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.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Fights acne
Causing bacteria
Locks in moisture
Traditional Use
Developed in the 20th century as a modern antimicrobial agent; silver has been used historically for its antibacterial properties (silver vessels were used to store water and wine), but this specific borosilicate form is a contemporary cosmetic innovation without traditional use.
