnuts, dates and peanuts. An analogue is boiled brown rice.

Afternoon snack.

Eat 2 oranges and drink Herb tea, preferably from rosehip.

Dinner.

This meal should be the most satisfying and rich in amino acids. Steamed fish stew with vegetable stew is suitable. Or cook liver with mushrooms. For dessert, eat a banana. Remember, to produce melanin you need to eat meat or fish daily.

Snack.

Eat a grapefruit or drink a glass of carrot-apple juice.

Dinner.

Prepare steamed chicken and vegetable salad. Also eat a slice of wholemeal bread.

To speed up the results, you can also use vitamin supplements in tablets and special preparations Melanotan-2, Melatonin. Together they increase the secretion and synthesis of melanin. All additives and medications Use only after your doctor's approval.

What foods reduce melanin levels?

Ultraviolet rays are the root causes of pigment reduction. However, poor nutrition also has a strong impact.

To avoid red rashes and spots on the body, you need to know which products reduce pigment levels:

fried, salted and smoked dishes;
all types of sausages, frankfurters, sausages;
chocolate, sweets, any sweet products;
coffee and cocoa;
alcohol, cigarettes;
corn.

Avoid all high-calorie foods containing large amounts of cholesterol.

Today, there is debate about whether citrus fruits are beneficial for melanin production. Some say that such fruits slow down skin aging, and therefore the appearance of red spots. Others believe that citrus fruits cause a decrease in melanin levels. Doctors are inclined to the first theory. But try to consume oranges, lemons and strawberries in moderation. After all, such products also lead to allergic reactions.

Diet, medications and doctor's advice will help temporarily get rid of rashes and increase pigment levels.

Melanin is a natural pigment that gives human hair, skin and iris their unique and natural color.

Melanin is produced by pigment cells in the skin called melanocytes.

The main function of melanin produced by the human body is to protect the skin from ultraviolet radiation sun. Products that contain melanin-replenishing substances and microelements include foods of animal origin, cereals, nuts, vegetables and fruits.

Melanin in the human body is produced in response to the sun's harsh ultraviolet radiation, while simultaneously protecting the skin by converting the radiation into ordinary heat.

The amount of melanin in the body determines the skin's ability to resist a number of diseases, including pigmentation, sun damage, and melanoma, an aggressive form of skin cancer.

The more melanin produced by the body, the better body protected from harmful ultraviolet rays.

Thanks to sunlight, the body also produces vitaminD, protecting the skin from free radical damage and maintaining its natural moisture.

The body's ability to produce melanin depends on:

human nutrition;
surrounding ecology;
genetic factors;
a person's age - the older a person gets, the less melanin the body produces.

There are many ways to increase the production of melanin in the human body, associated with the consumption of certain food products, eliminating the effects of toxins and taking vitamin supplements.

Vegetables and fruits

Vitamins A, B, C, E, D, beta-carotenes and minerals play a vital role in the production of melanin in the human body. They also maintain healthy skin color by protecting and repairing skin cells from sun damage.

Carrot. This vegetable is rich in the yellow-orange pigment beta-carotene (provitamin A), which belongs to the group of carotenoids. naturally changing skin color.

Research shows that consuming a few extra servings of beta-carotene-rich fruits and vegetables each day may cause increased skin pigmentation.

However, consuming too many carrots can cause the development of carotenemia (excessive levels of carotenoids in the blood), which causes excessive changes in skin color.

Cabbage is also very useful when it comes to a healthy tan. It contains a huge amount of vitamin A, which prevents skin diseases and helps moisturize it. Cabbage also contains a large amount of vitamin K, which enhances tanning. Vitamin C contained in cabbage eliminates skin damage resulting from sunburn.

Bell peppers contain significant amounts of beta-carotene, which, as mentioned earlier, helps give your skin a beautiful tan.

By adding pepper to your diet, you can make your skin healthy and shiny.

Sweet potatoes (yams) contain large amounts of beta-carotene, which also gives the skin a natural and warm summer tan.

Lemon is rich in microelements, vitamin C and contains high levels vitamin A, helping the body's immune system function.

Melon. This sweet fruit is also rich in beta-carotene, which positively changes skin tone to a natural, warm color.

Guava is one of the few fruits that contains high levels of the carotenoid pigment lycopene, which acts as a natural sunscreen. This protein gives the skin a higher level of elasticity, combating wrinkles.

Peaches contain high amounts of vitamin C, beta-carotene and alpha hydroxy acid, which give the skin a rejuvenating effect.

Not only does it give your skin a warmer tone, but it also fights UV damage and visible signs of skin aging.

Pineapple, apricot and papaya. These tropical fruits contain high levels of vitamin A and C, which keep your skin looking youthful and glowing. It is advisable to eat them more often.

Brewer's yeast contains vitamins B and D, as well as minerals important for the body. Yeast increases blood circulation, providing skin cells with nutrients for better melanin production.

Brewer's yeast comes in powder form and can be used to make drinks or cocktails. In addition, yeast flakes can be sprinkled on any food.

Iron-rich foods are also important in melanin production.

Often women have a lack of iron in the body due to menstrual cycles. In this case, it is recommended to pay more attention to foods containing iron.

Dark green vegetables are excellent sources of iron, particularly spinach and kale. Bananas, tomatoes, beans and peas of all types also contain large amounts of iron.

Fruits that help the body produce melanin and give you a natural tan also include mangoes, avocados and pomegranates. The best way to get nutrients from these foods is to consume them in the form of drinks. In this case, nutrients enter the blood directly and are better distributed throughout the body without being retained in the digestive system.

You can familiarize yourself with the functions of melanin in the human body.

Food of animal origin

One of the best ways Increasing the production of melanin in the human body is to consume sufficient amounts of animal proteins.

Eating animal meat and chicken eggs helps the body produce melanin in the required quantities.

Dairy products, including milk, cottage cheese and cream cheese, contain fatty acid Omega-3 and Omega-6, improving appearance skin, reducing its peeling when tanning.

Seafood is also a great way to boost melanin production. Fatty fish and shellfish not only contain a lot of protein, they are also rich in copper and iodine - a lack of these substances in the body is known to slow down the production of melanin.

Salmon is high in Omega-3 fatty acids, which leave your skin feeling smooth and silky and provide healthy hydration, reducing redness, pimples and any skin inflammation.

Also rich in antioxidants, you can add it to food of animal origin. green tea, cleanses skin cells of toxins.

Cereals and nuts

Nuts and grain seeds have powerful anti-inflammatory properties, helping to reduce skin redness and acne.

Raw almonds are especially good for the skin, as they contain magnesium, Omega-3 fatty acids and vitamin E and, in addition to their essential beneficial properties, helps reduce stress hormone levels.

These hormones often slow down the production of melanin, resulting in gray hair.

Brazil nut is useful in cases where the skin lacks elasticity and strength, which may be due to sun damage. A handful of these nuts can provide ample amounts of selenium, a powerful antioxidant that reduces signs of skin damage.

Vegetable oils, including soybean, olive, corn and wheat germ oils, contain vitamin E, which protects cell membranes as an antioxidant.

Additional sources

If for some reason it is difficult to get the recommended amount of vitamins with regular food before sunbathing, you can take nutritional supplements, containing vitamins A, B, E and D in their composition.

If vitamins are taken as supplements, you need to make sure your body is getting enough Omega-3 and Omega-6 fatty acids to help them be fully absorbed.

Foods containing these fatty acids include bread, fruit juices and dark chocolate.

Dark chocolate is especially beneficial because it contains not only a large amount of antioxidants, but also flavonoids, which moisturize the skin and make it healthier and softer.

Conclusion

In addition to these ways to increase melanin production and keep your skin beautiful and healthy, it is important to avoid toxins and pollutants that are harmful to your skin.

Toxins not only affect the appearance of the skin, but also prematurely slow down the production of melanin in the human body.

Living in a densely populated area, it is difficult to avoid encounters with pollution.

However, in this case, it is possible to ensure that the body receives the maximum amount of foods in the normal diet that increase melanin levels.

A gradual slowdown in melanin production occurs with age, but by following simple tips, you can reduce the speed of this process and enjoy beautiful, healthy, tanned skin for a long time.

Help. People, what foods contain a lot of melanin? and got the best answer

Answer from No need la la.[guru]
Carrots and apricots are indispensable sources of beta-carotene, which promotes melanin production.
Watermelons and melons, apricots and peaches, mangoes and coconuts, as well as pumpkins and blackberries contain special active substances that help human skin produce a substance such as melanin.
It is recommended to avoid certain foods as they slow down the body's ability to produce melanin. Such products are primarily all kinds of smoked meats, especially fatty, pickled and salted foods, corn, wine, coffee, nuts, and chocolate.
You should not overuse vitamin C - despite the fact that this vitamin protects the skin from free radicals that prematurely age it, it greatly inhibits the skin’s ability to produce melanin.

Hello! Here is a selection of topics with answers to your question: Help. People, what foods contain a lot of melanin?

Answer from Midday[guru]
Let's start with the fact that with an unbalanced diet or too low calorie diet(less than 1200 kcal/day), the process of melanin production is disrupted, so do not forget to eat a balanced diet.
Under the influence of UV rays, para-amino-benzoic acid (B10) stimulates the formation of melanin. Sulfur promotes skin pigmentation.
The main precursor of melanin in the body is the amino acid tyrosine. It is logical to assume that if you increase the amount of tyrosine in the cell, the formation of melanin will become more intense. Tyrosine is found in large quantities in animal products - beef and pork liver, red meat and fish. In addition, tyrosine is found in avocados, almonds and beans.
Another precursor of melanin is tryptophan. This amino acid is found in brown rice, dates, and soy products. But, for example, bananas and peanuts contain both amino acids (tryptophan and tyrosine), therefore, these products are ideal for stimulating melanin production.
However, enzymes are required to convert tryptophan and tyrosine into melanin. The more active the enzymes are, the more melanin is synthesized. Enzymes contain copper and iron salts. Therefore, it is necessary to include in food, along with amino acids, foods containing these microelements. The greatest amount of copper is found in veal liver and oysters; pork liver, black tea, sesame, and millet are rich in iron.
But sunlight not only stimulates the production of melanin, but also has a damaging effect on the skin. To avoid negative consequences Selenium and vitamin E help with insolation. Therefore, during periods of intense exposure to ultraviolet rays, you should not neglect products containing large amounts of these elements. The largest amount of selenium is in pistachios, veal kidneys and herring, and vitamin E is in sunflower and corn oil, walnuts and hazelnuts.
Keep in mind that foods rich in carotene tend to contain large amounts of vitamin C. This, in turn, suppresses the production of melanin. But Betacarotene is a precursor to vitamin A - it promotes the production of melanin, thereby accelerating the appearance of tanning.
By the way, proteins are indispensable for skin renewal. In order for melanin to be produced uninterruptedly, which is especially important under the influence of sunlight, the daily diet should contain enough protein-rich foods.
