Fractional CO2 Laser Treatment Limits?

When you go for a factional laser treatment, your doctor or technician should let you know what you can expect in terms both the treatment and the post-treatment downtime and results. The full effect of the fractional treatment occurs three to four months after your treatment. The full effect of the collagen simulation is visible at this point.

You may do more than one treatment for a given area for harder-to-fix problems, or more sensitive regions. For example icepick acne scars may be treated 3 to 5 times with treatments 2-4 weeks apart. Another example would be treating strechmarks 3 times with a similar protocol for better results.

After completing the right number of treatments with the right intensity for your given situation, we recommend touchups every 3 to 4 years. The idea for undergoing Fractional Laser treatment(s) is to stimulate the collagen so you don’t need repetitive treatments. All this information should be covered in your consultation.


At the Victoria Park Medispa, we take off the doctor consultation fee from any appointment booked and offer complimentary consultations with our technicians, therefore reducing a client’s risk of having a treatment performed without taking the time to think about what they really want. Any esthetic tool needs to be in the right hands, to achieve the best possible results.

The answer depends on the reason you were having the laser treatment done in the first place, but as long as safe practices were employed and enough healing took place between treatments you can definitely have multiple treatments.  The results are additive to some degree, but unpredictably.  You may get your biggest improvement after one or after 3 treatments for instance, but it is unpredicable.  However, at some point, the improvement begins to level off and thus you experience what I tell patients: The Law of Diminshed Returns.  When that will be for you or me is uncertain.  

I hope this helps.
