The primary purpose of a toner in skincare is to balance the skin's pH after cleansing. When you cleanse your skin, especially with products like soap or foaming cleansers, the natural acidity of the skin can be disrupted. Toners help restore the skin's natural pH level, which is essential for maintaining healthy skin. This balancing act is particularly important because a properly balanced pH can aid in ensuring the skin barrier functions effectively and prevents issues such as dryness, irritation, and breakouts.

In addition to pH balancing, many toners also contain ingredients that can provide hydration, so while hydration is a benefit, it is not the primary purpose. Toners do not primarily serve as sun protection; that function is typically fulfilled by sunscreen products. While some toners may have exfoliating properties, this is not their main role, as exfoliation is usually achieved through other skincare treatments or products specifically designed for that purpose.
