This ampoule is packed with hydrating (glycerin, hyaluronic acid), soothing (niacinamide, centella, hemp, allantoin, panthenol, St. John's Wort), antioxidant (resveratrol), and barrier-supporting (ceramides, bifida ferment lysate) ingredients. The thick, milky formula comes in a dropper bottle that's tinted brown to protect the product from light exposure. It has no scent.
I've just started using tretinoin, and applying this ampoule before tret really helps reduce irritation and dryness. I think it's going to be a fabulous ampoule for me with cold weather coming where I live.
