The primary function of a toner in skincare is to balance the skin's pH. After cleansing, the skin can often become slightly acidic or alkaline, especially if a harsh cleanser is used. Toners help restore the skin's natural pH balance, which is essential for maintaining skin health and function. This aids in preparing the skin for subsequent products, such as serums and moisturizers, ensuring they are absorbed more effectively.

Toners often contain astringent properties that can minimize the appearance of pores and help with oil control, contributing to a smoother skin texture. They can also provide a base layer of hydration and can contain soothing ingredients that calm inflammation, but the key purpose is primarily pH balancing. Therefore, understanding the role of toners is crucial for a comprehensive skincare routine.
