Colostrum is the first milk produced after birth, and in skincare it’s a refined, protein-dense extract designed to nourish the skin’s surface. Rich in proteins and amino acids, it helps condition skin, support a resilient-looking barrier, and deliver cushiony hydration for a plump, dewy look. A thoughtful pick for dry, delicate, or mature complexions—and for anyone leaning into a soothing, barrier-focused ritual.
