Stubborn pigmentation from melasma, sun damage, and post-inflammatory hyperpigmentation demands professional intervention when topical treatments fail but safety depends critically on matching laser technology to pigmentation depth, skin tone, and melanin behavior. TL;DR Picosecond lasers (PicoSure, PicoWay) use ultra-short pulses that shatter pigment with minimal heat generation, reducing post-inflammatory hyperpigmentation risk especially for darker skin tones [1] Q-switche
