What is the primary benefit of using toner in skincare?

The primary benefit of using toner in skincare is to balance the skin's pH after cleansing. Cleansing can disrupt the natural acidity of the skin, which typically has a pH around 4.5 to 5.5. By using toner, individuals can help restore this balance, promoting a healthier skin environment.

This restoration helps the skin to function properly, which can lead to better absorption of subsequent skincare products such as serums and moisturizers. Toners may also help to tighten pores and remove any residual impurities left after the cleansing step, but the key role is balancing the pH.

Other options, while they mention important aspects of skincare, do not accurately represent the primary function of a toner. For instance, moisturizers provide hydration, sun protection involves SPF products, and makeup removal is typically handled by cleansing products rather than toners.
