jellymasks are made mainly with refined alginate. They contain much more alginate than regular rubber masks. That's why jellymask texture is like jelly, which provides extra full hydration and instant cool and soothing effects all at once. Also they create completely a silky soft, vacuum-like seal over the skin. This function is the most important! Under the vacuum seal, the mask pushes hydration and nourishing ingredients (from the mask and also other previously applied skincare ingredients still remaining on the skin) deep into the skin. This is why we suggest using jellymask for 15-20 minutes near the end of a skincare protocol in order to push all applied nutrition into the skin perfectly. Do not forget to follow with sunblock to protect your newly radiant skin!
