Blue light (around 415–450 nm) targets acne‑causing bacteria, helping to reduce breakouts and control oil.
-
Red light (around 630–660 nm) penetrates into the dermis to stimulate fibroblasts, boosting collagen and elastin for firmer, smoother skin.
-
Near‑infrared (NIR, around 800–850 nm) reaches deeper tissues, reducing inflammation, easing redness and supporting healing and circulation.
-
Cells absorb the light energy, which triggers biochemical reactions that improve repair, reduce inflammation and enhance overall skin function over time.
-
There is no heat or damage to the skin surface, making LED suitable for regular use and for sensitive skins when used correctly.
