Witch hazel is a common ingredient in which type of products?

Witch hazel is well-known for its astringent properties, making it a popular ingredient in products designed to soothe and calm the skin. It is commonly used in toners, aftershaves, and other skincare formulations aimed at controlling oil or treating minor skin irritations, which aligns with the functions of bulking agents and absorbents. These types of products benefit from witch hazel's ability to tighten pores and reduce inflammation.

While witch hazel can also be found in some moisturizers and potentially in sunscreens, its most prominent applications are within the realm of astringent and absorbent products. Hence, it is more accurate to associate witch hazel with bulking agents and absorbents due to its primary functional qualities in the skincare and cosmetic industries.
