Red Light Therapy for the Face: Benefits, Myths & How to Start

Updated · 6 min read · By the Renewa Skin team

Red light therapy has moved from dermatology clinics into bathrooms around the world. With that popularity has come a lot of hype. This guide explains what red light therapy is commonly used for on the face, which claims to be skeptical of, and how to start using it at home.

What is red light therapy?

Red light therapy exposes the skin to low levels of visible red light (roughly 620–700 nm) and sometimes near-infrared light. It does not use UV, so it doesn't tan or burn. It is also called low-level light therapy (LLLT) or photobiomodulation.

What people use it for on the face

Red light therapy is most commonly used as part of an anti-aging skincare routine. People use it to:

  • Support smoother-looking skin and soften the look of fine lines
  • Support a firmer, more radiant-looking complexion
  • Complement their serums and skincare as a relaxing daily ritual
  • Target specific areas such as smile lines, marionette lines, and around the mouth

Myths to be skeptical of

Marketing sometimes gets ahead of the evidence. Be cautious of claims like these:

  • "Results in days" — visible changes typically take weeks of consistent use
  • "Better than fillers or a facelift" — it's a gentle skincare routine, not a procedure
  • "More is better" — longer or more intense sessions than recommended aren't more effective and may irritate skin
  • "Works for everyone the same way" — results vary from person to person

Masks, panels, or handheld devices?

Full-face masks and panels cover a large area at once. Handheld devices are smaller and let you target specific zones — useful if your main concern is the lower face. Some handheld devices, like the Renewa iLift, also add sonic vibration and warmth for a massage-like experience.

For a detailed comparison, see our guide on how to choose an at-home facial device.

How to start

  • Start with clean skin (add a thin serum layer if your device is designed for it)
  • Follow the recommended session length — often around 5 minutes for handheld devices
  • Use it daily and give it at least 4–8 weeks before judging results
  • Take a photo in the same lighting on day one to compare later
  • Keep the light away from your eyes and wear sunscreen during the day

Frequently asked questions

Does red light therapy really work on the face?

Red light therapy has been used in dermatology for years as a gentle, non-invasive treatment. At home, it works best as a consistent, long-term skincare habit; results are gradual and vary by person.

Can I use red light therapy with retinol?

Many people use both. If your skin is sensitive, use them on different nights or use the device before applying retinol, and follow your device instructions.
