What is the primary function of toner in a skincare routine?

The primary function of toner in a skincare routine is to balance the skin's pH after cleansing. After cleansing, the skin’s natural pH can often be disrupted, especially if harsh cleansers are used. Toners are specifically formulated to help restore this balance, bringing the skin back to its optimal pH level. This process helps to prepare the skin for subsequent products in the skincare routine, such as serums and moisturizers, enhancing their effectiveness.

In addition to balancing pH, toners can also help to remove any residual impurities or makeup left behind after cleansing, contributing to overall skin clarity. While toners may have additional benefits, such as hydrating or preparing the skin for further treatment, their primary role is rooted in pH balancing.
