Witch Hazel Extract

Botanical Astringent

Also known as: Hamamelis Virginiana Extract

Description

Witch hazel extract is derived from the bark and leaves of Hamamelis virginiana, a North American shrub with a long history of use as a topical astringent and anti-inflammatory agent. It is rich in tannins (8–12%), particularly hamamelitannin (a unique galloylated sugar), along with proanthocyanidins, catechins, gallic acid, and flavonoids (quercetin, kaempferol). These polyphenolic constituents confer potent astringent, anti-inflammatory, antioxidant, and mild antimicrobial properties. Importantly, alcohol-free distillates retain some volatile anti-inflammatory compounds but lose most tannins; thus, extract form determines clinical efficacy. Witch hazel tightens pores, reduces sebum, and soothes irritated skin without the harshness of synthetic astringents. [Thring 2011]

Mechanism of Action

Hamamelitannin and related tannins precipitate surface proteins in the stratum corneum, creating a tightening (astringent) effect that constricts superficial blood vessels and reduces transepidermal water loss through protein cross-linking. Anti-inflammatory activity is mediated through inhibition of 5-lipoxygenase, suppression of TNF-α release, and scavenging of reactive oxygen species (superoxide and hydroxyl radicals). Proanthocyanidins protect endothelial integrity and reduce capillary permeability. Gallic acid and catechins provide bacteriostatic activity against Cutibacterium acnes and Staphylococcus aureus. The astringent action also reduces apparent pore size and controls excess sebum on the skin surface. [Thring 2011]
