Which of the following is an effect of using astringents like witch hazel?

Using astringents like witch hazel effectively decreases oiliness on the skin. Astringents are designed to tighten the skin and reduce the appearance of enlarged pores, which can be beneficial for individuals who have oily or acne-prone skin. When applied, witch hazel can control excess sebum production and help absorb oil, leading to a fresher appearance.

This action can help prevent acne breakouts and provide a clear, matte finish, making it a popular choice among those looking for oil control in their skincare regimen. Astringents typically work by drawing moisture away from the skin's surface, which contributes to that oil-reducing effect; however, this does not necessarily mean they are hydrating, soothing, or exfoliating, which are effects associated with other types of products.
