There is no scientific evidence to suggest that snail mucin directly causes milia. Milia are small, white bumps that can form on the skin when dead skin cells get trapped beneath the surface. They are typically caused by factors such as clogged pores, excess oil production, or skin trauma.

Snail mucin, on the other hand, is a popular ingredient in skincare products known for its hydrating and soothing properties. It is rich in proteins, glycolic acid, hyaluronic acid, and other beneficial compounds that can help improve skin texture, promote collagen production, and enhance overall skin health.

However, it's important to note that everyone's skin is unique, and some individuals may be sensitive or have a specific reaction to certain ingredients. If you have concerns about using products containing snail mucin or if you notice any adverse effects on your skin, it's best to consult with a dermatologist or skincare professional for personalized advice.
