This product felt sticky and constricting on my face. I felt like my face couldn't breath, it was a bit suffocating on the skin. It bothered me so much that I was unable to fall asleep with it on and decided that if I wanted to sleep that night I had better wash it off. I was relieved to have it off my skin! Birchbox gave little instruction regarding this product. I wasn't sure if it was a mask or a lotion, obviously I applied it as a lotion. I will spot treat areas to see if it can be tolerated is tiny portions. If not, it will soon be in my trashcan. Honestly, I can't think of a product that I have disliked this much, ever. I typically use mid to high end products, but I am willing to try most any skincare product. This was a huge disappointment!
