The primary function of toner in skincare is to balance the skin's pH and remove impurities. After cleansing, the skin's pH can become unbalanced, often leaning towards the alkaline side due to the ingredients in cleansers. Toners help restore the skin's natural acidity, which is crucial for overall skin health.

Additionally, toners can remove any residual traces of makeup, dirt, and oil that may remain after cleansing. This step enhances the skin's readiness to absorb subsequent products like serums and moisturizers effectively. By ensuring that the skin is clean and balanced, toners prepare the skin for the next steps in the skincare routine, promoting a healthier complexion.
