It is considered more nutrient rich than what is produced during the rest of lactation. The colostrum used in skin care is generally sourced from cows or goats and can have a yellowish coloration (whereas milk is grayish white). In studies, colostrum has been shown to protect against the erosion of the length of telomeres (compounds at the end of chromosomes) in skin and defend against oxidative stress, enhancing skin health and decreasing the visible effects of skin aging. Some research also points to colostrum having the ability to disrupt factors that trigger dark spots and discolorations. Colostrum can be considered an upcycled ingredient since it is often a byproduct of commercial milk production. Usage levels of colostrum in cosmetics haven’t been firmly established; however, its safety isn’t in question for topical use.
