Witch hazel is a topical astringent derived from the bark and leaves of Hamamelis virginiana, the common North American witch-hazel shrub. High concentrations of tannins in witch hazel make it an excellent astringent which means it has the ability to remove excess oil from skin and shrink down pores. those who are exposed to lots of environmental pollutants may apply witch hazel to the face in order to reduce the amount of contaminants that enter pores and, consequently, the amount and severity of blemishes. Also, because astringents remove excess oil, regular use of witch hazel may further prevent blemishes, especially black heads which result from dried sebum build-up in pores.Witch hazel may also be used to treat blemishes already present on the face or other areas of the body. Apply witch hazel with a cotton ball or cosmetic pad to reduce irritation and appearance of acne or other inflammatory skin conditions. Witch hazel applied to bruises can also help to fade discoloration and speed up the healing process of any underlying damage.
The ability of witch hazel to tighten skin and reduce inflammation makes this an ideal natural remedy for treating discoloration and puffiness under and around eyes and is one of the most popular uses for witch hazel. Just make sure not to get any of this natural astringent on the eyes themselves as it will result in significant pain and lingering discomfort from dryness.
Because of its drying and anti-itch power, witch hazel can also be used to counter the effects of skin-irritating plant compounds like urushiol, the sap oil contained in poison ivy, poison oak, and poison sumac that causes contact dermatitis in about 85% of adults who come in contact with it.
