Whitening Agent

Melanin is a protein that exists in the basal layer of everyone` s skin. The exposure to ultraviolet radiation can cause changes in melanin, generating a substance that protects the skin. Then, melanin moves through the layers of cellular metabolism and reaches the epidermis of the skin, resulting in skin problems such as pigmentation and uneven skin color.

(1) The first step of whitening is to inhibit melanin production.

Melanin is the most important type of pigment that affects skin whiteness, and inhibiting the generation of melanin is the most important ultimate goal of whitening products.

(2) The second step of whitening is to block melanin transport.

After melanin is generated within melanocytes, melanosomes are transported along the dendritic processes of melanocytes to the surrounding keratinocytes, affecting skin color.

(3)The third step of whitening, stripping.

By softening the stratum corneum, these substances accelerate the shedding of dead cells in the stratum corneum and promote the metabolism of the epidermis, so that the melanosomes entering the epidermis fall off with the rapid renewal of the epidermis during metabolism process, thereby reducing its impact on skin color.
