What is the primary purpose of using astringents on the skin?

1. To hydrate and moisturize the skin.

2. To remove excess oil and tighten pores.

3. To exfoliate dead skin cells.

4. To provide sun protection.

The correct answer is: To remove excess oil and tighten pores.

The primary purpose of using astringents on the skin is to remove excess oil and tighten pores. Astringents are typically formulated with ingredients that have a drying effect, which helps to reduce oiliness on the skin's surface. This is especially beneficial for individuals with oily or acne-prone skin, as it can help manage shine and reduce the likelihood of clogged pores that can lead to breakouts. Additionally, astringents have the ability to constrict the tissues, which contributes to the tightening of enlarged pores. This tightening effect can create a smoother appearance to the skin and provide a refreshing sensation. The formulation of astringents usually includes ingredients like witch hazel, alcohol, or salicylic acid, all of which have properties that can help achieve these results. The other options highlight functions that are not typical of astringents: hydrating and moisturizing is the role of emollients, exfoliation refers to removing dead skin cells which is primarily done using scrubs or chemical exfoliants, and sun protection is provided by sunscreens, not astringents. Therefore, focusing on the oil-removal and pore-tightening properties clearly illustrates why the correct answer is associated with the intended function of astringents.
