치아 미백 제품 효과가 있다니 좋네요
It's Aura Whitening Gel.
I have tried various teeth whitening products, such as pen-type and brush-type ones.
The gel dispenses well, and it is the easiest to apply.
It seems to be quite effective, too.
It didn't work the first time, but it seems to get brighter after using it 2 or 3 times. If I use it consistently, it seems to maintain the result.
