On the Mixing of Glycolic Acid and Vitamin C
If you want to know whether glycolic acid and vitamin C can be mixed, you need to investigate its nature and reason. Glycolic acid is a type of fruit acid, which is weakly acidic and is often used in skin care to exfoliate, promote metabolism, and rejuvenate the skin. Vitamin C, on the other hand, has strong reducing properties and is a good antioxidant product for the skin, which can help whiten and resist aging.

Looking at the chemistry of the two, the acidic environment of glycolic acid may theoretically not react violently with the chemical structure of vitamin C. However, the actual mixing is still uncertain. Vitamin C is easily oxidized in the air, especially when it encounters metal ions, and skin care products may contain trace metal impurities. Although glycolic acid can increase the absorption of nutrients by the skin, if it is mixed with vitamin C, its stability may be changed.

Experiments have shown that the proper ratio of the two is mixed, which may gain skin whitening and anti-aging effects. However, if the ratio is incorrect, it may cause skin discomfort. High concentrations of glycolic acid are already quite irritating to the skin, and then mixed with vitamin C, or reduce skin tolerance, causing allergies, redness and swelling.

Therefore, when mixing glycolic acid and vitamin C, it should be tried on a small scale first to observe the skin's reaction. And when preparing, the environment should be cleaned, avoiding metal ions interference, and its stability should be maintained. It is also necessary to choose the appropriate proportion according to your own skin type, so that you can hope to get the benefits of mixing and avoid its harm.
