How laser hair removal works — and where it went wrong
Laser hair removal works by targeting the pigment (melanin) in the hair follicle. The laser’s energy is absorbed by that pigment, heating and disabling the follicle so it stops producing hair. The problem for darker skin is that melanin also lives in the surrounding skin — so a laser that cannot tell hair pigment from skin pigment can burn or leave dark and light marks.
That is the source of the old warning. Early single-wavelength devices, especially those tuned for fair skin, genuinely were risky on deeper skin tones. Many people were turned away or, worse, treated anyway and left with damage.
What changed: wavelength
The fix is wavelength. Longer wavelengths penetrate deeper and are absorbed less by surface melanin, so they can reach the follicle while sparing darker skin. The Nd:YAG laser, at 1064 nm, is the gold standard for treating deeper skin tones safely.
The GentleMax Pro we use in Draper is a dual-wavelength platform: an Alexandrite laser (755 nm) that is highly effective on lighter skin, and an Nd:YAG (1064 nm) for darker tones. Having both in one device means the provider can match the laser to your specific skin rather than forcing every patient onto the same setting. It also has integrated cooling that protects the skin surface and makes treatment more comfortable.
Questions to ask before you book anywhere
If you have darker skin, two questions separate a safe clinic from a risky one. First: what laser do you use, and does it have an Nd:YAG wavelength? If the answer is vague or the device only offers one wavelength tuned for fair skin, keep looking. Second: who performs the treatment? Trained providers who adjust settings to your skin type are what keep you safe.
A reputable clinic will also do a test spot if there is any question, and will set honest expectations. Anyone promising to treat any skin on any machine with no caveats is not being straight with you.
Getting the best result
Results build over a series — most patients reach 80 to 90% permanent reduction across six to eight sessions spaced four to six weeks apart, because hair has to be treated during its active growth phase. Prep is the same regardless of skin tone: shave the area the day before or the day of, but never wax or pluck, since the laser needs the follicle intact. Avoid sun and self-tanner before treatment and use SPF between sessions — sun exposure raises the risk for everyone and especially for deeper skin.
Done on the right device by a trained provider, laser hair removal is safe and effective for essentially all skin types today. The technology is no longer the limitation — the clinic is.
