  • Simplified switch with on/off button
  • Infrared sensor to measure the distance for treating
  • Integrated timer with 6 LEDs alert indicators (timer up to 2h)
  • Automatic switch off after 2 hours

Through the use of white LEDs technology, patient comfort is significantly optimized

  • Treatment of actinic keratosis completely painless and silent
  • Protection of patient against glare
  • UV and IR free treatment which also warns of risk of sun exposure
  • Much greater freedom to patient (possibility to go to toilets during the consultation without impacting the protocol)

DERMARIS was designed to a large surface with the same intensity. So, it offers a homogeneous treatment of actinic keratosis

Thanks to white LEDs technology, DERMARIS proposes a larger spectrum which covers all peaks of absorption of PpIX (between 400 and 750 nm)
