Natural, Safe, and Effective,
One of the best whitening agents of this century.
Mechanisms of Skin Whitening
White and radiant skin has always been one of the gold standards for a beauty. It is well known that the color of skin is due to level of melanin and rate of blood flow in and under the skin. Color spots and skin pigmentation are directly related to melanin pigmentation.
Melanin is produced by melanocytes in top layer of the skin. It protects prickle cells and basal cells beneath from UV rays by absorbing and reflecting irradiation energy. Melanin shields basal cells from being hurt, burnt or mutated. The unharmed basal cells can then propagate and differentiate to form healthy and elastic skin. If the capability of melanin synthesis decreases, the skin will become more sensitive to UV rays. This is believed to be the reason that skin cancers occur more often in European countries than that in African countries.
Therefore, a safe and effective whitening product must not alter melanocytes while inhibiting melanin formation. α-Arbutin is exactly such a product.
How does α-Arbutin work?
Human Skin Melanin Study
The study compare the effect of α-Arbutin with that of β-Arbutin in 34 volunteers demonstrated that 1% α-Arbutin has a faster and more pronounced skin lightening effect than 7% β-Arbutin. After one month of application the melanin levels of α-Arbutin users were significantly lower than those of before the application, which meant that α-Arbutin not only inhibited the stain formation, it also helped to dissolve the pigmentation. Theses two mechanisms make α-Arbutin superior to its beta arbutin.
The L value is an index for measuring skin color. When skin color becomes lightened, L value also increases. Human Skin Melanin Study on 34 volunteers demonstrated that α-Arbutin helped inhibit the stain formation in the process of stain forming, while it obviously helped accelerate dissolve the pigmentation in the process of spontaneous regression.
