I love using these especially on the between brows WTF lines. I wear them overnight and whenever I am hanging out at home. I see a big difference right away but the longer I use them, the better my lines disappeared. Using these for a few weeks straight and I notice quite a difference. They are also kind of training me to not scrunch up my face even when I'm not wearing them, which also helps to permanently make my lines improved. It takes a little time and persistence but they do actually work!
