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

1. To brighten the complexion

2. To balance the skin's pH

3. To remove dead skin cells

4. To provide hydration

The correct answer is: To balance the skin's pH

Using a toner after cleansing primarily serves the purpose of balancing the skin's pH. Whenever a cleanser is applied to the skin, especially if it contains strong ingredients or is of an alkaline nature, it can disturb the natural acidity of the skin. The skin typically has a slightly acidic pH, which is important for maintaining its barrier function and overall health. By applying toner post-cleansing, you help to restore this natural pH balance more quickly. This is crucial because a balanced pH helps to prepare the skin to better absorb subsequent products, such as serums and moisturizers, enhancing their effectiveness. While toners can also provide additional benefits such as hydration or exfoliation depending on their formulation, the primary and most fundamental role they play after cleansing is to ensure that the skin's pH is re-established.
