LED lights stimulate our cells and kick-start a number of processes which help rejuvenate the skin. This therapy stimulates cells called fibroblasts which produce collagen. It also slows down the production of enzymes which break down collagen and make older skin lose its elasticity.
LED lights also speed cell production, making skin regenerate faster which creates fresher-looking complexions.
The science sounds convincing, and so it should. Nasa scientists started using LED (light-emitting diode) lights to help grow plants in space in the Nineties. They noticed that when red LED lights shone on astronauts, wounds tended to heal faster. Nasa scientists started using LED lights to help grow plants in space in the Nineties.

Research revealed cells exposed to LED light regenerate 150 to 200 per cent faster than those not stimulated by the light. LED light, or photodynamic therapy, was then developed by Nasa and in 2003 they published a groundbreaking report highlighting its healing properties. It is now used in skin treatments.
LEDs emit light waves of different lengths. The longest (650-730 nanometers) are red and used for anti-ageing treatments due to their cell regenerating properties. Like Jessica Alba, I will be road-testing 'red light' therapy in the hope of turning back the years.
