Before you reach for those ‘miracle’ creams or book an invasive procedure, try LED light therapy
If someone had said a few years ago that the answer to our most pressing skin concerns would come from a ray of coloured lights, we would have been sceptical. Light therapy has been around for centuries; the modern technology as we know it was developed by Nasa to help with the healing of astronauts in space, and to help regulate their sleeping patterns. LED light therapy is also used medically to treat jaundice and a type of depression called seasonal affective disorder.
Its aesthetic use includes softening the signs of ageing, treating pre-cancerous skin cells, and combating sun damage and acne. The treatment is becoming increasingly popular, and celebrities like Chrissy Teigen, Beyoncé and Anne Hathaway are all fans.
LED light therapy (also called photo dynamic therapy) is less invasive than laser treatments while still giving effective results. Four different types of visible light are used: red, blue, green and yellow. The lights are used at different wavelengths, combinations and pulses to penetrate and treat different layers of the skin. It stimulates skin cells to jumpstart processes like regeneration and collagen production.
