I tried this Look Beauty Pretty Animalz calming panda sheet mask when I saw it at Target for only a few dollars. I've never tried a sheet mask before, and I see all of the animal masks online that are super popular right now. The panda face looked really weird, so I don't know why the animals masks are such a craze. It was easy to apply, and you had to let it stay for 20 minutes before slowly removing it and rubbing in the rest of the product into your skin. After the first minute, it did start to sting a little bit, but nothing major. After the 20 minutes I removed the mask and rubbed in the excess product. It felt so soothing afterwards I was in heaven! I can't wait to buy more and use these whenever I'm stressed!
