Compatibility of Mixing Glycolic Acid and Niacinamide
Recently, there have been many studies on skin care methods, and whether glycolic acid and niacinamide can be mixed and shared is also a hot topic.

Glycolic acid belongs to the fruit acid category, which has the power of rejuvenation. It can loosen the stratum corneum of the skin, make the skin smoother, and can promote the production of collagen to reduce wrinkles and improve skin quality. Niacinamide has many advantages, which can prevent the transfer of melanosomes to keratinocytes, achieve whitening and brightening effects, and can also enhance the skin barrier, regulate sebum secretion, and improve skin problems such as acne.

However, the two are mixed, so you need to be cautious. From a chemical point of view, glycolic acid is acidic, and niacinamide may undergo hydrolysis in an acidic environment to form niacin. Niacin may cause skin redness, tingling, itching and other uncomfortable symptoms, especially for people with sensitive skin, this risk is higher.

If you want to use both at the same time, you can use it at intervals. Niacinamide products can be used during the day to enhance the skin barrier, resist external damage and whiten the skin; when the skin is repaired at night, use glycolic acid products to exert its skin rejuvenation effect. And when using it for the first time, it should be tried on a small scale, and the frequency and dosage should be gradually increased according to the tolerance of the skin.

In summary, although glycolic acid and nicotinamide have good skin care effects, when mixed, it is necessary to consider the skin condition and use method carefully to ensure safe and effective skin care.
