What is the primary function of astringents in skincare?

The primary function of astringents in skincare is to tighten and cleanse pores. Astringents contain ingredients that help reduce the appearance of pores by constricting the skin and removing excess oil and impurities. This tightening effect can be beneficial for individuals with oily or acne-prone skin, as it can help reduce shine and prevent clogged pores, which can lead to breakouts.

Astringents often have antiseptic properties as well, making them effective in cleansing the skin and preparing it for additional treatments by removing surface dirt and bacteria. While they do not provide moisture, exfoliation, or sun protection, their role in enhancing the overall clarity and cleanliness of the skin is significant, particularly in a balanced skincare routine.
