What is the main difference between a cleanser and a toner?

The main difference between a cleanser and a toner lies in their specific functions within a skincare routine. A cleanser is designed to remove impurities from the skin's surface, such as dirt, oil, makeup, and pollution. Its primary goal is to provide a clean base for further skincare products. On the other hand, a toner is used after cleansing to help balance the skin's pH levels, which can be disrupted during the cleansing process, particularly if the cleanser is too harsh. Furthermore, toners can also provide additional benefits like hydration, tightening pores, and preparing the skin for moisturizer.

This distinction highlights the complementary roles these two products play in maintaining skin health. The other options do not accurately reflect the main functions of these products or make broad generalizations that do not apply universally to all skincare formulations.
