Soothed, radiant skin. If that’s something you’re constantly searching for, allantoin skin-care products should be on your radar. According to cosmetic chemist Ginger King, who previously lent her expertise to Allure, allantoin is an ultra-calming ingredient known for its ability to deeply hydrate skin, guard the skin against inflammation, and even heal minor wounds. Much like other popular soothers like cica, madecassoside, and aloe, the star ingredient is completely gentle enough to use on sensitive skin. 

To further speak to allantoin’s benefits and versatility, Y. Claire Chang, MD, a board-certified cosmetic dermatologist at Union Square Laser Dermatology in New York City, previously mentioned that she often recommends allantoin-spiked products to patients dealing with irritation and dryness from retinol and glycolic acid. This is because allantoin is a humectant and is able to draw in moisture from its surroundings into the skin, preventing trans-epidermal water loss.

While allantoin has been a mainstay in Korean skin care for years, plenty of brands stateside are following suit and incorporating the sensitive-skin-friendly ingredient into their own formulas.
