Perfuming

Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Traditional Use
Found in black pepper, cloves, and other spices, this compound has been used in Traditional Chinese Medicine and Ayurveda for centuries for its warming and anti-inflammatory properties. Recently isolated for use in modern skincare formulations.
