The real answer is that we don’t know. Treatments such as Total FX (combination of Active and Deep FX) and the Fraxel Repair have only been studied for the last couple of years. Both of these systems use a fractionated CO2 laser which has been studied for almost 20 years now.
We do know that dermal thickening (collagen formation) continues through and even after the first twelve months post CO2 ablation. The results tend to last at least 3-5 years with full CO2 and usually longer. I think it is reasonable to expect the same from the current treatments such as Active FX, Deep FX and the Fraxel Repair which actually penetrate much deeper than older CO2.
There is quite a bit that you can do to help your results last longer. Eat a good diet and avoid environmental stresses such as smoking and excessive UV radiation. Use good products on your skin:
- Vitamin C (morning)
- Zinc Oxide and Titanium Dioxide sunscreen (morning)
- Emollient tretinoin AKA Renova (night)
These habits alone will likely help you keep your results for many years after your procedure.
