Concise answer
Laser hair reduction can be performed on darker skin when the device, wavelength, settings and cooling are selected carefully. Recent tanning and aggressive settings can increase burn and pigment risk.
Hair colour and thickness determine the target, while skin pigment affects how energy should be delivered.
A patch test may be considered, but it does not replace trained assessment and conservative treatment.
When evaluation may help
Consultation is important after previous burns or pigmentation and when the treatment area is tanned, irritated or being treated with photosensitising medicines.
