What is the main benefit of using a toner in skincare?

Using a toner in skincare primarily serves to balance the skin's pH levels. After cleansing, the skin can often be left feeling slightly unbalanced, especially if the cleanser used is alkaline. Toners help to restore the natural acidity of the skin, which is typically between 4.5 and 5.5. This balanced pH is crucial for maintaining the skin's moisture barrier, protecting against bacteria, and optimizing the performance of subsequent skincare products.

While toners can have additional benefits such as removing leftover impurities or makeup residue, the core function focuses on achieving that pH balance. This ensures that the skin remains healthy, hydrated, and can better absorb serums and moisturizers that follow in the skincare routine. Masks that provide sun protection, removal of makeup, or added moisture are accomplished through different specific products, rather than the fundamental purpose of a toner.
