Time compliance: It is recommended to remove the sheet within 15 to 20 minutes after attaching it.
Prevents reverse osmosis: Prevents the sheet from losing moisture from the skin as it dries.
Optimized absorption: Utilizing the golden time when active ingredients are most efficiently delivered.
Minimize skin irritation: Prevents contact dermatitis that may occur with prolonged application.

Actual practice review
In the past, I used to feel like it was a waste, so I left the sheet mask on until it completely dried. But after removing it, my face felt even tighter. Now, I set a 15-minute alarm and remove the sheet mask while it's still damp, and I can definitely feel the dryness inside my skin. Even though it's a hassle, I've realized that sticking to the right time is much more effective than using expensive masks. Thanks to this, my morning makeup looks much better.
