What is the primary benefit of using a toner after cleansing?

The primary benefit of using a toner after cleansing is to restore pH balance and remove impurities. After cleansing, the skin's natural pH can be disrupted, particularly if a strong or harsh cleanser is used. Toners are formulated to help bring the skin back to its optimal pH level, which is generally around 4.5 to 5.5 for healthy skin.

In addition to balancing pH, toners often contain ingredients that can help remove any residual impurities left on the skin after cleansing, such as leftover cleanser, dirt, or makeup that might not have been fully washed away. This leaves the skin feeling refreshed and prepared for further skincare products, such as serums and moisturizers, to be more effective.

Hydration is an essential aspect of some toners; however, it is not the primary function, which is more focused on balancing and purifying the skin. While some toners may provide a sun barrier due to added sun protection ingredients, this is not a standard feature of all toners.
