Why skin tone matters
Lasers target pigment in hair. In medium to darker skin, the skin also contains more pigment, which raises the risk of burns or pigment changes if settings are wrong.
Suitable technology
Longer-wavelength lasers such as the Nd:YAG are generally considered safer for darker skin types. A patch test is sensible before a full session.
How many sessions
Several sessions spaced weeks apart are usually needed, with occasional maintenance. Results are a reduction in hair, not a guarantee of permanent removal.
Before and after
Avoid sun exposure and tanning, and do not wax or thread between sessions. Report blistering or darkening of the skin promptly.
The takeaway
Ask who operates the laser, which device is used, and how settings are chosen for your skin type.
