Many lasers carry real risk for darker skin. Pico Laser's mechanism is a genuine exception — here's the actual reason why, and what to expect.
Many laser and light-based treatments carry a real risk for darker skin tones (Fitzpatrick IV through VI): post-inflammatory hyperpigmentation, or PIH — new dark marks that appear after treatment, sometimes more stubborn than the original concern. This isn't a minor footnote. It's the reason many patients with darker skin have been told certain lasers simply aren't an option for them.
Pico Laser (PicoLazer) is a genuine exception to that pattern, and the reason is mechanical, not marketing. Its picosecond pulses shatter pigment through a photoacoustic effect rather than through heat — and heat is the primary driver of PIH risk. Less heat generated means meaningfully lower risk, regardless of skin tone.
Melanin-producing cells in darker skin are more reactive to heat and inflammation. Devices that rely on significant thermal energy can overstimulate those cells as a side effect of treating the intended target, producing new dark marks. Pico Laser's lower-heat mechanism sidesteps much of that risk by design, not through a special "dark skin setting" tacked on afterward.
Patients with darker skin have often been told "no" more than they've been told "yes" when it comes to laser treatment, sometimes without much explanation. I want patients to understand the actual reason Pico Laser is different — it's not that darker skin is being treated as an exception, it's that this device's mechanism was never especially risky for darker skin to begin with.
Is Pico Laser safe for darker skin tones?
Yes, Pico Laser is generally considered one of the safer laser options for darker skin tones (Fitzpatrick IV-VI) because its picosecond, photoacoustic mechanism generates significantly less heat than traditional lasers, lowering the risk of post-inflammatory hyperpigmentation.
Why do some lasers cause dark spots in darker skin?
Heat-based lasers can overstimulate melanin-producing cells in darker skin, triggering post-inflammatory hyperpigmentation — new dark marks that can be more stubborn to treat than the original concern. Lower-heat devices like Pico Laser carry meaningfully less of this risk.
Does Pico Laser work as well on darker skin as lighter skin?
Yes, with appropriate settings. Pico Laser's mechanism is not dependent on strong contrast between pigment and surrounding skin the way some devices are, making it effective across a wide range of skin tones when properly calibrated by an experienced provider.
Do I still need a patch test if I have darker skin?
A thorough consultation and skin assessment is standard before any laser treatment, particularly for darker skin tones, to confirm appropriate settings and candidacy before proceeding with a full treatment.
Dr. Mortazavi will confirm candidacy and calibrate treatment specifically for your skin.
