Our verdict
Don't let the name put you off — COSRX Snail Mucin is a cheap, gentle, lightweight hydrator that genuinely earns its cult following. A great everyday layer, and especially handy when summer heat has your skin sweaty but still thirsty.
The short version
It sounds odd and works beautifully. COSRX's snail secretion filtrate essence sinks in fast, layers under everything, and leaves skin hydrated, smoother and a little plumper over time. There's no heavy fragrance and a bottle lasts ages, which is why it's become a permanent fixture in so many routines — and a great lightweight hydrator for hot, sweaty summer skin.
