I don t know the whitening principle , it is also white in tossing, what are the methods of whiteni

I think the most important thing to whiten is hydration and sun protection, hydration is the foundation, sun protection is the key, and then eat food with whitening effect. Whitening is a slow process, it must be adhered to for a long time, healthy whitening, do not use some high-hormone whitening products, although the effect is significant, but it is not good.

The first thing is to hydrate. Hydration is the foundation, whitening, sunscreen, etc. are done on the basis of hydration and moisturizing. In life, it will lead to the loss of water in the body due to various reasons.

For example, the dry weather climate in autumn and winter, and the loss of water caused by strong winds or high temperatures. And as people age, people's metabolism is getting weaker and weaker, which in turn leads to a weakening of hydration ability, resulting in a series of problems such as the skin's water and oil balance. Therefore, we should always pay attention to hydration.

The second is to do a good job of sun protection. Many people think that sunscreen only needs to be used in the summer, because the summer sun is the hottest, in fact, we should use it all year round, because as long as we are outdoors, we will be exposed to ultraviolet radiation. So, some people may say that I am an office worker in the office, I am in the office every day, and I basically do not spend time outdoors, so I should not need to.

In fact, for office personnel, they should also insist on sunscreen, because the radiation of computer screens is also very strong. In addition to the use of sunscreen, when there is sun, we should also wear sunhats, sunglasses, etc., and we can also use a sun umbrella to avoid ultraviolet radiation as much as possible.

In addition to this, you can also eat more foods that have a whitening effect. For example, cabbage and cauliflower can inhibit the production of melanin, as well as kiwifruit, strawberries, tomatoes, oranges, etc., which contain a lot of vitamin C, which can also effectively whiten and help reduce melanin. Whitening is a long-term process, and the results cannot be immediate, if you can stick to it all the time, I believe it will be effective.

It is best not to use some whitening products with immediate whitening effect, this general hormone content is large and not good for the body.

Whitening daily sunscreen, as well as drug methods, you can use hydroquinone cream, hydroquinone cream can reduce pigment and whiten, but it is not recommended to rub hydroquinone cream on a large area.

The most important thing is hydration and sun protection, hydration is the foundation, and then eating food with whitening effect.

I think the most important thing to whiten is hydration and sun protection, hydration is the foundation, and sun protection is the key. Go to bed early and wake up early.

Drink plenty of lemonade, it's the most natural way I know.

What are the whitening methods? Pearl powder to do **.

First of all, you have to understand your skin type, as well as what you eat, and carefully calculate your intake.

1. The principle of melanin production.

How to maintain the best health and whitening is a matter of great concern, and the development of skin care products with high safety and expected whitening effects has always been the dream of cosmetic formulators.

Skin color is largely determined by the production, migration, and distribution of melanin. At present, the research on whitening and freckle removal focuses on tyrosinase, and the research on its activation and inhibition mechanism has been relatively systematic and in-depth, and the relevant theories are well known to cosmetic formulators.

Melanin is a polymer biological pigment, and the starting material for cells to "produce" melanin is tyrosine.

Tyrosine is a very common amino acid in the human body, in melanocytes, tyrosine is catalyzed by tyrosinase to generate dopa, dopa quinone is formed after dehydrogenation, and rearranged into 5,6 hydroxyindole, indole polymerizes and combines with structural proteins in melanocyte to form melanoprotein, which is what we usually call melanin.

Enzymes, also known as enzymes, are proteins synthesized by living cells that play an efficient catalytic role in their specific substrates, also known as biocatalysts. Almost all chemical reactions in living organisms are catalyzed by enzymes.

When it comes to choosing skincare products, most of us use the brand and ingredients to determine whether these products are suitable for us.

Here's a quick rundown of some of the different uses of a few ingredients:

1) Arbutin.

Arbutin is an extract of bearberry, and its chemical name is hydroquinone derivative, also known as hydroquinone derivative. If you look at products containing arbutin, you will find that arbutin is also classified, divided into - arbutin, - arbutin and deoxyarbutin. - Arbutin is the earliest and cheapest.

Arbutin has a medium effect but good stability, ** the highest. Deoxyarbutin works best but is unstable, so it is used minimally. Baihua Fang Spot Removal Cream contains 3% high concentration - arbutin, so the ingredients are really important in lightening spots.

2) Vitamin C

Vitamin C is one of the first representative additives used in whitening and freckle removal products. It has two main effects, one is to reduce dark melanin to light-colored melanin, and the other is to inhibit the production of melanin by intermediates. Vitamin C is very safe, but it is very stable and can quickly become inactive if left unprotected.

3) Licorice extract (licorice flavonoids).

Extracted from the root of licorice, the oil-soluble part of licorice extract can inhibit the activity of tyrosinase, water-soluble glycyrrhizate, has a mild anti-inflammatory effect, and is generally added to post-sun care products to eliminate subtle inflammation after strong sun exposure. The safety profile of licorice extract is very good, and there are no reports of adverse reactions.

When whitening skincare, be sure to remember to exfoliate regularly. Be sure to massage your face every day and do exercises, not only can your metabolism improve, your skin will be rosy and translucent, and even your face lines that have been stiff for a day can be completely relaxed! The most important thing is the skincare products.

The matter of going yellow and darkening is a big change in itself! Whitening products are a must.

Whitening needs to be adjusted internally, you can't rely on cosmetics, otherwise the situation will get worse and worse, you can supplement VC with some lemonade

Melanin is the most important pigment that affects the whiteness of the skin, and inhibiting the production of melanin is naturally the most important ultimate goal of whitening products.

Whitening strategy: whitening principles, whitening ingredients, whitening products, you need to understand these dry goods.

Always feel like you're not white enough? If you don't understand these "whitening principles", no matter how much 1,000 yuan of essence you have, it's useless!

Diet, daily life, life, and genetics are all related

Whitening principle of vitamin C:

Vitamin C can inhibit tyrosinase, thereby indirectly inhibiting the formation of melanin and reducing the deposition of melanin.

Vitamin C can promote collagen formation and prevent aging wrinkles.

Vitamin C can also play an antioxidant role, prevent ultraviolet damage, remove free radicals in the body, and prevent aging. Combined with the above factors, vitamin C can play a role in whitening.

Tips: Pay attention to two points in the selection: 1 Look at the brand, choose the big brand, ***, the effect is good; 2. Look at the platform, whether the qualifications are complete, whether there is a traceability mechanism, whether it stands with consumers, and the after-sales service is guaranteed.

There are two ways to whiten, one is to pay attention to sun protection, part of which is physical sun protection, part of which is chemical sun protection, physical sun protection refers to wearing hats, sunglasses, masks, and then the whole body should also pay attention to the sun protection of long pants and long sleeves. So what about chemical sunscreen, you should pay attention to applying sunscreen with sufficient SPF value, and you can also maintain whitening by taking it internally, such as eating more fruits or foods rich in VC, etc.

Avoid going outside to sun, physical sunscreen, wear hats, umbrellas, and sun-protective clothing, although it may be hot, when the weather is too hot, make up for some sunscreen and hold an umbrella.

1.Go to bed early and get up early, have a regular schedule and don't stay up late.

2.Pay attention to sun protection.

3.Eat more fruits and vegetables.

4.Eat more collagen-rich foods. Such as pig's trotters and soybeans.

5.Keep exercising and keep smiling.

The best whitening method is to pay attention to all aspects of diet, skin care products, health is the most important.

Whitening is a headache for many girls, and in people's awareness of whiteness, the road to whitening is also very long and difficult. Some whitening methods persist for a winter, but when they enter the summer, they will be wasted, which is very sad. My ** is also relatively dark, in terms of whitening is also into countless pits, I have practiced effective methods to improve diet, more exercise and fitness, pay attention to sun protection, adhere to these for a long time, will definitely make ** brighten a lot.

The principle is to inhibit the proliferation and differentiation of melanocytes, inhibit melanin synthase, block the transport of melanin granules, accelerate the metabolism of epidermal cells, and block the production of melanin.

The mechanism of action of whitening products on the market is mainly carried out by inhibiting the proliferation and differentiation of melanocytes, inhibiting melanin synthase, blocking the transport of melanin granules, accelerating the metabolism of epidermal cells, and blocking the signal transduction pathway in the process of melanin production.

In addition, there are also whitening products that remove and reduce the negative effects of melanin formation caused by exogenous factors, such as the use of sunscreen products can reduce some of the acquired melanin caused by ultraviolet radiation, but it cannot reduce or eliminate the pigmentation that has formed.

According to research, whitening cosmetics with niacinamide as the main active ingredient have a certain effect on inflammatory pigmentation; Licorice extract whitening products have a certain effect on melasma; Vitamin C derivatives whitening cosmetics can improve photoaging while whitening**.

Therefore, the targeted selection of compliant and suitable whitening cosmetics has a certain effect on improving skin tone.

The principle of whitening products is to lighten dark spots and brighten the skin by blocking the production and dispersion of melanin. Among them, the key role is to inhibit the activity of tyrosinase and block the synthesis and accumulation of melanin. It can also promote the metabolic excretion of melanin and reduce its accumulation in **.

Common active ingredients in whitening products are vitamin C, arbutin, yeast extract, etc. Vitamin C can promote collagen synthesis and inhibit the formation of melanin. Arbutin can inhibit tyrosinase activity and prevent melaninosis.

Yeast extract can promote the metabolism and excretion of melanin and accelerate skin renewal.

In addition to using whitening products, you can also start from your daily life, such as avoiding prolonged exposure to the sun, using sunscreen products correctly, and getting enough sleep. These all help to reduce the production and build-up of melanin, resulting in a whitening effect.

It is worth noting that when using whitening products, be careful not to overuse or use them improperly, resulting in the opposite effect. It is recommended to follow the dosage and application instructions on the product manual, while paying attention to moisturizing and repairing the skin. Whitening products are only an aid to lighten dark spots and brighten the complexion, and are not a substitute for good lifestyle habits and a healthy diet.

According to the principle of action of whitening, it is mainly divided into these types:

1.Inhibits tyrosinase at the root, thereby inhibiting and reducing paramelanin production.

2.Antioxidant decanning jujube is reduced to reduce dopa synthesis of dopaquinone, thereby reducing melanin production.

3.Inhibits the production of melanin and transmits it to keratinocytes in the epidermis.

4.Accelerates the renewal of epidermal cells and promotes the exfoliation of the stratum corneum.

Controlling melanin production? Reduces UV exposure** isolation.

The principle of whitening is to reduce the production of melanin and improve the external skin texture by regulating qi and blood from within.

The general whitening method is to eat more foods with high VC and V. This can block the production of melanin, such as eating more vegetables such as tomatoes, cucumbers, green peppers, broccoli, and more fruits such as apples and kiwifruit. The amount of melanin produced is also related to endocrine disorders and sun exposure, so you should also pay attention to avoid direct exposure to sunlight during labor.
