A It would be highly unusual or unlikely that your filler dissolved from kissing. Filler is dissolved using a product called Hylenex which would have to be injected directly into the lips where the filler is to dissolve it. Your body can metabolize some of the HA in the filler over time, but not from kissing someone 6 weeks after filler. Are you feeling like you have lost some of the "umph" in your lips? Kysse is a very soft natural product, I would not utilize this to give someone more "plump" as its just not a "plump" product. Honestly, Refyne isnt my go to for someone who is looking for a plump lip either. If you were looking for a plumper appearance I would recommend Restylane - L, Defyne, Juvederm Ultra or Ultra Plus, Vollure, or Versa+.
