On the Compatibility of Mixing Glycolic Acid and Vitamin C
If you want to know whether glycolic acid and vitamin C can be mixed, you should investigate their chemical characteristics and interaction reasons in detail. Glycolic acid belongs to the class of fruit acids and has active chemical properties. It is often used in skin care to promote keratin renewal and increase skin luster. Vitamin C, also known as ascorbic acid, has strong reductive properties, and can resist oxidation and whitening in skin care.

Looking at the chemical structure and properties of the two, glycolic acid contains carboxyl groups and is acidic; the molecular structure of vitamin C makes it also acidic. When the two are mixed, the acidic environment may change. However, the change in acidity may not necessarily cause the two to lose their effectiveness or cause adverse reactions.

From the perspective of chemical reaction, although both have active chemistry, under normal conditions, without special catalysts or severe environments, the two are not prone to chemical reactions that cause their structures to change. For example, in aqueous solutions, the carboxyl groups of glycolic acid and the hydroxyl groups and alkenediol structures of vitamin C are not prone to direct esterification or other complex reactions.

In practical applications, many skin care formulas have also tried to combine glycolic acid with vitamin C. Some users have reported that mixed use in reasonable proportions does have a synergistic effect on skin rejuvenation, whitening and brightening. However, there are also individuals who feel uncomfortable after use due to sensitive skin or the influence of other ingredients in the product.

Overall, glycolic acid and vitamin C are compatible in most cases. However, in practical application, individual skin differences and the influence of other ingredients in the product formula must be taken into account, and the principle of moderation should be followed to prevent excessive skin irritation. In this way, the effect of both can be well used to achieve the purpose of skin care.
