Astringents benefit the skin. Astringents help to cleanse, soften and relieve the skin. Many natural astringents contain water, witch hazel and aloe vera among many other plant and herb extracts. The formulas are intended to soothe and nourish the skin while treating many skin irritations, bruises and cuts. Astringents can play many roles for the skin but always end with the same result, cool, refreshed, and healthy skin.
