What Are Astringent Ingredients?
Ferrous Sulfate has astringent characteristics.
Astringent ingredients in cosmetic products shrink or tighten the skin and reduce oiliness. This results in a temporary reduction in the appearance of pores and an overall smoother, firmer skin texture. Astringents can also help to remove excess dirt and oil from the skin, making it feel clean and refreshed. They are commonly found in toners, cleansers, and other skincare products targeted toward oily or acne-prone skin.
