LED Light Therapy, Explained (Without the Jargon)

Red, blue, amber — what each wavelength actually does, and how to build a weekly routine that works.

LED Light Therapy, Explained (Without the Jargon)

LED light therapy uses specific wavelengths of visible light to trigger different responses in the skin. It's non-invasive, painless and — crucially — has no UV, so it won't damage skin the way sun exposure can.

Red light (around 630nm) is the collagen wavelength: it supports firmness and a plumper look. Blue light (around 415nm) targets the bacteria behind breakouts. Amber (around 590nm) calms redness and soothes sensitivity.

The magic is in consistency. Three to five 20-minute sessions a week beats one long session. Always start on clean, bare skin, and follow with your moisturizer afterward.

Key takeaways

  • Red = firmness, Blue = blemishes, Amber = calming.
  • Consistency beats intensity — short, regular sessions win.
  • Use on bare skin, moisturize afterward.
