On the difference between AHA and glycolic acid
The difference between AHA and glycolic acid
is a general term for a class of organic acids, which are diverse and have considerable potential in the field of skin care. Although glycolic acid is also an organic acid, it is a member of the AHA family. There are similarities and differences between the two.

First of all, it is the same. Both AHA and glycolic acid have the effect of exfoliating. It can loosen the connection between keratinocytes, make the aging stratum corneum easy to fall off, and make the skin surface smoother and more delicate. And both can stimulate the metabolism of the skin, promote the synthesis of collagen and hyaluronic acid, help improve skin elasticity, reduce wrinkles, and achieve the purpose of anti-aging.

However, they are also different. In terms of molecular structure, AHA covers a variety of organic acids with diverse molecular structures. Glycolic acid is the simplest AHA in structure, and its molecules contain only one carboxyl group and one hydroxyl group, which is relatively single. The difference in this structure makes its permeability different. Glycolic acid has strong permeability due to its small molecule, and can penetrate more quickly into the surface of the skin to exert its effect. Some members of AHA, due to their complex structure, penetrate slightly slower.

Furthermore, the effect of effect is different. Glycolic acid has a significant effect on improving rough, dull and shallow skin pigmentation due to its strong permeability. The overall effect of AHA is more diverse. In addition to the above effects, some AHA is also effective in moisturizing and regulating skin oil secretion.

In addition, there are differences in irritation. Glycolic acid is highly irritating to the skin due to its fast penetration. If used improperly, it is easy to cause skin redness, tingling and other discomfort. In the AHA family, some mild AHA are relatively less irritating and more suitable for people with sensitive skin.

Therefore, when taking care of the skin, you should carefully choose products containing AHA or glycolic acid according to your own skin characteristics to achieve the desired effect and ensure skin health.
