You may have started a Korean skin care routine that uses products such as Snail Secretion Filtrate. You may be curious about what it does for your skin and how it’s collected.

Snail mucin is collected from the common garden snail Helix aspersa, and is considered a pest. Its secretions are especially rich in proteins and include hyaluronic acid and antioxidants. There are a few methods to collect snail mucin but in all methods the snails are collected and rinsed. Then they are stimulated to produce mucin that is collected.

According to my research, the methods of snail mucin harvesting do not hurt or kill snails.

Snail Secretion Filtrate

Copper Peptides

Copper peptides have anti-inflammatory properties, speeds up wound healing and increases levels of antioxidants.

Glycolic Acid

Glycolic acid is an AHA – a-hydroxy acid, and improves skin texture and can reduce wrinkles, acne scarring, dark spots, hyperpigmentation.

Glycolic acid can be an especially strong irritant depending on pH levels. This means when you layer it on other products, there is a chance you can have a reaction if the pH levels are off. Because of this, I strongly suggest you test snail mucin on a patch of skin to check for allergies. Also try using it alone after a pH balancing cleanser.

Glycoprotein Enzymes

Glycoprotein enzymes are found in mucin, and have water-holding capabilities. This helps with moisturization.

Hyaluronic Acid

Hyaluronic Acid is wound-repairing, moderates inflammatory responses, facilitates cell migration and has skin-healing properties.


  • Stimulates Collagen and Elastin
  • Heals wounded and damaged skin
  • Moisturizes


As stated above, glycolic acid is an strong irritant. You can have bad skin reactions depending on the pH level of your skin. When you layer this on top of other products, your skin’s pH balance is off and the chances of irritation increase.

Test snail mucin products on your skin to check for allergies. If you have a reaction after combining with other products, you can wait about 15-20 minutes after your usual skin care routine to allow the products you put on to be absorbed. After the 15-20 minutes, you can safely apply snail mucin if your allergy is caused by product layering and pH levels.

If you continue to have reactions, you are allergic to snail mucin and should discontinue use immediately.
