What should you know about SMD laser diode?

Diode lasers emit a specific band of light that is absorbed by pigment in a target. For hair reduction, the target is pigment in the follicle; heat then limits the follicle’s ability to produce hair. Because hair cycles through growth phases, treatment is planned as a course rather than a single visit.

The handpiece may feel warm, prickly, or like brief snaps against the skin. Temporary redness or swelling around follicles can occur. Results vary with hair colour, thickness, skin tone, hormonal influences, the body area, and device settings.

Before a session, avoid tanning and tell the provider about medicines, recent irritation, active infection, tattoos in the area, and a history of unusual scarring or pigment change. Follow instructions about shaving and avoid waxing or plucking if advised, because the follicle is the treatment target.

After treatment, keep the skin cool and protected from sunlight. Use gentle products, avoid picking the follicle bumps, and wait for irritation to settle before applying fragranced products or exposing the area to intense heat.

Ask the clinic for advice if redness lasts longer than expected, pain increases, or blisters, crusting, marked swelling, or light or dark patches develop. Seek urgent help for breathing difficulty or swelling of the lips, tongue, or throat.

Ask whether diode laser is appropriate for your hair and skin contrast, how the settings will be tested, how shaving should be timed, how many visits are likely, and how to protect treated skin from sunlight.
