there ARE such things out there. Google Infini by lutronic or Scarlet RF by uh...a korean company i cant recall. basically its heat (via radiofrequency)+needling
They should make handheld devices
They should. The cost for RF needling that my derm offers is outrageous. But it's definitely not easy to make handheld needing devices delivering uniform and effective energy.
Well, i've done electric needling for 2-3 times now i think, and i can report my skin is so much more firmer and acne scars, large pores seem to be getting smaller.
The will be my last needling so far going to get fraxel duel 1550 laser done, hopefully if all goes to plan, in the next few months. My plan was to lift my acne scars a bit and so when my skin hits the laser it would infact come with a better result.
