NIRA is a non-ablative, non-fractional 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 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 transform skin.
