Functions
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Masking
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Reduces Inflammation
Traditional Use
Used since ancient Greek and Roman times as a preservative and skin tonic in herbal preparations. Medieval herbalists valued rosemary for circulation and skin health, and it was a key ingredient in the 14th-century 'Queen of Hungary's Water' skincare formula.
