On the relationship between glycolic acid and melasma
There are skin diseases in the world, and melasma is troubled by everyone. The relationship between glycolic acid and melasma is worth exploring.

Glycolic acid is often used in skin care. Its mild nature and unique ability can act on the surface of the skin. Those who cover the stratum corneum of the skin are the barrier of the skin, but for various reasons, its metabolism is abnormal, and pigmentation occurs. Glycolic acid can gently exfoliate the stratum corneum, make the metabolism of the stratum corneum orderly, and make the old waste keratin on the surface of the skin fall off and the skin rejuvenate.

The cause of melasma is mostly related to endocrine, sun exposure, etc. Endocrine disorders cause imbalance in pigment metabolism, melanin is deposited locally in the skin; excessive sun exposure also stimulates melanin production. Although glycolic acid cannot directly regulate endocrine, it can improve the metabolism of the skin and help the excretion of melanin. After glycolic acid care, the metabolism of the skin accelerates, and the deposited melanin may fall off with the old waste keratin, or be decomposed and transported by the skin's own metabolic mechanism, thereby reducing the color of melasma.

And glycolic acid can promote the synthesis of collagen in the skin. Collagen is the support structure of the skin, and its abundance makes the skin plump and shiny. When collagen synthesis increases, the texture of the skin improves and the color is uniform, which is also beneficial for the relief of melasma.

However, the use of glycolic acid in the treatment of melasma also requires caution. Individuals have different skin, or those with sensitive skin, if used improperly, it will cause skin discomfort, such as redness, tingling, etc. Therefore, before use, the skin should be carefully inspected, before local trial, depending on its reaction. And the concentration and frequency of glycolic acid need to be considered. If the concentration is too high and the frequency is too high, it can damage the skin barrier.

In short, glycolic acid is indeed related to melasma, and it is reasonable to use it, or it may be a method for light spots. However, it must be used scientifically according to the characteristics of the skin in order to achieve the effect of protecting skin light spots and avoid the risk of skin damage.
