Questions

Is snail mucin cruelty-free?

Reputable brands collect mucin without harming snails, but standards vary by brand — check the brand's own sourcing statement if this matters to you. It is not vegan by definition.

Does snail mucin heal acne scars?

No ingredient "heals scars" in a cream. Snail mucin helps hydrate and can improve the look of skin texture over time, but set expectations accordingly.
