Bought with my own money (Perio Claren White Now)

I brush my teeth well, but my teeth aren't a nice color, so I bought this at Olive Young.

White Now teeth whitening patches for simple and convenient self-teeth whitening care

First, apply the patch without touching the gums and leave it on for about an hour; bubbles will gently form, and whitening will occur.

It seems like my skin has brightened a little, but consistent use is necessary for results.

Please be careful if you have wounds in your mouth or weak gums, and since it takes quite a while, to some extent

Patience is required.
