What should you know about lumigen red light therapy?

A panel or handheld device delivers red light to clean, exposed skin. The session does not remove the surface of the skin, and results depend on the device, the condition being treated, and consistent use. Red light is different from ultraviolet light; do not assume every lamp marketed for the face has the same output or safety features.

Some people consider this approach for inflammatory blemishes or general skin appearance. It is not a substitute for assessing persistent, painful, scarring, or rapidly changing skin problems. For background, see [LED Light Therapy](/treatments/laser-and-energy/led-light-therapy/) and [LED Phototherapy Panel](/technology/led-phototherapy-panel/).

Ask a clinician to check whether light treatment fits your goal, especially if you take medicines that increase light sensitivity or have an eye condition. Follow the device instructions for distance, timing, eye protection, and cleaning. Use it on clean skin unless the treating professional gives different instructions, and stop if you develop marked heat, swelling, blistering, or worsening irritation.

Keep expectations realistic: light therapy may be one part of an acne plan, alongside proven cleansing and prescribed treatments when appropriate. Explore [Acne](/conditions/acne/) and [Pimples](/symptoms/pimples/) for related skin concerns.

Seek medical advice for severe pain, blistering, a spreading rash, eye pain or vision changes after treatment, or irritation that does not settle when use stops. Arrange a skin assessment for a new or changing mark, a persistent sore, or acne that is scarring or affecting your wellbeing.

Ask which device and light setting suit your concern, whether your medicines make you more light-sensitive, how to protect your eyes, and how progress will be assessed before continuing.
