Astringents are substances that cause temporary tightening or drying of skin or mucous membranes. In the world of skincare, astringents are often used to add balance to oily skin, reduce the appearance of pores, and help to prevent breakouts. However, there are other terms used to describe astringents. For instance, some may refer to astringents as toners, which can also remove impurities from the skin and give a healthy glow. Others may use the term "pore minimizers," which connotes their function in reducing the size of skin pores. Apart from that, names like skin refreshers, clarifiers, and purifiers are also synonyms for astringents. Whatever the term used, the function of astringents remains the same, which is to help achieve a radiant and healthy-looking skin.
