Whether benzoyl peroxide and glycolic acid can be combined
In recent years, doctors have studied skin care methods. Among them, benzoyl peroxide and glycolic acid (Glycolic Acid) have attracted much attention in the field of skin care. However, whether the two can be used together is really a matter of concern to everyone.

First mentioned oxybenzoyl, which has strong oxidative properties, can be antibacterial and anti-inflammatory in the skin, and is often a good medicine for acne. It can break the cell wall of Propionibacterium acne, making it difficult to survive and multiply. And it can promote the shedding of the stratum corneum, make the pores unobstructed, and prevent clogging and acne.

Besides glycolic acid, it belongs to α-hydroxy acid and has excellent exfoliation effect. It can loosen the connection between keratinocytes, make old waste keratin easy to fall off, rejuvenate the surface of the skin, and make the skin delicate and smooth. And it can promote the synthesis of collagen in the dermis and increase skin elasticity.

As for the feasibility of combining the two, there are really complications. Peroxybenzoyl has strong oxidation, and glycolic acid has a certain activity. When the two meet, or react chemically, the ingredients are inactivated and the skin care effect is damaged. If the peroxide bond of peroxybenzoyl or react with some groups of glycolic acid, its antibacterial and exfoliation power is weakened.

From the perspective of skin tolerance, the use of both alone can cause skin irritation, such as redness, tingling, desquamation, etc. If used in combination, the irritation is superimposed, and the skin may be unbearable. Especially sensitive skin is more prone to discomfort.

However, studies have also shown that if the usage and dosage are appropriate, the combination of the two may have a synergistic effect. If used in time-sharing, use peroxybenzoyl for antibacterial during the day, and glycolic acid at night to rejuvenate the skin; or use it in combination at low concentrations to gradually increase skin tolerance. However, this should be done under the guidance of professionals.

In short, the combination of peroxybenzoyl and glycolic acid should be used with caution. Before use, it is advisable to consult a professional dermatologist or beautician in detail, weigh the pros and cons according to your own skin type, skin problems and other factors, and determine a reasonable plan to achieve the best effect of skin care and avoid adverse reactions.
