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.
