Mr George Christopoulos explores the science behind LED photobiomodulation
For millennia, light has been recognised for its regenerative effects, and recommended for healing and skin revitalisation.1 In the past 20 years, the use of light therapy, in the form of light-emitting diode (LED) phototherapy or photobiomodulation, has expanded significantly in medical aesthetics and dermatology due to its non-invasive nature and clinically proven efficacy across various skin conditions.2-13
Biological effects of LED therapy
LED phototherapy is a non-invasive treatment that harnesses specific wavelengths of light energy to elicit targeted biological responses at the cellular level.3,4,14 Unlike laser or intense pulsed light (IPL) treatments, which rely on thermal effects and specific chromophore targeting, LED therapy stimulates existing natural processes at the cellular level without generating thermal damage.15,16 This mechanism of action makes LED phototherapy a safe…
