Analysis of the Combination of Glycolic Acid and Benzoyl Peroxide
Voglycolic acid and benzoyl peroxide are both common ingredients in the field of skin care. However, whether the two can be used together is worth studying.

Glycolic acid is an alpha-hydroxy acid with unique effects. It can loosen the connection between keratinocytes, promote the exfoliation of old waste keratin, and make the skin surface smooth and delicate. And it can stimulate the synthesis of collagen in the dermis, improve skin texture, increase its elasticity, and make the skin glow.

Benzoyl peroxide is often used to treat acne. It can slowly release new ecological oxygen and benzoic acid, has a strong oxidizing effect, can kill Propionibacterium acne, and can also reduce excessive keratinization of hair follicles and prevent acne formation.

As for whether the two can be used together, it needs to be carefully considered. Glycolic acid is acidic, while benzoyl peroxide is easy to decompose in case of acid, and its stability is affected. If the two are used together, it may cause premature decomposition of benzoyl peroxide, weakening its antibacterial and anti-acne effects. And glycolic acid thins the stratum corneum of the skin, increases skin sensitivity, and benzoyl peroxide is also irritating. The use of the two together may exacerbate the skin's irritation response, such as erythema, itching, and tingling.

However, in some specific cases, the two are not absolutely impossible to use together. If the skin is well tolerated, and under the guidance of professionals, strictly control the order and concentration of use in a timely manner, or you can try it. If you use low-concentration glycolic acid products first, after the skin gets used to it, use low-concentration benzoyl peroxide products at a certain interval.

In summary, the use of glycolic acid and benzoyl peroxide should be done with caution. When users fully understand their skin type, consult a professional dermatologist or beauty expert if necessary to ensure safety and achieve the best skin care effect.
