Cosjet ATR

The WONTech Cosjet ATR series device is PASTELLE’s ‘little brother’, a long pulsed Nd:Yag-type Q-Switched laser in dual wavelength setup (532nm and 1064nm), which is widely used in dermatological and cosmetic/aesthetic medicine, for such treatments like:

  • Tattoo removal
  • Termal pigmented lesions
  • Photorejuvenation
  • Slackening skin

This type of laser has been upgraded several times, with a constant focus on improving both its functionalities and optional features. With its wide range of pulse duration, the COSJET ATR-S Series reflects such redesigned new look.
