Be­fore you reach for those ‘mir­a­cle’ creams or book an in­va­sive pro­ce­dure, try LED light ther­apy

Marie Claire (South Africa) - - BEAUTY -

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.
