Fully ablative laser treatment or conventional CO2 laser resurfacing, as it is termed by the medical community, is hardly practised these days. This is because the procedure is associated with a significant risk of a permanent colour mismatch from the irreversible destruction of pigment forming cells residing in the top layer of the skin as well as the risk of hypertrophic scarring.
Practically all laser surgeons have migrated to the fractional approach which gives equivalent results albeit with several treatment sessions rather than a single session.
It will be good that you see your preferred Aesthetic doctor for an assessment of your condition and a thorough discussion of which is the best procedure that balances results with safety.
