What is the effect of using a toner in a skin care routine?

Using a toner in a skincare routine is primarily beneficial for balancing the skin's pH levels and removing any leftover impurities after cleansing. After washing the face, the skin's natural balance can be disrupted, which is where toner comes into play. It helps restore that balance, ensuring that the skin is prepared to absorb subsequent products more effectively.

Moreover, toners can help eliminate traces of makeup, dirt, and oil that may remain on the skin after cleansing, contributing to a clearer and more refreshed complexion. This action is particularly helpful for those with oily or acne-prone skin, as it can prevent clogged pores and breakouts.

In contrast, while some toners may have a hydrating effect, their primary function does not focus on moisturizing. Sun protection falls under the domain of dedicated sunscreens, and primers are specifically designed to prepare the skin for makeup application, which is not the role of a toner. Thus, option B accurately reflects the key functions of toner in a skincare regimen.
