My American friend who is in Korea for aesthetic training recommended this. It's not bad. The feeling on the lips is sticky and I personally don't like it. I wish it comes with a spatula too so that I don't have to dip on my finger in and risk contaminating the whole lip mask.
The sticky feeling of the lip mask is still there when I woke up, and there are patches of dead skin on my lips. So, the result is actually good. 😊
