Functions
Anti-Sebum
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Binding
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.
Nourishes & Protects
Traditional Use
Yeast fermentation has been used in traditional food and beverage production for thousands of years. Its application in skincare is a modern development based on the amino acids and B vitamins produced during fermentation.
