What is a key benefit of using toner in skincare?

1. Provides sunscreen protection

2. Balances skin's pH level

3. Hydrates the skin

4. Exfoliates dead skin cells

The correct answer is: Balances skin's pH level

Using toner in skincare is often recognized for its ability to balance the skin's pH level. After cleansing, the skin can become slightly alkaline, which is not ideal for maintaining its overall health and function. Toners typically help restore the skin's natural acidity, which often ranges between a pH of 4.5 and 5.5. This balanced pH level is crucial as it supports the skin's barrier function, protecting against environmental aggressors, and helps to optimize the absorption of subsequent skincare products. While toners can have various additional benefits, such as providing hydration or containing exfoliating ingredients, their primary role often centers around pH balance. This ensures that the skin remains in a state ready to receive and benefit from moisturizers and serums applied afterward. Other options may refer to benefits more commonly associated with different products in a skincare routine, such as moisturizers for hydration or exfoliants for removing dead skin cells.
