What should you know about CNI laser diode?

Diode lasers emit a concentrated wavelength absorbed mainly by pigment in the hair shaft. Heat travels toward the follicle and can reduce its ability to produce a new hair. Results depend on hair colour, thickness, growth phase, skin tone, treatment settings, and the area treated. Several appointments may be needed because follicles respond best when hairs are in an active growth phase. The device is not the same as a razor or wax: it aims to affect the follicle rather than simply remove hair at the surface.

Tell the clinician about recent tanning, medicines that increase light sensitivity, a tendency to develop raised scars, and any active rash or infection. Follow the clinic's instructions about shaving and skin products. During treatment, you may notice warmth, snapping sensations, or temporary redness around follicles. Afterward, protect the area from strong sunlight, avoid picking or vigorous rubbing, and use only products recommended for the treated skin. Contact the clinic if irritation is worsening rather than settling.

Seek prompt medical advice for spreading blistering, severe swelling, intense pain, pus, fever, or skin colour changes that continue to worsen. Eye exposure, vision changes, or treatment near the eye with inadequate protection needs urgent assessment. A clinician should also review a persistent burn-like area or a rash that does not improve.

Ask which wavelength and settings suit your skin and hair, how many visits may be reasonable, what cooling or eye protection will be used, and which medicines or skincare products should be paused.
