What is better-- fractional or non-fractional CO2 laser?

Hi camkon.  The two modalities are used for different purposes, and both are highly effective.  There is shorter recovery times with fractionated treatments--the degree of fractionation can be increased or decreased depending upon skin type, texture, pore size, wrinkling, etc.  Fully ablative laser treatments have longer recovery but may be indicated depending upon the desired result. Be sure to see an experienced, board certified physician to be fully evaluated before proceeding. Best wishes,

Co2 is the type of laser and fractional is the technology.  There are fully ablative Co2 and fractional Co2.  Factional takes less time for healing but gives a little less results than fully ablative.  Co2 is the more aggressive form of lasering as compared to other forms like thulium or erbium.  Both do well in a series of treatments, I suggest a formal consultation with an expert. Best, Dr. Emer.

The current models of C02 can be used in both modes. Choose an experienced and expert board certified physician to perform your treatment.
