In recent years, skincare products have seen an increasing demand for natural and unconventional ingredients, most notably 'snail mucin' or 'snail mucus', which has become a key component in many creams, serums, and masks, especially after its widespread popularity on social media platforms like TikTok. Although the idea of using this sticky substance may seem strange at first, preliminary scientific studies suggest it may offer a range of skin benefits, including enhanced hydration, improved elasticity, help in reducing the appearance of fine lines and wrinkles, and overall skin health support, according to Health.

What is snail mucin?

Snail mucin is the slimy substance that snails or slugs secrete as they move. This substance plays a vital role in the snail's life, helping it adhere to and glide easily over various surfaces, protecting its delicate skin from external factors, maintaining hydration, and reducing the risk of inflammation and infection.

The use of this substance is not limited to nature; interest in it dates back centuries. The ancient Greeks used it to treat dry skin, reduce inflammation, and prevent early signs of aging. It later entered some alternative medicine applications and was used in medical products such as certain types of surgical glue. Today, it has become a common ingredient in skincare products, including creams, serums, and masks, thanks to its moisturizing and skin-renewing properties.

Potential benefits of snail mucin

Studies on the benefits of snail mucin are still limited, and research is ongoing to confirm its effectiveness conclusively. However, preliminary results suggest it may contribute to skin hydration, accelerate wound healing, stimulate cell regeneration, help prevent infection, and even have promising properties in inhibiting the growth of certain types of skin cancer.

Hydration

Snail mucin contains hyaluronic acid, one of the most popular ingredients used in skincare products due to its high water-retaining capacity. This acid helps deeply hydrate the skin by enhancing moisture retention within the skin and reducing water loss, giving the skin a plumper, smoother, and firmer appearance, especially for those with dry skin.

Studies also indicate that using products containing snail mucus may help support the skin's natural barrier, the protective layer that maintains skin moisture and protects it from harmful environmental factors and pollutants that can cause dryness and damage.

Anti-aging properties

Researchers suggest that the anti-aging properties of snail mucus are due to its active ingredients, such as glycolic acid, a type of alpha hydroxy acid widely used in skincare, along with copper peptides known for their role in supporting skin health.

Glycolic acid stimulates collagen production and promotes cell regeneration and the formation of new skin cells, which helps improve skin appearance and reduce signs of aging. Snail mucus also boasts antioxidant properties that help protect skin cells from damage caused by oxidative stress and free radicals, which are among the primary factors associated with skin aging.

A study published in 2020 showed that daily use of products containing snail mucus was effective in improving signs of skin aging in a group of women aged 45 to 65. The results indicated a significant reduction in the appearance of fine lines and wrinkles, along with improved skin elasticity, radiance, smoothness, and hydration, as well as enhanced skin barrier function and increased firmness.

Antimicrobial activity

Since snail mucus protects the snail itself from infection as it moves across various surfaces, researchers have hypothesized that it may also possess antibacterial and antifungal properties in humans.

Several studies have shown that snail mucus secretions can inhibit the growth of certain types of bacteria and eliminate them, and may help reduce skin inflammation, especially when applied to wounds. In some experiments, snail mucus demonstrated effectiveness surpassing some common antibiotics, but these results still require further clinical studies to confirm.

Wound healing assistance

Snail mucus has anti-inflammatory properties, thought to be partly due to its content of allantoin, a natural compound known for its soothing and skin-repairing properties.

The ability of snail mucus to reduce inflammation, prevent infection, and stimulate cell regeneration helps accelerate the wound healing process and supports the skin's natural recovery after injuries.

Studies indicate that snail mucus may help regulate the stages of wound healing in both humans and animals. For this reason, it is sometimes used as a natural adhesive to help protect the skin, cover chronic wounds, and promote healing.

Skin cancer prevention and treatment

Early research suggests that snail mucus may hold promising potential in combating melanoma, the most dangerous type of skin cancer; some studies have shown that mucin components may help eliminate skin cancer cells and limit their spread.

There is also preliminary evidence indicating that snail mucus may help inhibit the growth of certain malignant tumors, believed to be related to its antioxidant properties. However, these findings are still in early research stages, and snail mucus cannot be considered a cancer treatment; more clinical studies are needed to prove its efficacy and safety.

Potential risks and side effects

Available data indicate that most people tolerate skincare products containing snail mucus well, but studies on the long-term safety of their use are still limited.

It is recommended to avoid using these products in individuals with allergies to snails, shellfish, or mollusks, as this allergy may be relatively common and can, in some cases, lead to serious allergic reactions.

Therefore, it is advisable to perform a patch test before first use by applying a small amount of the product to a limited area of skin and waiting 24 hours to ensure no unwanted reaction occurs.

Prominent signs of possible allergy include:

- Itching

- Rash

- Redness or irritation of the skin

- Watery or irritated eyes

- Nasal congestion
