How it works
Snail secretion filtrate is a complex mixture that naturally contains hydrating and skin-conditioning components such as glycoproteins, glycosaminoglycans (including hyaluronic-acid-type molecules), allantoin and small amounts of glycolic acid. It is widely documented as hydrating, soothing and skin-smoothing; composition varies by source and processing.
