Does snail mucin actually work?

For hydration and a smoother, calmer-looking complexion, yes: snail secretion filtrate is one of the more reliable K-beauty ingredients. It combines glycoproteins, hyaluronic acid and light exfoliating compounds, so skin tends to look bouncier and more even with consistent use. It is not a wrinkle eraser or a blemish treatment, but as a lightweight hydrating layer it earns its cult following.
