What is the primary purpose of a toner in skincare?

1. To moisturize the skin

2. To exfoliate dead skin cells

3. To balance the skin's pH after cleansing

4. To provide sun protection

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

The primary purpose of a toner in skincare is to balance the skin's pH after cleansing. When you wash your face, the cleanser can disrupt the natural pH balance of the skin, which typically hovers around a slightly acidic level. Using a toner helps to restore this balance, ensuring that the skin can function optimally. This can enhance the effectiveness of other skincare products that follow, such as serums and moisturizers, as these products are better absorbed when the skin’s pH is balanced. Toners can also help to remove any leftover makeup or impurities that cleansing may have missed, further preparing the skin for subsequent treatments. This step is particularly beneficial for those with oily or combination skin types, as it can help to reduce excess oil and minimize the appearance of pores. While moisturization, exfoliation, and sun protection are essential parts of a skincare routine, they represent different functions than that of a toner. A toner is not primarily designed for hydration or exfoliation but rather plays a crucial role in maintaining the skin's natural acidity, which is vital for skin health.
