If you’ve been exploring SkinTok or K-BeautyTok, you’ve likely come across the buzz surrounding snail mucin. Snail mucin, also known as snail slime, has been gaining popularity for its multitude of skin-care benefits, including hydration and collagen production boost. Surprisingly, snail mucin is not a recent discovery in the world of skincare.
According to board-certified dermatologist Ava Shamban, MD, it emerged as a commercial skin-care trend as early as the 1980s. Snail farmers, who had constant contact with the secretion, had notably well-hydrated, supple, and youthful hands compared to their peers. The history of snail mucin can be traced back to ancient Greece, where it was used for its anti-inflammatory properties and its ability to combat signs of aging.
In this article, two board-certified dermatologists provide comprehensive insights into snail mucin: what it is, how it works, its benefits for the skin, and how to incorporate it into your skincare regimen.
**What Is Snail Mucin, and Where Does It Come From?**
Snail mucin is a natural and highly potent secretion produced by mollusks, composed of proteins, peptides, and proteoglycans, according to Dr. Shamban. It is the clear, shiny, mucus-like trail left behind by snails, serving to protect them. This substance acts as a natural exfoliant and brightening agent, triggers keratinocytes to protect the skin from UV damage, maintains skin hydration, and enhances antimicrobial function.
While various types of snail mucin exist, the most commonly used variety in skincare comes from the species Cryptomphalus aspersa. This particular type has regenerative properties that aid in wound healing, cell proliferation, and fibroblast activity for increased elasticity and anti-aging effects.
**Snail Mucin Benefits for Skin**
Topical application of snail mucin offers numerous skin benefits. According to board-certified dermatologist Jodi LoGerfo, DNP, APRN, FNP-C, it is effective in reducing the appearance of wrinkles, burns, stretch marks, and improving overall skin moisture due to its ability to stimulate collagen production and its antioxidant content. Snail mucin is also praised for its skin-hydrating properties, strengthening the skin’s moisture barrier and potentially serving as an anti-aging treatment that minimizes fine lines and wrinkles.
Additionally, snail mucin possesses antibacterial, anti-tumor, and wound-healing properties. Dr. LoGerfo references a 2018 study published in Biomedicine & Pharmacotherapy, suggesting its anti-tumor potential against melanoma. The wound-healing attributes are likely due to its antibacterial and anti-inflammatory qualities, though further research is needed for conclusive evidence.
**How to Use Snail Mucin**
When searching for snail mucin in beauty products, look for “snail secretion filtrate” or “SSF” as the listed ingredient. It can be present in varying concentrations in products, making it suitable for various applications, such as cleansers, essences, serums, ampoules, fluid lotions, creams, or masks. A popular product that contains snail mucin is the CosRX Advanced Snail 96 Mucin Power Essence. Snail mucin is gentle and compatible with active ingredients like retinoids, salicylic acid, niacinamide, hyaluronic acid, AHAs, and BHAs.
Both dermatologists agree that snail mucin is suitable for all skin types and is generally well-tolerated. However, if you have specific skin concerns, are on medication like Accutane, or are pregnant or nursing, it’s advisable to consult with your healthcare provider before incorporating snail mucin into your skincare routine. Dr. Shamban emphasizes the importance of patch testing or consulting with a board-certified dermatologist when introducing new ingredients or products to your skincare regimen.
