Glycolic acid mixed with glycolic acid is common in skin care products. However, there are all kinds of products, must not be mixed with glycolic acid, careless use, or risk damage to the skin.

The first word is alkaline products. If alkali and glycolic acid are mixed, the reaction between acid and base will be rapid. This not only greatly reduces the effect of glycolic acid, such as keratin renewal, brightening skin tone, but also generates irritating products. For example, common soap cleansing products are mostly alkaline. If used with skin care products containing glycolic acid, apply glycolic acid products after washing the face. When the alkaline ingredients left in the cleansing soap are exposed to glycolic acid, the skin will feel tingling and redness. For a long time, the skin quality will deteriorate and the barrier will be damaged.

Times and high-concentration vitamin C products. When glycolic acid coexists with high-concentration vitamin C, the stability of both is affected. Vitamin C is easily oxidized, and the presence of glycolic acid accelerates its oxidation process. Not only is the antioxidant and whitening power of vitamin C difficult to show, but also the oxidation products may be harmful to the skin. If you get up in the morning for skin care, use high-concentration vitamin C essence first, and then apply a lotion containing glycolic acid. It will not take long to see that the color of the skin care product becomes darker, and the skin may feel uncomfortable after use, such as itching and rash.

Furthermore, benzoyl peroxide should not be mixed with glycolic acid. Benzoyl peroxide is often used in anti-acne products and has strong oxidation. Mixed with glycolic acid, the chemical reaction is complicated, or irritants are generated. Both are used for the skin. For example, apply benzoyl peroxide acne cream first, and then apply a cream containing glycolic acid, which is easy to cause excessive skin irritation, redness, swelling, and peeling. Anti-acne is not a disease that adds to the skin.

Therefore, when using skin care products, it is necessary to carefully check the ingredients and avoid the mixing of glycolic acid with the above products to ensure skin health and the effect of skin care.
