How often should chemical exfoliants be used on acne-prone skin?

Using chemical exfoliants on acne-prone skin 2 to 3 times a week is optimal for several reasons. Chemical exfoliants, such as alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs), work effectively to remove dead skin cells, unclog pores, and promote cell turnover, which can help mitigate acne.

This frequency allows the skin to benefit from the exfoliation process without overwhelming it, as using them too often can lead to irritation, increased sensitivity, or a compromised skin barrier. A regimen of 2 to 3 times a week strikes a balance that enables effective treatment while minimizing the risk of adverse effects, making it a suitable choice for individuals with acne-prone skin.

In contrast, using chemical exfoliants once a week may not be sufficient to maintain the desired improvement in skin texture and acne reduction, while daily use could lead to irritation and over-exfoliation. Monthly usage would likely not provide the ongoing benefits needed to manage acne effectively.
