Can glycolic acid dilute knee melanin
There is a dull skin disease in the world, especially in the knee, and everyone seeks a way to brighten it. Today, glycolic acid has attracted much attention in the way of skin care, and everyone is suspicious: Can glycolic acid dilute knee melanin?

Glycolic acid belongs to the class of fruit acids, and its molecules are small and can penetrate deep into the stratum corneum of the skin. In the stratum corneum, if the barrier of the skin accumulates dead skin for a long time, it often causes dull skin tone. Glycolic acid can loosen the connections between keratinocytes, promote their shedding, and gradually produce new skin. This is one of its contributions. And it can stimulate the synthesis of collagen in the dermis, making the skin firm and smooth, and the skin tone will also brighten.

At the knee, the stratum corneum is thicker and melanin is easy to deposit. Glycolic acid can penetrate thick keratin with its unique properties and act on melanin. It can inhibit the activity of tyrosinase, which is the key to melanin synthesis. If the activity of the enzyme is weak, melanin will be produced less. It can also accelerate the metabolism of melanin and remove it with exfoliation.

When using glycolic acid, you should also be cautious. It is irritating to a certain extent, and those with sensitive skin may have discomfort. Therefore, when using it first, it is advisable to try it on a small area to observe the skin reaction. And the concentration and frequency of use are all exquisite. Low concentrations can be used daily; high concentrations require professional guidance and should not be used frequently.

In summary, glycolic acid does have the potential to dilute knee melanin. Those who use it should be cautious according to their own skin characteristics to achieve a whitening effect and maintain skin health.
