Snail Mucin: Slimy Skincare Miracle or Just a Sticky Trend?

Snail mucin, the slimy secretion that helps garden snails slide, has slithered its way into skincare routines worldwide. Beauty influencers and K-beauty lovers can't stop raving about this slimy ingredient's ability to hydrate, plump, and repair skin. But does snail slime really live up to the hype, or is it just a marketing gimmick? Let's take a closer look at the science behind this skincare craze!

‍

Current State of Knowledge:

Snail mucin, or mucus, is the slime that is secreted by snails for the sake of adhesion or lubrication to surfaces. The mucin is made of a family of glycosylated proteins, allantoin, glycolic acid, hyaluronic acid, copper peptides, and antimicrobial peptides (Starkman and Seed). These bioactive compounds are thought to contribute to snail mucin's purported skin benefits and its use in skincare. Specifically, glycolic acid, which is a type of alpha hydroxy acid (AHA), can act as an exfoliant which can rejuvenate the skin. Additionally, the allantoin “has been shown to increase cell growth, stimulate regeneration of tissues, and rebuild granulation tissue” (Aflatooni et al.), which is why it has such a pull on current skincare formulations. 

Several small clinical studies have investigated snail mucin's effects on skin:

• In a double-blinded  study posted in 2021, it was shown that Snail Soothing and Repairing cream significantly improved skin hydration by day 14 compared with placebo (Theerawattanawit et al.). 
• Studies have shown that secretions from garden snails (Cryptomphalus aspersa) have antioxidant superoxide dismutase glutathione S-transferase activities. Additionally, they have been shown to contain glycosaminoglycans, which can help the skin retain moisture. When skin retains moisture, it can have a more elastic and firm look,  which is why this ingredient is prevalent in skincare (Brieva et al.) (Pitt et al.). 
• A 2019 study in which participants used eye creams that contained glycosaminoglycans showed a  73% decrease in puffiness and 93% reduction in dark circles (Colvan et al.).

Although these findings appear promising, it can be said that most studies that employed snail mucin were of a small scope, of short duration, or from an industrial setup. Further studies from an independent setup over an extensive period of time should be conducted to adequately perceive its effects. 

‍

Methodological Insights:

The body of evidence for snail mucin has the following shortcomings:

• Most studies tested snail mucin as part of a formulation, not as an isolated ingredient. It's unclear if benefits were due to snail mucin alone or synergistic effects with other activities.

• Snail mucin concentration varied widely between studies, making comparisons difficult. Standardized, quality-controlled extracts are needed for consistent research and consumer use.

• Few studies have directly compared snail mucin to well-established skincare ingredients like retinoids, vitamin C, or niacinamide. Head-to-head trials could help determine snail mucin's relative efficacy.

Three Viewpoints on Snail Mucin:

Mainstream Medical: 

Mainstream medical opinion recognizes snail mucin as generally safe and potentially beneficial for skin hydration and barrier support, as shown by Mayo Clinic (Candace Nelson). Limited clinical studies suggest it may improve the appearance of fine lines and skin texture, but experts emphasize that evidence is preliminary and based on small trials or laboratory research. Claims related to anti-aging or cancer protection are considered experimental, and snail mucin is not viewed as a substitute for well-established, evidence-based dermatologic treatments.

Likewise, a board-certified dermatologist at MDCS Dermatology, Dr. Marisa Garshik, states “Snail mucin is thought to help moisturize the skin and help boost hydration. It has been commonly incorporated into K-beauty [Korean beauty] products, now being increasingly recognized for its ability to help nourish the skin” (National Eczema Association). Another dermatologist, Dr. Paul Yamauchi, states “Snail mucin has been noted for its ability to hydrate skin and promote wound healing. In addition, it may have anti-aging properties as it is made up of compounds including peptides and antioxidants that promote collagen synthesis and elasticity. Snail mucin is also known for its anti-inflammatory and soothing properties, which may help to calm irritated or compromised skin” (National Eczema Association).

The American Academy of Dermatology (AAD) does not currently have an official position on snail mucin. However, The National Eczema Association seems relatively in favor of snail mucin, but advises caution and checking in with a healthcare professional.

Holistic / Integrative Perspective

While there is limited information on the holistic or integrative medicine perspective regarding snail mucin specifically, these approaches generally favor natural, gentle, and traditional ingredients in skincare. Holistic practitioners often recommend tallow, botanical oils, and other minimally processed substances that have been used for centuries to support skin health.

‍

Influencer / Public Perspective

Snail mucin has developed somewhat of a cult following within the beauty community, and this is largely attributed to the promotion that has been carried out by beauty influencers on various social platforms. In most cases, the cosmetic formed from the snail mucin has a thick consistency that is slippery enough for viewers to take interest and interact with the content. Many beauty influencers and even physicians who have massive followings online tend to promote the mucin and even commercial brands related to the beauty ingredient through their content. However, this is not always the case because the content does not always separate promotion from facts and is even more influenced by financial relationships and sponsorships.

‍

Synthesis of Viewpoints

Snail mucin has fascinated dermatologists and holistic practitioners and beauty enthusiasts alike with its interesting biochemical properties and skin benefits. Although it is yet to become a cornerstone within the bounds of modern dermatology, it seems snail mucin is slowly becoming a gentle and versatile tool for hydration, anti-aging, and repairing sensitive skin. Snail mucin is, however, no magic bullet solution. A holistic approach integrating protection from UV radiation, proper skincare, and evidence-based external and internal therapies seems imperative for a healthy complexion. Whether or not snail mucin can integrate into such a practice is a question; though it seems highly unlikely it could ever replace it. Social media representatives and supporters should refrain from making farfetched assertions about snail mucin being a “miracle” cure. Although snail mucin is a very interesting and promising find, further studies are required on how snail mucin could ideally be applied and used, and how one should then actually expect tangible results.

‍

Future Directions: 

Several areas exist for future snail mucin research:

1. Component analysis: Break down each compound in snail mucin and test each compound to establish the levels that have bioactivity. This could lead to the development of better products.

2. Delivery technologies: Explore nanoencapsulation, liposomal formulations, or penetration enhancers to improve snail mucin absorption and stability.

3. Applications of regenerative medicine: Conduct tissue culture studies and animals to further investigate its role in wound healing, cell proliferation, and its application in cases of burn, chronic ulcer, etc.
4. Microbiome impacts: Analyze the impacts of snail mucin on skin microbial populations. Snail mucin may possess antimicrobial peptides useful in skin microbial balance, mainly in acne.

4. Microbiome effects: Examine how snail mucin influences skin's microbial community. The antimicrobial peptides in snail mucin may help rebalance skin flora and reduce acne.

5. Cosmetic procedures: Assess pre- and post-treatment use of snail mucin with lasers, microneedling, peels, and other cosmetic treatments. Snail mucin's reparative properties may enhance results and reduce downtime.

Review:

Snail mucin can appear like a hero ingredient that's more gimmick than substance, but it's not the case. It does contain a unique combination of hydration, protection, and repairing agents that make it a promising ingredient with multiple usages, including smoothing, soothing, and anti-aging purposes. While it sounds promising, it's not a miracle solution by any means. It requires more scientific study on how it works, on who it works best on, and how it should be used for the best results. As always, it's essential that your primary concern should always be to protect your skin from the sun, maintain a proper skincare routine, and focus on reliable skincare ingredients. If you are curious about integrating snail mucin into your skincare routine, ensure that you consult the proper healthcare professional to see if it would be a good fit for you. Overall, we hope you learned something new!
