What should you know about pulsed laser diode?

Diode systems are commonly used for laser hair removal. The light is absorbed by pigment in the hair, and heat travels toward the follicle to reduce its ability to produce hair. Hair growth cycles mean that follicles respond at different times, so treatment is usually planned as a course rather than a single visit. The result varies with hair colour, thickness, skin tone, body area, hormones, and device settings. Fine or very light hair may respond differently.

Tell the provider about tanning, medicines that increase light sensitivity, active skin disease, scarring, and recent hair-removal methods. Follow instructions about shaving and avoid plucking hairs if advised, because the follicle needs to remain available to the laser. After treatment, protect the area from sunlight, avoid irritating products, and follow cooling or cleansing guidance. Do not judge the final response while the skin is still red or swollen.

Contact the provider for blistering, severe pain, spreading redness, pus, or a colour change that is worsening. Urgent assessment is needed for facial swelling with breathing difficulty or a serious eye symptom if the face was treated. A patch of altered texture or persistent pigment should be examined before another session.

Is diode laser suitable for my hair and skin colour? Which device settings and cooling method will be used? How should I shave or pause other hair-removal methods? What temporary reactions are expected, and what will prompt a review?
