I have been using one for about 7 or 8 weeks. After 3 I noticed my lashes were fuller and longer and really strong. Now after 7 ish weeks they are like false ones but natural iykwim but I am not sure what to do now. It says 12 weeks but after that do they go back to how they were before or do I stop now as they are long enough .Do I use all the time or is it a one off treatment and my lashes will stay long and thick now. Anyone know? I really recommend them several people have asked if they are false!
