Glycolic Acid Benzoyl Peroxide Application Order
On the order of use of glycolic acid and benzoyl peroxide
The skin diseases often rely on glycolic acid (Glycolic Acid) and benzoyl peroxide (Benzoyl Peroxide) to treat them. However, the order of application of the two is related to the efficacy and skin safety, which cannot be ignored.

Glycolic acid is a fruit acid and the like, which has the effect of rejuvenating the skin. It can exfoliate, make the skin delicate and smooth, and help dredge pores and promote skin metabolism. Benzoyl peroxide is effective in antibacterial and anti-inflammatory, and is beneficial to acne and other diseases.

If glycolic acid is applied first, the stratum corneum of the skin is slightly thinner and the permeability is increased. At this time, following the use of benzoyl peroxide, it may be easier to penetrate into the deep layers of the skin and exert antibacterial properties. However, glycolic acid makes the skin more sensitive, and benzoyl peroxide is also irritating. The superposition of the two makes the skin unbearable, causing redness, swelling and tingling.

On the contrary, the use of benzoyl peroxide first can first inhibit Propionibacterium acne and control inflammation. Then use glycolic acid to use its rejuvenating power to promote skin repair and renewal. However, benzoyl peroxide may affect the activity of glycolic acid and reduce its rejuvenating effect.

To determine the order of application of the two depends on the quality of the skin. Those with strong skin tolerance can first glycolic acid and then benzoyl peroxide to obtain high efficiency benefits, but they need to pay attention to the skin reaction. For those with sensitive skin, benzoyl peroxide should be used first, and then glycolic acid should be used when the skin adapts, and the dosage and frequency should be reduced slowly, so as to keep the skin healthy and make the best use of its medicinal stone.
