Picosure can lighten dark areas.It is designed for tattoo removal and hyperpigmentation. A combination of bleaching cream composed of hydroquinone, treating in and trial incline could be used for weeks prior to laser for about 4 weeks followed by microdermabrasion followed by photorejevsntion with picosure .A test spot can determine that your skin tolerates the laser
Like Dr Emer says, you have got to be cautious. Yes, the Picosure is my go to laser for PIH, but I would use it in the Focus setting, 8 mm spot, then 6 mm. I like to start my patients on HQ before treatments. SPF +++++ of course. You will require 2-3 sessions. All the bestDr Davin Lim Laser, Surgical and Cosmetic Dermatologist. Brisbane, Australia.
