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
Lactobacillus bacteria have been used in fermented foods and traditional medicine for millennia. In modern skincare (developed in the 21st century), fermented lactobacillus extracts are used for their probiotic and skin-conditioning benefits.
