Laser and IPL hair removal devices

Laser hair removal uses a concentrated wavelength of light, while IPL sends a broader range of light. Both aim to heat pigment in the hair follicle while limiting injury to surrounding skin. Neither works equally well on every hair colour or skin tone, and the wrong settings can cause burns or pigment change.

Professional systems may include Alexandrite Laser, Diode Laser or Nd:YAG Laser, each selected according to the person and treatment area. Home devices are usually lower-powered and require repeated use. Light-based hair reduction may help people troubled by Ingrown Hairs or Razor Bumps, but an active rash or infection should be assessed first.

Before treatment, check the device's intended skin tones, hair colours, body areas and contraindications. Avoid treating recently tanned skin, moles, tattoos, broken skin or areas with an active flare. Shave if instructed, but do not wax or pluck immediately before treatment because the follicle is the target.

Use protective eyewear when required, test a small area if the instructions advise it, and follow the schedule exactly. A trained clinician can tailor settings and recognise when hair growth needs medical evaluation. New coarse hair with other hormonal changes may warrant assessment for Hirsutism; painful recurring folds or nodules may relate to Hidradenitis Suppurativa.

Stop using the device and contact a clinician for blistering, marked swelling, severe pain, crusting or persistent colour change. Seek care for spreading warmth, pus or fever. Do not continue treating an area that has become increasingly sensitive, numb or inflamed, and arrange review if hair growth or bumps are changing rapidly.

Is my skin tone and hair colour suitable for this device? Which wavelength or light system is safest for the area? How should I protect moles and tattoos? Could my hair growth or bumps reflect a condition needing treatment before hair reduction?
