Colostrum: the beauty ingredient Rosé from Blackpink and Dua Lipa swear by
From Kourtney Kardashian’s Lemme to Jennifer Aniston-approved Armra, colostrum is everywhere – but is the ‘new collagen’ worth the hype?
Colostrum is the first milk produced by mammals immediately after giving birth and before mature milk comes in, and bovine colostrum – the kind used in supplements and skincare – is extraordinarily dense with bioactives. “It’s a bioactive cocktail that you don’t find in standard cosmetic ingredients,” says Susie Wang, founder and chief creative ambassador at 100% Pure. She points to epidermal growth factor and insulinlike growth factor-1, which stimulate cell regeneration and collagen production; immunoglobulins, antibodies that support the skin’s immune defences; and lactoferrin, an anti-inflammatory and antimicrobial protein that can soothe reactive skin and help neutralise acne-causing bacteria. Colostrum’s “liquid gold” nickname, she notes, refers to both its colour and composition.
