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.
Skin Protecting
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Nourishing
Protecting
Traditional Use
A synthetic derivative combining allantoin (traditional comfrey compound for healing) with polygalacturonic acid (plant-derived polysaccharide). Developed for enhanced skin film-forming and conditioning in modern cosmetics.
