Glycolic acid——a shortcut to freckle and whitening

Glycolic acid is a hydroxy acid derived from sugar cane. It is the smallest molecular weight fruit acid with a molecular weight of 76.05. This molecular weight is quite small. It is generally believed that molecules with a molecular weight above 500 are more difficult to enter the skin. It can be seen how easy it is for glycolic acid to enter the skin with such a small molecular weight, and the effect will not cause the problem of ineffectiveness due to inability to absorb.

The main function of glycolic acid is to reduce the adhesion of desmosomes in skin cells, accelerate the shedding of the epidermal stratum corneum, increase the metabolism of epidermal cells, and promote skin renewal, so it can improve roughness, dullness, pigmentation or abnormalities, and make the skin Skin tone becomes uniform and white. Therefore, glycolic acid is the most widely used ingredient in fruit acid peels.

In addition, glycolic acid can also make the dead keratinocytes around the pores fall off easily, and unblock the hair follicle tube, effectively preventing clogged pores. Therefore, for people with oily skin and those who want to improve symptoms such as acne and enlarged pores It is a very good choice.

Also, because of its small molecular weight, glycolic acid can penetrate deep into the dermis of the skin and stimulate the proliferation and rearrangement of hyaluronic acid, acid mucopolysaccharides, collagen and elastic fibers, and the skin becomes firm and elastic, with fine lines and wrinkles. Will decrease accordingly. Due to the increase of hyaluronic acid, the water retention capacity of the skin is also improved, which can solve various skin diseases caused by extremely dry skin. Therefore, dermatologists use glycolic acid to treat a variety of skin diseases, which is quite effective.

Although the effect of glycolic acid is fast and significant, you must pay attention when using it: skin test must be done before use, especially for people with sensitive skin, and it must be used in conjunction with sunscreen products to prevent newly grown skin from being sunburned by ultraviolet rays. Also note that the concentration can not be too high, preferably not more than 30%. More than 30% of glycolic acid operations are left to qualified doctors to complete.
