What is the primary benefit of using toner in skin care?

Using toner in skin care primarily serves the function of restoring pH balance to the skin. After cleansing, especially with alkaline-based cleansers, the skin’s natural acidity can be disrupted. This can lead to dryness, irritation, and a compromised skin barrier. Toners, particularly those formulated with beneficial ingredients, help to re-establish the skin’s optimal pH level, which typically ranges from about 4.5 to 5.5.

Maintaining this balance is crucial for overall skin health, as the right pH helps to preserve the skin’s natural moisture, protect against harmful bacteria, and facilitate proper function of the skin. Additionally, a well-balanced pH supports the effectiveness of subsequent skincare products, ensuring they can penetrate the skin properly and provide their intended benefits.

Other options, while they may have some relevance in the context of skin care, do not capture the primary role of toner as effectively. Hydration can be achieved through other products, like moisturizers or hydrating serums. Protection against sun damage is primarily provided by sunscreen. While some toners can help in removing residual makeup or impurities, this is not their main function.
