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.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Locks in moisture
Traditional Use
A modern cosmetic ingredient derived from fermented and lysed (broken down) lactobacillus bacteria. Developed in the 21st century as part of the probiotic and microbiome-focused skincare movement.
