Why LED Light Therapy Actually Works

By Estée Laurent

It looks like magic, but the science behind clinical-grade light therapy is quietly remarkable. Here is what the wavelengths are really doing.

LED therapy is one of those treatments that sounds almost too gentle to matter. No downtime, no discomfort — just a warm glow of coloured light and a quiet twenty minutes.

Red for renewal

Red wavelengths penetrate deeply, stimulating fibroblasts and encouraging the production of collagen and elastin. Over a course of sessions the skin feels firmer and behaves younger.

Blue for balance

Blue light targets the bacteria implicated in breakouts, calming inflammation without the harshness of topical treatments.

Best of all, LED pairs beautifully with almost any other in-studio treatment.
