What should you know about near-infrared lights?

Near-infrared light sits beyond the visible red part of the light spectrum, so you may not see the beam. In dermatology and aesthetics, it can be delivered by an LED panel or another light device. The intended effect depends on wavelength, intensity, exposure time, distance from the skin and the condition being addressed. It is different from ultraviolet light, which can damage skin.

A session may feel gently warm, although sensations vary by device. Near-infrared light is not a substitute for diagnosis or treatment of every rash, wound or acne problem. Acne and isolated pimples can have different causes, and a clinician may recommend a broader plan if inflammation, infection or scarring is present.

Before treatment, mention medicines that increase light sensitivity, eye conditions, seizure disorders triggered by light, pregnancy, active rashes and recent procedures. Ask which eye protection is required and whether the device is intended for home or professional use. Follow the manufacturer's distance and exposure instructions rather than extending sessions because the light feels mild.

Cleanse gently and avoid placing irritating products on freshly treated skin unless advised. Protect your skin from sunlight as part of routine care, and keep a record of any redness, warmth or irritation. Stop the device and contact the provider if symptoms persist or worsen.

Seek medical advice for painful or worsening redness, blistering, swelling, a new rash, eye discomfort or visual changes after exposure. Urgent help is needed for facial swelling, widespread hives or breathing difficulty. If pimples become deep, tender or leave marks, arrange a skin assessment instead of relying on light alone.

What wavelength and device are being used, and what skin target is intended? How should the light be positioned, how will my eyes be protected, and which medicines or products matter? Ask how improvement will be judged and what treatment will be used if the underlying problem needs medication or another procedure.
