Because while CO2 laser technology is one of the most effective treatments for aging and skin abnormalities, it cannot completely eliminate deep wrinkles or excessive sagging. Additionally, the results are not permanent—as you continue to age, you will develop more wrinkles. For this reason, repeated treatments may be recommended.
It’s also important to understand that CO2 laser resurfacing is much more intensive than other skin treatments. The laser removes layers of tissue while leaving some targeted areas (called “bridges”) untreated. These bridges then help replenish damaged areas, a healing process which takes anywhere from two to four weeks.
To achieve the maximum benefit from fractionated CO2 laser resurfacing and reduce the amount of time necessary to recover, there are a number of steps that can be taken. Reduce or eliminate exposure to the sun, pretreatment of the skin with an exfoliant /metabolic accelerant such as Retin-A and an agent to reduce melanocyte, pigment-producing cell, activity. Botox and other neurolytic agents are also helpful in reducing muscle activity and prolonging the results from resurfacing.
