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.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Conditions Skin
Reduces Inflammation
Softens & Smooths
Traditional Use
Buckwheat has been used in Traditional Chinese Medicine and European folk medicine for circulation and inflammation. Historically applied topically for skin conditions, and modern skincare recognizes its antioxidant and skin-strengthening properties.
