What is the primary purpose of using a toner in skin care?

The primary purpose of using a toner in skincare is to remove residual impurities and balance the skin's pH. After cleansing, some traces of dirt, oil, or makeup may still remain on the skin. A toner helps to further cleanse the skin and ensure that it's completely free of impurities. Additionally, many toners are formulated to restore the natural pH balance of the skin, which can be disrupted by cleansing products. Maintaining an appropriate pH level is essential for healthy skin, as it helps to support the skin's barrier function and overall appearance.

While moisturizing the skin effectively, providing sun protection, and enhancing skin color are important facets of an overall skincare routine, they do not capture the primary aim of a toner. Moisturizers cater specifically to hydration, sunscreens focus on UV protection, and cosmetic products can enhance appearance but are different from the fundamental role of toners in achieving a clearer, more balanced complexion.
