Snail Secretion Filtrate description

Snail secretion filtrate, also known as snail mucin, is the filtered form of the secretion from several varieties of snails. This secretion comes from the snails’ singular foot and is used both to help snails move as well as adhere to surfaces. At first used in Korean beauty (or K-beauty) products, it is now gaining popularity in skin care formulations worldwide. This ingredient is found in Protelixan PF manufactured by Cobiosa and distributed by MMP International in the US and Canada. Research finds that far from being a fad, there is benefit in topical application of snail secretion filtrate. The secretion contains numerous skin-friendly ingredients, including elastin, collagen, allantoin, glycolic acid, antioxidants, and even peptides. A growing number of studies are showing that snail secretion filtrate helps mitigate multiple signs of aging, especially visible damage caused by years of unprotected exposure to the sun. Usage levels of snail secretion filtrate hover between 2–5%. One note: the snail secretion filtrate extraction process is considered non-harmful to the snails, since the secretions (which are essentially a byproduct) are humanely collected from live specimens. However, this is considered an animal-derived ingredient so would not qualify as vegan.
