On the effect of glycolic acid on the dullness of the knee
The color of the husband's skin is related to the beauty of the appearance. The dullness of the knee often disturbs everyone. Since modern times, there have been many investigations into the use of glycolic acid in skin care. Today, let's discuss the effect of glycolic acid on the dullness of the knee.

Glycolic acid belongs to the class of fruit acids, with small molecules and strong permeability. It can loosen the connection between keratinocytes in the stratum corneum of the skin, promote the exfoliation of old keratin, and accelerate the renewal of the skin surface. The knee is prone to dullness due to daily friction and exfoliation. The exfoliating effect of glycolic acid can gradually remove the accumulated old keratin, making the skin surface smooth and the color also improved.

Furthermore, glycolic acid can stimulate the synthesis of collagen in the dermis. Collagen, the support structure of the skin, is related to skin elasticity and luster. In the dull part of the knee, stimulated by glycolic acid, collagen is reborn, the skin can be tightened, the luster reappears, and the dullness gradually fades.

When using glycolic acid, you need to be careful. It is irritating to a certain extent. If the concentration is too high, used too frequently, or causes skin discomfort, such as redness, tingling, peeling, etc. Therefore, when using it for the first time, it is advisable to choose a low-concentration product and try it on a small area of skin to observe its reaction. If there is no abnormality, then gradually expand the scope of use. When using it, you should also do a good job of sun protection to prevent the skin from being more sensitive to ultraviolet rays due to irritation, resulting in increased pigmentation.

In summary, glycolic acid does have the potential to improve knee dullness. However, reasonable use, your mileage may vary, can achieve the desired effect, help the skin restore even and shiny.
