Brand note

COSRX is the K-beauty brand that built its reputation on snail mucin — specifically the Advanced Snail 96 Mucin Power Essence, a sticky, hydrating essence that creators consistently describe as a staple for dehydrated or compromised skin. The texture is the trade-off: it's gloopy and can feel tacky, but that's also what makes the hydration last. If you're new to snail or want a simple, affordable hydrator that plays well with stronger actives, this is the entry point.
