Research on the whitening effect of ordinary glycolic acid
The color of the skin is important to everyone. There are many opinions on the method of whitening. Today, it is impossible to explore the whitening effect of ordinary glycolic acid on the skin.

Ordinary glycolic acid, its sexual activity. The reason for its action on the skin is that its molecules are tiny and can penetrate deep into the stratum corneum of the skin. The stratum corneum is the outermost barrier of the skin. Glycolic acid can loosen the connection between keratinocytes and accelerate the shedding of old keratinocytes. During this process, the surface of the skin can be renewed, and the skin tone may be brightened due to it.

However, its whitening power is not achieved overnight. The formation of skin pigment is derived from the production of melanin by melanocytes. Through a series of complex processes, melanin is transported to keratinocytes, resulting in deeper skin tone. Although glycolic acid can promote keratin renewal, it is still necessary to study the key links of melanogenesis, such as the activity of tyrosinase.

Studies have shown that appropriate concentrations of glycolic acid may inhibit the activity of tyrosinase to a certain extent and reduce melanogenesis. However, if the concentration is not appropriate, it will not only fail to whiten, but also cause skin damage. In mild cases, redness, itching, severe cases or inflammation are counterproductive.

And individual skin differences are quite large. Different skin types, such as dry, oily, and sensitive skin, have different tolerances to glycolic acid. Dry skin is inherently dehydrated, and high concentrations of glycolic acid may make it drier; sensitive skin, or intolerance to glycolic acid, is prone to allergic reactions.

Therefore, the whitening effect of ordinary glycolic acid cannot be generalized. It is necessary to use it in an appropriate concentration and manner according to the individual skin type, and in conjunction with sunscreen and other measures, it is expected to have a whitening effect, otherwise it may be dangerous for the skin. Doctors and beauty lovers should be treated with caution and should not be blindly trusted or used.
