Which product is designed to purify and balance the skin's pH level?

1. Cleansing Milk

2. Toner

3. Moisturizer

4. Exfoliant

The correct answer is: Toner

The product that is specifically designed to purify and balance the skin's pH level is toner. Toners are formulated with astringent ingredients and other beneficial agents that help to remove any residual impurities after cleansing, while also restoring the skin's natural pH balance. After cleansing, the skin can often be left slightly acidic, and using toner helps to bring it back to its ideal pH level, which is typically around 5.5. This balancing is important because it can enhance the skin’s overall health, prepare it for better absorption of subsequent skincare products, and reduce the appearance of pores. While cleansing milk is primarily used for gentle cleansing without stripping the skin of its natural oils, it does not focus on pH balancing. Moisturizers are intended to hydrate and lock in moisture but do not typically address pH levels. Exfoliants work to remove dead skin cells and improve skin texture but are not designed to balance pH. Thus, toners stand out as the go-to product for purifying the skin and maintaining its pH equilibrium.
