Hyaluronic acid, retinol, squalene — there’s no end of go-to ingredients that, when added to skin care products, can have major benefits. Beyond the go-tos, a trendy ingredient pops up every once in a while that everyone can’t stop buzzing about. That’s where snail mucin comes in. Yup, you read that right. Search TikTok and you’ll find that videos featuring beauty products containing snail mucin have over 1.1 billion views, with many influencers saying it plumps skin and addresses fine lines. 

But does snail slime help your skin? We turned to board-certified dermatologists with that very question. Below, they explain what snail mucin is and go over the purported benefits — plus, we rounded up top-rated products containing this ingredient.

What is snail mucin? 

Does snail mucin come from the shelled gastropods? It does. “Snail mucin, also known as snail gel, is primarily harvested from the common garden snail (the cryptomphalus aspersa species) without harming the snails,” says Dr. Yoram Harth, a board-certified dermatologist and medical director of MDacne. “The collection process involves agitating live snails to produce the mucin, which is then collected in skin care products.” 

This slime is made up of a few skin-friendly components. “It has gained popularity in skin care due to its composition of proteoglycans, glycosaminoglycans, and hyaluronic acid — all of which are beneficial for the skin,” says Harth. Proteoglycans and hyaluronic acid are hydrating, while glycosaminoglycans support the skin’s protein structures. You should know, however, that though many tout that snail mucin is hydrating and can address fine lines, the science is inconclusive, says Harth. “Laboratory studies have shown it can benefit cell cultures, possibly enhancing collagen and elastin production,” he says. “A placebo-controlled study funded by a product manufacturer indicated that snail mucin could reduce wrinkles over three months with no adverse effects. However, broader and more impartial clinical studies are needed to confirm these effects in humans.”  

How we picked the best snail mucin skin care products

When shopping for skin care products that contain snail mucin, our experts recommend keeping the following in mind: 

  • Ingredients: Snail mucin is the main active ingredient in all products below. Experts also suggest looking for products that pair it with ingredients that have similar benefits to maximize its hydrating and plumping abilities — such as hyaluronic acid and vitamin E.  
  • Formula: Snail mucin can be slightly sticky in texture, which may bother some people. With this in mind, we selected various types of products. For example, if a sticky texture isn’t ideal, a snail mucin cleanser that gets washed away may be a good option. A serum that is worn at night could also be a good idea. Below, we’ve included all types of formulas and products. 
  • Ratings: All selected products have an average rating of 4.0 or above from at least 1,000 reviews.
