I plan to remove a "small flower mandibular glove" chin implant with .6cm projection. Is removal or replacement better? (photo)

The glove-chin implant very minimally improved my profile profile, while I no longer like my smile (chin looks too big). I want to take out the implant, but I'm very worried that the skin will look droopy, so I wonder if you would suggest I replace the .6 by a .3. Does that even exist (can you help me find this)? Or will the "pocket" create the illusion a small implant? Will the skin go back to normal..? I also planned ultherapy before the removal - Should I postpone? I'm in my mid 30s.
