Glycolic acid is a common ingredient in many skin care products, which has the effect of improving skin texture and promoting keratin renewal. However, when using it, you must pay attention to the problems that may be caused by mixing with certain ingredients.

Bear the brunt, glycolic acid should not be mixed with strong alkali ingredients. Strong alkali will react violently with glycolic acid, changing the original chemical structure of glycolic acid, not only causing the loss of its skin care effect, but also may generate substances harmful to the skin, which in turn irritate the skin, causing redness, swelling, tingling and other uncomfortable symptoms.

Furthermore, high concentrations of vitamin C should not be mixed with glycolic acid. The two are chemically active and prone to redox reactions after mixing. This reaction not only reduces the antioxidant properties of vitamin C and the skin care effect of glycolic acid, but also may produce unstable intermediates, increasing the risk of skin allergies.

In addition, metal salts with astringent effects, such as aluminum salts, zinc salts, etc., should not be mixed with glycolic acid. The acidic environment of glycolic acid can promote reactions such as hydrolysis of metal salts, resulting in insoluble substances, which may clog pores, affect the normal respiration and metabolism of the skin, and cause frequent skin problems after long-term use.

When using skin care products containing glycolic acid, be sure to carefully check the product ingredient list and avoid mixing with the above ingredients, so as to ensure that the skin care process is safe and effective, give full play to the positive effects of glycolic acid on the skin, and achieve the ideal skin care effect.
