What to know about laser hair removal in skin of colour

Laser energy is absorbed by melanin in the hair and can also be absorbed by surrounding skin. More melanin means the treatment requires a thoughtful balance between targeting the follicle and protecting the skin surface. Darker or recently tanned skin may have a greater chance of temporary lightening, darkening, blistering or burns if settings are unsuitable. Hair colour, thickness, body site and the cause of excess hair also affect the plan. Results are usually hair reduction rather than removal of every hair.

Choose a qualified medical provider who regularly treats your skin tone and can explain the device being used. Ask for a test area when appropriate, disclose tanning, active rashes, medicines and a history of pigment changes, and follow instructions about shaving and sun exposure. Do not wax or pluck the target hairs shortly before treatment if the provider needs the follicle present. After a session, use the recommended cooling and sun protection, and avoid picking irritated skin.

Contact the treating clinic if redness, swelling, pain or heat is worsening rather than settling, or if blisters, crusting, marked colour change or oozing appears. Seek urgent care for severe pain, rapidly spreading swelling or signs of a serious allergic reaction. A clinician should review persistent dark or light patches before another session is scheduled.

Ask which laser or light technology fits your skin and hair, whether a test spot is recommended, what side effects may affect pigmentation, how sessions will be spaced, and what aftercare is needed.
