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.
Microbiome Support
Works with the ecosystem of bacteria living on your skin. A balanced microbiome = fewer breakouts, less irritation, stronger barrier. The new frontier of skincare.
Barrier Repair
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
