Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Conditions Skin
Locks In Moisture
Fights Bacteria
Protects skin from environmental damage

Traditional Use
Beaked hazel nut extract has been used in North American traditional medicine and indigenous skincare preparations as a skin-conditioning and nutritive ingredient, similar to its European hazel counterparts.
