What is the main function of a toner in skincare?

The main function of a toner in skincare is to balance the skin's pH and remove impurities. After cleansing, skin may become slightly acidic, and a toner helps to restore that balance, which is important for maintaining healthy skin. Additionally, toners can effectively remove any residual makeup, dirt, or cleanser left on the skin after washing, ensuring a deeper clean. This prepares the skin for subsequent treatments like serums and moisturizers by allowing better absorption of these products.

While some toners may have exfoliating properties, moisturizing effects, or added sun protection, these are not the primary purposes of a toner. The focus remains on achieving pH balance and enhancing the clarity of the skin by eliminating impurities, which are key components for effective skincare routines.
