Snail serum has been on the marked for the last few years. This includes release of some products including Tensage. The slime has more recently been found in cosmetic products in Asia and Europe. The snail slime secretes proteins like collagen, glycolic acid and hyaluronic acid which can help rejuvenate the face. In some spas, snails are actually placed on clients faces to directly apply these helpful proteins. It would take some compelling data for most patients to allow snails to crawl on their faces.
