Fractionated CO2 is the gold standard resurfacing laser. It delivers microbeams of light but penetrates deeper than the Erbium pixel treatment, for even better results in treating coarse wrinkles, scars, hyperpigmentation and precancers. Preferred treatment is as a series of 3, no closer than 6 weeks apart then can be done yearly. The recovery time is about 7 days, in which period you will have swelling, redness, minor discomfort and some peeling.
