Struggling with acne even after trying benzoyl peroxide, salicylic acid, or retinoids? Red light therapy (RLT) could help. It’s gentle, safe to use at home, and easy to add to your routine. Let’s keep it simple.

Why Try Red Light Therapy?

  • Reduces redness: Calms inflammation so pimples look less angry.
  • Speeds recovery: Boosts skin cell energy to heal breakouts faster.
  • Balances oil: Some people see less shine with steady use.
  • Extra boost: Many devices pair red with blue light to fight acne bacteria.

When Will You See Results?

Stay consistent. Most people notice changes in 4–8 weeks. By 12 weeks:

  • Fewer pimples
  • Less redness
  • Smoother, clearer tone

Quick How-To

  1. Wash and dry your face.
  2. Skip harsh products before using.
  3. Follow the timing on your device.
  4. Use it 3–5 times a week.
  5. Stick with it for at least 8 weeks.

Who Should Pause First?

Check with your doctor if you:

  • Take photosensitizing meds
  • Have open wounds or severe irritation
  • Are sensitive to light

Picking the Right Device

  • Wavelengths: Red (630–660 nm). Add blue (415 nm) if breakouts are common.
  • Style: Masks cover the whole face. Handhelds spot-treat. Panels work for face and body.
  • Ease of use: Choose the one you’ll actually use often.

  • Expecting overnight results
