Is snail mucin safe for acne-prone skin?

Snail mucin is generally well tolerated by blemish-prone skin because it is lightweight, non-stripping and free of heavy oils, so many people use it to add hydration without clogged-looking pores. As with any new product, patch test first and introduce it slowly, since a small number of users find richer snail formulas too occlusive for very congested skin.
