What is the primary function of a toner in skincare?

The primary function of a toner in skincare is to balance skin pH. After cleansing, the skin's natural acidity can be disrupted, especially if a cleanser is alkaline. Toners help to restore the skin's natural pH levels, which supports its barrier function and overall health. This balancing act is crucial for preparing the skin to better absorb subsequent products, such as serums and moisturizers, ensuring they work effectively.

While toners can offer additional benefits, such as hydration or soothing properties, their main role focuses on pH balance. Hydrating toners often contain moisturizing ingredients, but these are supplementary to the primary function. Similarly, while some toners contain exfoliating agents or soothing components, those are not the core purpose of a toner in a skincare routine. Being aware of these distinctions helps in selecting the right products for specific skin needs and enhances the effectiveness of the overall skincare regimen.
