NIRA is a non-ablative, non-fractional 2mW diode laser at a wavelength of 1450nm. It works in a similar way to radiofrequency, by heating the tissues and inducing an inflammatory response. This is very different to epigenetic based photobiomodulation, on which the LYMA Laser is based.
LYMA Laser PRO is a 1450mW near infrared laser at 808nm. The science behind the LYMA Laser is fully backed by peer-reviewed evidence and the energy intensity of the LYMA Laser has been optimised to enable the light to be absorbed in the dermis which is where skin remodelling takes place.
