Is laser hair removal safe for darker skin?

Yes, with the right technology, and the technology is the entire answer. Laser hair removal works by targeting pigment, which historically made darker skin risky: older wavelengths could not tell follicle pigment from skin pigment. The 1064 nm wavelength Aerolase uses passes through the skin's surface pigment with minimal absorption and delivers its energy at the follicle, which is why treatment here is safe for deeper and tanned skin tones.
Why wavelength decides safety
A hair removal laser finds its target by color: melanin absorbs the light, converts it to heat, and the heat disables the follicle. The complication is that melanin also lives in the skin itself, and the darker the skin, the more surface melanin competes for the laser's energy. Shorter wavelengths absorb strongly at the surface, which on deeper skin tones risks burns and post-inflammatory hyperpigmentation, the darkened patches that can follow skin injury.
Longer wavelengths change the math. At 1064 nm, absorption by surface melanin drops sharply, so the energy travels past the skin's pigment and concentrates where the follicle sits. Same principle, safer physics.
Fitzpatrick types, named plainly
Clinics grade skin on the Fitzpatrick scale, from type I (always burns, never tans) to type VI (deeply pigmented). The scale exists because device settings that suit one end can harm the other. Aerolase's delivery, an ultra-short, high-powered pulse with no skin contact, paired with its 1064 nm wavelength, is what lets Marie treat across the scale, including tanned summer skin that many clinics turn away.
Assessment still comes first. Safe-for-every-tone describes the technology's range, not a license to skip the individual read of your skin at consultation.
What to ask any clinic
If you are comparing providers, two questions do most of the vetting: which wavelength will be used on your skin, and how the plan changes for your skin type. Vague answers to either are the signal to keep looking. A clinic treating deeper skin tones should be able to name its technology and its reasoning without hesitation.
Common questions
Can I be treated with a tan?
Aerolase's 1064 nm energy is suitable for tanned skin, which is unusual among hair removal platforms. Your current skin state is still reviewed at consultation before treatment.
Does darker skin need more sessions?
Session count is driven by hair growth cycles, not skin tone; the typical series is the same 3 to 6 sessions. What changes with skin type is the settings and safety approach, not the arithmetic.
What about very light or gray hair?
The laser targets pigment in the follicle, so very light, red, or gray hairs respond less regardless of skin tone. An honest consultation will tell you where your hair falls before you commit to a series.
