Er:Glass non ablative fractional laser at 1540nm

Er:Glass operates at 1540nm where the main chromaphore is water, although it is not absorbed as strongly as ErYag at 2940nm, it penetrates the skin more deeply and is non ablative. The main uses of the Er:Glass laser are for skin resurfacing and the treatment of surgical and acne scars, stretch marks and wrinkles. It is also used for the treatment of melasma.

In order to leave a large portion of the epidermis and basal layer undamaged in order to promote healing the beam is fractionated and there is a choice of heads providing either 10 x 10 or 18 x 18 fractionated beam patterns. The square fractionated pattern is the most efficient for ensuring even treatment.
