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
Lysates are modern byproducts of fermentation created by breaking down bacterial cell walls in the late 20th century. Designed to deliver probiotic metabolites and beneficial compounds without live organisms, supporting skin barrier and immune function.
