The best laser for stimulation of collagen to help skin laxity and lend a plump appearance to the skin is the CO2 laser. To reduce social down time post procedure, with minimal impact on efficacy fractional CO2 treatments are performed. DeepFx affords deep dermal stimulation for collagen synthesis and skin tightening. Fractional CO2 resurfacing is not ideal for all skin types. Darker skin types run the risk of hyperpigmentation or hypopigmentation if not pre-treated appropriately or if the proper post treatment skin care is not instituted.
