I've had PIH under my right eye for almost 2 years now. It's responding poorly to topical bleaching so I'm considering laser to get rid of it, but my derm only has the Q-switched laser. Are there really any advantages of the Q-switched laser over a picosecond laser for treatment of dermal hyperpigmentation? Or is the Q-switched just outdated in this field? From what I find the ps-laser just seems superior. Don't want to risk my results/face with old technology.
