What is the function of astringents?

Astringents function primarily to help remove excess oil from the skin. They work by contracting the skin tissues and reducing the size of the pores, which can minimize oil production and the appearance of shine, particularly in individuals with oily skin types. These agents can also be effective in controlling acne by clearing clogged pores and reducing inflammation associated with excess oil.

While moisturizing the skin, increasing hair growth, and promoting skin pigmentation are important aspects of skin and hair care, they do not align with the main purpose of astringents, which is focused on oil control and skin tightening. The use of astringents can help maintain a clearer complexion by managing oil levels, which ultimately supports healthier skin overall.
