Is using a sheet mask every day really good for the skin?

We recommend using just one mask a week. For maximum results, try our Healing Kit. It comes with four packs and is great to be used once a week.


Where and how should I keep sheet mask?

Sheet masks are generally good for 2-3 years from the date of manufacture if not opened. Keep it in a cool and dry place, not exposed to the direct sunlight.

If you want to keep it in a fridge, do not keep it straight up but lay it down. Otherwise, essence will flow down and not evenly soak into the sheet. If you keep it upright for too long, the sheet mask may crumple up.
