"On whether glycolic acid can reduce pigmentation"
There is a thing in the world called glycolic acid, and its effect on the skin is explored by everyone. Or ask: can glycolic acid reduce pigmentation?
The cause of skin pigmentation is due to various factors that cause melanocytes to be active, and melanin production is excessive, so it changes color on the surface of the skin. And glycolic acid has unique properties.
Glycolic acid is an alpha-hydroxy acid with small molecules, which can quickly penetrate the surface of the skin. First, it can promote the renewal of stratum corneum cells. If the metabolism of the stratum corneum of the skin is not smooth, melanin is easy to accumulate. Glycolic acid makes keratinocytes shed and regenerate in an orderly manner, and melanin is evacuated accordingly, so as not to accumulate into obvious pigmentation. Second, it can inhibit the activity of tyrosinase. Tyrosinase is a key enzyme in melanogenesis, glycolic acid blocks its effect, the way of melanogenesis is limited, and pigmentation is also slow.
However, everything has advantages and disadvantages. Although glycolic acid has the ability to reduce pigmentation, it is not used properly, and there are also disadvantages. If the concentration is too high, or the skin is intolerant, it is easy to cause skin redness, tingling, desquamation and other diseases. Therefore, it is prudent to use glycolic acid to reduce pigmentation. Test sensitivity first, and choose the appropriate concentration and frequency according to the skin condition, so as to ensure skin health and reduce pigmentation.
In short, glycolic acid can be used to reduce pigmentation, but it can only be used in a scientific way to achieve the desired effect.
