What should you know about a laser hair removal IPL device?

IPL is intense pulsed light, not a single-wavelength laser. It sends a range of light wavelengths into the skin, where pigment in the hair absorbs some of the energy. Repeated treatments are needed because follicles respond best during particular growth stages. Very light, grey, or red hair may respond poorly because it contains less of the target pigment.

The wrong setting or unsuitable skin can cause excessive heat, irritation, blistering, or pigment change. IPL may reduce shaving-related problems such as [Ingrown Hairs](/symptoms/ingrown-hairs/), but it is not a treatment for every cause of excess hair, including [Hirsutism](/conditions/hirsutism/).

Check the device’s skin-tone guidance, shave as instructed, and perform a patch test. Avoid tanning, sunburn, and self-tanning products around treatment. Keep the flash window flat against clean, dry skin and protect the eyes; never flash over a tattoo, dark mole, open wound, or active infection. Do not increase the setting simply because hair growth is slow.

A clinic may instead recommend a tailored [Diode Laser](/technology/diode-laser/) or another professional option such as an [Nd:YAG Laser](/technology/nd-yag-laser/), depending on your skin and hair.

Pause IPL and contact a clinician for blistering, severe pain, spreading redness, pus, or a persistent dark or pale patch. Seek prompt care for eye pain or vision changes after facial use. A reaction that is worsening rather than settling should be assessed before any further flashes.

Ask whether IPL fits your skin tone and hair colour, whether your medicines increase light sensitivity, how to test the device, which areas are unsuitable, and how to respond if the skin changes colour.
