What is a common side effect of using benzoyl peroxide?

Benzoyl peroxide is a well-known acne treatment that works by killing acne-causing bacteria and promoting skin turnover. A common side effect associated with its use is dryness and irritation of the skin. This occurs because benzoyl peroxide has a strong drying effect, which can lead to a decrease in the skin's moisture levels. It can inhibit sebaceous gland activity, leading to reduced oil production, but this reduction in oil can also contribute to dryness and irritation, especially if the product is used excessively or if the skin is particularly sensitive.

It's important for users of benzoyl peroxide to follow instructions carefully and possibly to incorporate moisturizers or other soothing products into their skincare routine to mitigate these effects. Recognizing and managing dryness and irritation can help maintain a healthy balance while treating acne effectively.
