Fractional CO2 Laser is the best treatment if you want maximum results from one treatment. If you can afford to take some time (7-14 days) to heal, then doing this treatment is like having multiple other non-invasive treatments at the same time. It is also the best monotherapy for advanced skin damage and wrinkles.
CO2 laser technology does not damage the skin, so there is no scarring, which means less chance of infection and faster healing time.
