Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Moisturising
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Traditional Use
Milk has been used in skincare since ancient times, notably by Cleopatra and Roman women who bathed in milk for skin softening and brightening. Modern milk protein extracts are derived from this traditional practice, preserving milk's moisturizing and protein-rich properties for contemporary cosmetics.
