World first: High Power Planar LED Diode Laser System with 12 flat high-power super-emitting LED's (light emitting diodes)! The ARTMED Planar LED system penetrates deep enough to destroy deeper hair roots. The wavelength of the ARTMED Opera VII is in the near infrared range (NIR) and is 780-840nm! This area penetrates the epidermis and dermis and pushes up to the subcutaneous tissue with the fatty tissue. Thanks to this spectrum, the hair is destroyed more reliably than with laser systmes with only 808nm!
