What is the Renuva?
Renuva is part of the new wave of aesthetic Erbium lasers.
This new generation of Erbium lasers work similarly to CO2 lasers in that the erbium laser focuses directly on the water found in the skin tissue. This causes the surface cells to vaporize. When combined with thermal injury, rapid production of collagen is induced, resulting in tighter, more refined skin.
The laser has a wavelength of 1550nm and absorbs water in the tissue much more effectively compared to CO2 laser technology.
This allows for less intense thermal injury and ablation to the surrounding tissue which will help achieve better results with a faster recovery time.
The laser reaches as far as the reticular dermis. The Renuva Erbium laser is more of a superficial ablation treatment compared to the traditional CO2 laser. Also, the changes in skin color utilized during CO2 laser ablation that correspond with tissue depth are not present with the Erbium laser due to the fact that it does not cause the same coagulative effect. Instead, pinpoint bleeding it utilized to monitor for proper depth of treatment.
