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.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Locks In Moisture
Traditional Use
Used for over 4,000 years in Egyptian, Indian Ayurvedic, and traditional African medicine as a healing and conditioning oil for skin and hair; documented in ancient Egyptian cosmetic and medicinal texts.
