Produt Introduction
α- Arbutin is a new whitening material. α- Arbutin can be rapidly absorbed by skin, selectively inhibit tyrosinase activity, thus blocking the synthesis of melanin, but it does not affect the normal growth of epidermal cells, nor inhibit the expression of tyrosinase itself. At the same time, α- Arbutin can also promote the decomposition and excretion of melanin, thus avoiding the deposition of skin pigment, and eliminating freckles and freckles. α- The action process of arbutin will not produce hydroquinone, nor will it produce toxicity and irritation to skin, as well as side effects such as allergy. These characteristics determine α- Arbutin can be used as the safest and most effective raw material for skin whitening and stain removal. α- Arbutin can disinfect and moisten skin, resist allergy and help heal damaged skin. These characteristics make α- Arbutin can be widely used in cosmetics.
Characterstic
1.Quickly whiten&brighten the skin, and the whitening effect is stronger than β- Arbutin, suitable for all skin.
2.Effectively fade spots (senile spots, liver spots, pigmentation after sun exposure, etc.).
3.Protect skin and reduce skin damage caused by ultraviolet.
4.Safe, low consumption and low cost.
5.It has good stability and is not affected by temperature and light in the formula.
Effect
1. Whitening and depigmentation
Tyrosine is the raw material for the formation of melanin. Tyrosinase is the main rate-limiting enzyme for the conversion of tyrosine to melanin. Its activity determines the amount of melanin formation. That is, the higher the activity and content of tyrosinase in the body, the easier it is to form melanin.
And arbutin can produce competitive and reversible inhibition on tyrosinase, thus inhibiting the production of melanin, achieving the effect of whitening, brightening and freckle removal!
2. Sunscreen
α- Arbutin can also absorb ultraviolet rays. Some researchers will add α- The sun protection products of arbutin have been specially tested and found α- Arbutin showed ultraviolet absorption ability.
In addition, it has been verified by many scientific research experiments that in terms of anti-inflammatory, bacteriostatic and antioxidant, α- Arbutin also showed some efficacy.
