The other issue with snail mucin is that many of the results you see are anecdotal, and there hasn’t been much clinical research done on the ingredient. There’s also the questionable ethics of its retrieval. Dr. Sanjay Batra, Co-Founder of WETHRIVV and former Adjunct Professor at the Wake Forest Institute for Regenerative Medicine, explains: “Snail mucin is a defensive mucus that comes when the snail is under threat — think poking it with a stick — or worse, exposing it to high G-force in a centrifuge, or even exposing the snail to heat or chemicals to force them to release the mucin.” However, dermatologist Andrea Suarez, MD, FAAD, also known as Dr. Dray, who is vegan, explained in a YouTube video review of the now-viral CosRX Advanced Snail 96 Mucin Power Essence, that the snails aren’t harmed in the process of extraction, and if the snails are being harmed it can cause changes in the mucus’ composition and eventual efficacy. Not to mention, testing cosmetics on animals in Korea is banned. Basically: Happy snails, happy life.
