Mucin, a glycoprotein component of mucus, plays a significant role in wound healing, including the treatment of scratches and abrasions. Scientific research has demonstrated that mucins, particularly those derived from snail slime (Helix aspersa), promote epithelialization, modulate inflammation, and provide a moist wound environment—factors critical for efficient healing. Several in vitro and animal studies have shown that mucins can accelerate the migration and proliferation of fibroblasts and keratinocytes, essential cells in skin repair. Additionally, mucin forms a protective barrier that helps prevent infection and desiccation of the wound surface.

There is also emerging clinical evidence supporting the use of topical formulations containing mucin or snail secretion filtrate for superficial skin injuries. For instance, randomized controlled trials and dermatological studies have reported improved healing rates and reduced scar formation in minor wounds treated with mucin-based products compared to standard care. This effect is attributed to the bioactive compounds in mucin, including glycosaminoglycans, enzymes, and antimicrobial peptides, which collectively enhance tissue regeneration.

While more large-scale clinical studies are needed to further validate efficacy, the current body of scientific literature provides moderate support (evidence level 3/5) for the use of mucin in supporting the healing of scratches and abrasions, justifying its inclusion in various wound care products.
