I've been using it for a while now and I see no changes in my lips, they are not softer nor smoother. The product smells really really amazing (I got the Berry one) and it doesn't stain my pillow case. It's just a nice addition to my night routine and it will last me for a long time. Definatley won't purchase again. (maybe when winter comes and my lips start to get dry the sleeping mask would nourish them...I guess. But this is my opinion so far:)
