The CO2RE is a fractional CO2 laser by Syneron--Candela that delivers complete facial rejuvenation in a single treatment. It is the perfect treatment to improve skin texture, reduce acne scars and tighten the skin. The level of treatment is determined by the individual's need and their ability to tolerate the "down time". The more aggressive and effective the treatment, the higher the energy (light, mid, or deep). And, correspondingly, the more intensive the post-procedure healing will be. For those of us with more natural ability to tan (people of Asian, Hispanic, Middle Eastern or African heritage), a period of using a medication called hydroquinone may be necessary to make sure that the laser does not change our pigment in an undesirable manner.
