What's Er: glass laser (1540nm) systems?

The Er:glass laser systems comes with a wavelength of 1540 nm. The laser beam of the Er:glass laser is weakly absorbed by melanin and hemoglobin. Because of the low spread coefficient of this wavelength, the laser beam penetrates very deeply into the skin and is absorbed maximally by the tissue water. This leads to a warming up of the deeper skin layers, the collagen is denatured and cells are warmed up.
Take the active acne for example, the warming up leads to a reduction of the sebaceous glands and therefore a reduction of sebum production. This in turn leads to a "drying out" of the acne.

6.Powerful cooling system(guarantee the long time working) 

Advantage:

2) The stratum corneum remains in place, eliminating wound healing issues and allowing to rapid healing.
3) Fractional columns prevent unnecessary heat accumulation, as opposed to the more painful delivery method of scanning devices.
4) Ease of treatment - It does not require topical anesthesia or dye application, minimizing preparation and clean-up time.
5) Fractional laser treatment is safe for most skin types, which includes fitzpatrick skin types IV and V; Asian, Indian,-Hispanic and lighter toned black skin.
