The DUOGlide combines two laser systems into one device. On the one hand, the device contains the classic CO2 laser. The laser plays an important role, especially in surgery for the removal of skin lesions. The heat release immediately causes bleeding to stop. Another area of application is fractional treatment - especially in scar treatments and skin renewal, the small holes that are made in the skin, together with the heat development, lead to collagen formation, tightening and improvement of the skin's appearance. This is exactly where the second wavelength comes in, the wavelength (Er:glass) 1,540 nm, unlike CO2, is not ablative (removing) and leads to deep warming, collagen stimulation and achieves a very high level of effectiveness. At 1,540 nm there is NO skin opening, crusting and downtime. The wavelengths can be used separately - for best results, both wavelengths are often used, depending on the dermatological need.
