Melanin is generated within the melanocyte, the melanin cell exists in the base layer of the skin epidermis, so this kind of functional ingredients must penetrate into skin, reach the base layer to exert its effect, this is a difficult problem, because it is hard to through the natural barrier of corneous layer, so it is also a lot of whitening cosmetics effect not ideal of a very important reason. On the market at present commonly used inhibiting melanin whitening agent mainly arbutin and its derivatives, kojic acid and its derivatives, vitamin C and its derivatives, endothelin antagonists, licorice flavonoids, anthocyanins, as well as green tea, azalea, grape seed, rhodiola plant extracts.

So, these three kinds of whitening agent for melanin from scratch, to out of the three different stages of human body and produce different effect. Whitening are similar, and the mechanism of the spot is just the spot product has been on the splash, mainly by adding the way of stripping agent to achieve the purpose of desalination or eliminate spots. Medicated cosmetics cosmetics for special purposes (esp) in our country, because of the beautiful white product adding functional materials and similar, so, now wenzhou cosmetics OEM also monitor the whitening products as a special use cosmetics.
