What exactly is snail mucin?

According to Dr. King, snail mucin is an excretion from the snail. It can often be referred to as snail slime and may be labeled as snail secretion filtrate on ingredient lists. “It's made up of properties like glycoproteins, hyaluronic acid and glycolic acid, all of which have long-documented benefits for the skin,” she says.

And while we can thank Korean beauty for bringing this hydrating ingredient stateside, Dr. King says using snail mucin for skin care originated with the Chileans. “In the 1980’s Chileans snailbreeders found their hands to be very soft after handling the snails, leading to the Chilean snail cream, Elicina.”

What are the benefits of snail mucin?

Now that we know what exactly snail mucin is, let’s talk about what it does. While there hasn’t been a significant amount of research or studies done on the effects of snail mucin, there are a few conclusions that can be drawn solely from the makeup of the mucin itself.

Thanks to the hyaluronic acid in the mucin, it has moisturizing properties that support the skin barrier and help lock in moisture. The glycolic acid helps to stimulate collagen production that not only helps diminish fine lines and wrinkles, but it also helps to give your complexion a radiant, youthful glow. Dr. King says it also contains zinc which is anti-inflammatory and allantoin which soothes irritation. So, all in all, you can expect skin to be softer, more moisturized and glowing with consistent use of snail mucin.

Are there any negatives to using snail mucin?

As stated above, there isn’t’ a wide range of research available about snail mucin, but Dr. King suggests it’s a pretty well tolerated ingredient. She does warn that “as with any ingredient, allergies are possible.” So, it’s always best to apply a bit to a small area of skin to test for reactions before applying all over your face.

What do you look for in a snail mucin product?

According to Dr. King, when looking for an effective snail mucin product, you should look for a formula that combines antioxidants or retinol, as well as common skincare staples like vitamin C, glycolic acid and other hydrating ingredients. Most commonly, you’ll find snail mucin in serums or creams and Dr. King says often serums will have a higher concentration of snail mucin and can be used for anti-aging benefits. If you’re looking for more of the mucin’s hydrating properties, opt for a cream. Ahead, a mix of various snail mucin-infused formulas from serums to essences to creams.
