When it comes to the mixed use of glycolic acid and benzoyl peroxide
to cause skin diseases, acne is common, and doctors often treat it with glycolic acid and benzoyl peroxide. However, whether the two can be mixed, there are different opinions, which need to be explored in detail.

Glycolic acid belongs to the class of fruit acids, and its molecules are slender and can pass between keratinocytes smoothly. It can loosen the adhesion between cells, make the old keratin fall off, and the skin surface is renewed, the skin tone is bright, and the texture is also delicate. And it can promote the synthesis of collagen in the dermis, which is very effective in anti-aging and skin rejuvenation.

Benzoyl peroxide is a good medicine for anti-acne. It can slowly release new oxygen and benzoic acid on the surface of the skin. New oxygen has strong oxidizing properties and can annihilate Propionibacterium acne, which is the main cause of acne breeding; benzoic acid can help exfoliate the keratin, make the hair follicle mouth unobstructed, oil excretion is unimpeded, and the formation of acne is also curbed.

As for whether the two can be mixed, the advantages and disadvantages need to be carefully considered. From a chemical perspective, glycolic acid is acidic, and benzoyl peroxide is easily decomposed in contact with acid, resulting in damage to stability or damage to drug efficacy. And benzoyl peroxide has strong oxidation, glycolic acid has a certain degree of reductivity, and the two meet, or biochemical reaction, resulting in adverse consequences.

According to the theory of skin tolerance, glycolic acid can cause short-term tingling and redness of the skin, and benzoyl peroxide may also cause skin irritation and dryness. Mixing the two, irritation is superimposed, and the skin may be unbearable, especially for sensitive skin.

However, if used properly, it is also beneficial. For mild acne and good skin tolerance, low-concentration glycolic acid and benzoyl peroxide can be used at intervals, which may be synergistic. First use glycolic acid to improve keratin metabolism, and then use benzoyl peroxide to sterilize and anti-inflammatory, and the treatment of acne may be more effective.

Mixing glycolic acid and benzoyl peroxide should be done with caution according to individual skin type and the severity of acne. It is advisable to consult a professional doctor before taking medication, and must not make any claims to avoid damage to the skin.
