This novel concept is meant to define your chin/jawline. Soothing natural ingredients and caffeine combine to add contour and definition to your face. I did not like the feel of the sponge-y glue material mask after unwrapping it but it did not bother me once it was on my face. It was stronger than I imagined and did not wildly stick in my hair, which was my biggest worry.I think it was soothing, I kind of liked the feeling. I was a strong mask that did not interfere with talking, eating, or drinking. My favorite part, it was a surprise, was that the soft scent was pleasant. It lingers the entire time and did not fade away. It was not pungent or offensive, rather natural and not medicine-y. It did not smell like a locker room or menthol related. I am not certain that it will take the place of losing a little more weight but it did make me feel like I had a tighter profile after a few tries.
