Snail mucin is a Korean skincare staple used mainly to hydrate and give skin a plump, dewy, smoother-looking finish. Many people also like it for soothing the look of post-blemish marks. Its benefits are cosmetic and hydration-focused rather than medical treatment.
What is hyaluronic acid and how do you use it?
Hyaluronic acid is a humectant that draws water into the skin for a plumper, hydrated look. In Korean routines it's best applied to damp skin and sealed with a moisturizer on top, so the moisture it attracts stays locked in rather than evaporating.
