What should you know about NIR LED light therapy?

Near-infrared light is delivered to the skin by LEDs, often from a panel. It is different from ultraviolet tanning light and from laser treatment. Depending on the device and goal, a clinician may use it as part of an acne plan, for redness, or to support recovery after selected procedures. It does not remove a deep cyst, treat an infection, or replace diagnosis of a changing lesion. Results and tolerability vary with wavelength, distance, exposure time, and the condition being treated.

Ask which wavelength, dose, eye protection, and schedule apply to your device. Follow the manufacturer or clinic instructions rather than extending sessions. Clean the skin as directed and remove products that may increase light sensitivity when advised. Protect your eyes whenever the device instructions require it. Tell the clinician about medicines, eye conditions, photosensitivity, pregnancy, and recent procedures. Stop and report significant heat, blistering, swelling, or persistent irritation.

Get medical advice if acne is painful, scarring, rapidly worsening, or accompanied by fever, or if a spot changes in colour, shape, or behaviour. Seek prompt help for facial swelling, breathing difficulty, widespread hives, eye pain, or a burn after treatment. A dermatologist can decide whether LED therapy fits the diagnosis and whether another treatment is needed.

What is the treatment target, and how will progress be judged? Which device settings and eye protection are appropriate for me? Could any of my medicines make light exposure unsuitable? What should I do if my skin becomes hot or irritated?
