What is the best way that is cost efficient to get rid of scars and skin discoloration? (Photos)

I would start treating the scar with Kareskin Body Brightening Kit followed by fractional laser and light chemical peels. Best, Dr. Karamanoukian#Realself100 Surgeon

Thanks for your question and posting pictures.  The dark spot look like you have post-inflammatory hyperpigmentation (PIH).  After a personal consultation, we would probably recommend the PicoSure Laser with the FOCUS and/or Flat Lens for pigment correction.  The FOCUS lens also works well on scar reduction.  PicoSure is safe for all skin types.  Depending on the severity of the pigment, it will probably take 1 to 4 treatments.  Best of luck.
