Face Red Light Therapy: What to Know

Red light therapy exposes the skin to a selected wavelength from light-emitting diodes. It does not remove the surface of the skin like a peel, and it is different from laser treatment. A clinician may discuss it alongside care for [Acne](/conditions/acne/) or [Pimples](/symptoms/pimples/), but it is not a diagnosis or a replacement for treatment of an underlying condition. Home and clinic devices differ in output, coverage, eye protection, and instructions. An [LED Phototherapy Panel](/technology/led-phototherapy-panel/) is one type of device, while [LED Light Therapy](/treatments/laser-and-energy/led-light-therapy/) describes the treatment category.

Read the device instructions and keep the panel at the stated distance and for the stated session length. Clean the skin as directed, remove products that may make it light-sensitive, and use the recommended eye protection. Do not stare into bright LEDs. Tell the clinician about medicines that increase light sensitivity, eye conditions, photosensitive disorders, recent procedures, or a history of unusual reactions to light. Stop if you develop persistent heat, pain, marked redness, a rash, or eye discomfort. Keep a simple record of sessions and skin changes so the plan can be adjusted.

Seek advice if irritation lasts beyond the expected period, acne becomes painful or rapidly inflamed, or a new patch or lesion changes after treatment. Prompt assessment is appropriate for blistering, facial swelling, severe eye pain, vision changes, or symptoms of an allergic reaction. If a breakout keeps returning, have the cause assessed rather than relying on light alone.

What concern are we targeting, and is red light appropriate for it? Which device and eye protection should I use? Could my medicines or skin condition increase sensitivity? How will we judge whether to continue?
