Red light therapy panel: what to know before use

A panel contains light-emitting diodes that direct selected wavelengths toward a treatment area. Red light is different from ultraviolet light, yet different devices vary in wavelength, intensity, coverage and controls. A panel may be used for a skin-care goal, but marketing language should not be treated as a diagnosis or a promise of a particular result.

Light may feel warm, and temporary redness can occur. It does not treat every cause of acne, pigment change, rash or hair concern, and a panel cannot replace examination of a changing or unexplained skin lesion.

Read the manual, clean the skin, remove products that the instructions say to avoid, and keep the panel at the stated distance. Use eye protection when required and never stare into the LEDs. Begin only as directed rather than extending exposure. Review photosensitising medicines and medical conditions with a clinician or pharmacist. Stop for blistering, severe discomfort, eye symptoms or a reaction that persists. Clean shared surfaces and avoid using the device over broken or infected skin unless advised.

Seek medical review for a mole or patch that changes, bleeds or fails to heal, or for a rash that spreads with pain, swelling or drainage. Urgent care is appropriate for facial swelling with breathing difficulty, severe eye pain or vision changes after exposure.

What is this panel designed to treat? Is it suitable with my medicines? What eye protection and exposure schedule apply? How will we judge whether it is helping?
