For acne treatment, what is typically the purpose of a toner?

The primary purpose of a toner in acne treatment is to balance the skin’s pH. After cleansing, the skin's natural acidity can be disrupted, which may lead to various issues including dryness or increased oil production. By re-establishing a balanced pH level, toners help restore the skin's natural barrier, which can prevent irritation and promote overall skin health. This is particularly important for acne-prone skin, as maintaining balanced pH can help reduce the likelihood of breakouts.

While toners may also provide other benefits such as hydration, exfoliation, or oil control, balancing the skin's pH is a foundational aspect of their role in skincare, especially for those dealing with acne.
