Euthymol Whitening

I usually use Euthymol toothpaste from LG Household & Health Care, but I heard they have a product specifically for teeth whitening, so I tried it out.

You just apply the whitening gel, put on the patch, wait a while, and then peel it off. There aren't any super dramatic results, but since I've been using it consistently, I think my skin has gotten about two shades whiter!! Since I can't quit coffee, I guess I'll have to work hard on whitening my skin haha.
