The secret about whitening
“Arbutin”, have you ever heard of it? It is one of the most famous whitening cosmetics raw materials. It can help female friends to realize their dream of whitening and removing beverage; is it amazing? If you are interested, just come to acknowledge it known as the legendary beauty in the twenty-first Century.
Arbutin is also known as Arbutin, bearberry leaf saponins, phenolic glycosides or bayberry bear fruit glycosides.
It is White needle crystal or powder. Arbutin is a natural active substances
derived from the set of "green plants, safe and reliable" and
"efficient decolorizing" three harmonious unity in one of the skin
bleaching component. it can quickly penetrate into skin ,not affecting cell proliferation
in the concentration at the same time and can effectively inhibit the activity
of tyrosinase in the skin, blocking the formation of melanin, directly through
its own binding and tyrosine enzyme, accelerating the melanin decomposition and
excretion, thus reducing the skin pigment deposition, eliminating stains and
freckles, but will not produce toxicity, irritation, sensitization and Other side effects on melanoma cells, at the same time it also plays bactericidal,
anti-inflammatory role.

Its biggest feature is no toxicity, irritation, sensitization and Other side effects,not producing harmful substances to skin because of ultraviolet radiation and can be a good fit with cosmetic ingredients。At the same time, Arbutin also can moisturize the skin and promote wound healing, antiseptic and anti-inflammatory effects synergy. It is the most popular as a safe and effective whitening material and the ideal material to whitening freckle in twenty-first century.
Whitening bleaching principle
1)Whitening mechanism
Melanin is produced by melanocytes in the epidermis. When the ultraviolet light penetrated the skin, melanin plays the role of ultraviolet absorption and reflection.
Under the protection of melanoma, basal cell can avoid being injured, and prevent cell from aging and mutation, making the basal cells divide and reproduce normally.
It can give you the formation of healthy, full of elasticity of the skin. If melanin synthesis ability is reduced, the skin becomes sensitive.
Therefore, a good whitening product should protect melanoma cells from being damaged and can effectively inhibit the production of melanin.
Arbutin can effectively inhibit mammalian tyrosinase
activity, without affecting the expression of tyrosinase, the growth of normal
cells and no damage to the melanocytes, it will not produce hydroquinone during suppression and is an efficient, safe tyrosinase inhibitor.
2)The decolorization effect
With the development of biological science and technology making a spurt of progress,
in the early ninety's, Japan's Shiseido and Other companies in the world firstly
develop the biological whitening cosmetics of containing Arbutin. Some American hospitals use the Arbutin for clinical treatment of black pigmentation serious patients, the effect of removing beverage is good, the effective rate is up to 90%, and there is no toxicity, irritation and sensitization. Since then, the cosmetics company number of using Arbutin whitening is increasing.Especially recent years, the Skin care formulations which added in Arbutin appear continuously. Foreign clinical trials proved that the Arbutin has the security and stability of ultraviolet radiation, not only can be very fruitful for inhibiting melanin, but also has good compatibility with Other skin care ingredients, it can make the whitening, moisturizing, softening, wrinkle, anti-inflammatory and Other effects work better.

The difference betweenα- Arbutin and β- Arbutin
Arbutin can be divided into two Species that alpha Arbutin and beta Arbutin, Although both of them have the whitening effect, the whitening effect of alpha Arbutin is ten times of the beta Arbutin’s in contrast. α- Arbutin has overcome the weakness that is not easy to maintain steady state on the surface of the skin forβ- Arbutin and it can close the " black pigment factory" which is already open, avoiding excessive production of melanin. At the same time, it can promote the the new supersedes the old and help the skin successfully remove dead skin cells, leading to the natural exfoliation. Something which is more magical is that alpha Arbutin can repair the UV-induced damage and get the transparent feeling for skin back.
