Can glycolic acid be used after benzoyl peroxide

If you want to know whether glycolic acid can be used after benzoyl peroxide, you need to investigate the properties of the two in detail. Benzoyl peroxide is often used as a medicine for acne. It has strong oxidizing properties, can break the wall of Propionibacterium acne, and can cause keratolysis. Glycolic acid is one of the fruit acids with small molecules and good permeability. It can exfoliate, promote epidermal cell renewal, and increase skin hydration.

However, when using both, be careful. Benzoyl peroxide has strong oxidation, and glycolic acid has a certain acidity. The two are used successively, or there may be a chemical reaction, causing skin discomfort. If benzoyl peroxide is used first, it will make the skin slightly dry and desquamated, and the skin barrier will be slightly weaker at this time. If glycolic acid is used immediately, it should be used because of its exfoliation properties, or increase skin irritation, such as redness, tingling, itching, especially for those with sensitive skin.

If you want to use it, try it on a small scale first. After cleansing, apply a thin layer of benzoyl peroxide to the local area, and there will be no adverse reactions after a few days, and then use a small amount of glycolic acid there. If it is still the same, you can gradually expand the scope of use. And strict sun protection is required after use, because it makes the skin more sensitive to light.

In short, it is feasible to use glycolic acid after benzoyl peroxide, but you must be cautious, according to your own skin condition, step by step, to ensure skin health.
