Description:

The inhibitory effect of arbutin on melanin is compared with hydroquinone, kojic acid and vitamin C (L-ascorbic acid).The inhibitory effect of arbutin on tyrosinase is not as good as hydroquinone, but it is better than kojic acid and vitamin C.

The pharmacological effect of hydroquinone in the treatment of pigmented diseases is to block the process of tyrosinase catalyzing the conversion of tyrosine to dihydroxyphenylpropionic acid, thereby controlling the biosynthesis of melanin, but it does not damage melanocytes or affect the synthesis Of melanin. Hydroquinone is still the best and most effective ingredient that acts directly on whitening.
Hydroquinone has been found to have a whitening effect, coupled with the characteristics of being cheap and easy to obtain, so it is more and more widely used in freckle bleaching cosmetics. Usually people only use this kind of cosmetics on the face to achieve the purpose of diminishing dark spots and whitening skin. In recent years, it has been introduced in the literature that sitacium chloride can stabilize hydroquinone; and some externally applied drugs for the treatment of melasma Hydroquinone
