The laser Sandro Dual by WON technology, is a dual-wavelength laser Alexandrite (755nm) and Nd: YAG (1064nm), able to work in hybrid mode.

Hybrid mode triggers the two beams in a single impact, providing more effective treatment results.

Sandro also exists in Alexandrite version only.

Sandro DUAL : Main Features

  • High efficiency on various clinical indications thanks to the Hybrid System, first realization in South Korea.
  • Fast transition between 755nm & 1064nm modes consequence of Hybrid mode.
  • Shortened treatment time thanks to the spot diameter of 20 mm.
  • Economic benefits with a reasonable estimate of maintenance costs.
  • “Top Hat” beam profite with high energy densities.
  • Safety : Measurement of epidermal temperature in real time.
  • Customized memory processing protocols.



  • Hair removal for all phototypes
  • Pigment lesions
  • Melasma – alex toning
  • Vascular lesions
  • Skin rejuvenation and skin laxity (pores, wrinkles) – genesis mode
