What should you know about hand held laser hair removal?

The device targets pigment in the hair shaft and transfers heat toward the follicle. Hair grows in cycles, so repeated sessions are needed as different hairs enter an active growth phase. Results vary with hair colour, skin tone, body area, device type, and hormonal influences. Handheld products may use different technologies, including alexandrite, diode, or Nd:YAG laser systems.

Temporary redness, warmth, swelling around follicles, or mild sensitivity can occur. A patch test helps reveal how your skin reacts before a larger area is treated. This method is not suitable for every device, body site, or skin condition.

Read the device instructions, shave rather than wax or pluck before treatment when directed, and begin at the recommended setting. Keep the skin clean and dry, protect the eyes as instructed, and avoid treating irritated, sunburned, infected, or recently tanned skin. Do not pass repeatedly over one spot in the same session. Avoid picking at treated follicles and protect the area from strong sun afterward.

Stop treatment and seek medical advice for blistering, marked swelling, severe pain, pus, spreading redness, or a change in skin colour that does not settle. A clinician can also assess recurring ingrown hairs, razor bumps, or unexpected excess hair before you continue.

Ask which device suits your skin and hair, whether a test spot is appropriate, how often to treat the area, and which medicines or skin products require a pause.
