Alpha-hydroxy acids are common in skincare products and are the main ingredient in many chemical peels. When AHAs first became available, they caused substantial irritation because they were too acidic.
Today, AHAs are more buffered and usually have a pH of 3.5 or higher, making them friendlier for skin’s crucial balance. However, it’s important to keep in mind that overusing acids can potentially dissolve the lipid layers and break down the skin.
Lactic acid cleansers are gentle, so they can be used regularly, but when it comes to other AHAs, like glycolic acid, you shouldn’t use them every day.
