Scarring After CO2 Fractional Laser Treatment

Thank you for your question. CO2 is used to tighten the skin and reduce pigmentation. it is recommended to pretreat with a topical hydroquinone to prevent hypopigmentation.

Fractional ablation may cause your skin to have scattered scars.  These are likely due to the ablation + swelling. I would begin pulsed dye laser treatments to improve your scars. Best, Dr. Karamanoukian 

Thank you for your question.
I agree that the sponge effect you noticed is probably due to the swelling, but it is hard to say without a picture or consultation.
If you are worried, you should definitively go back to your doctor or ask for a new consultation with a Board Certified Plasctic Surgeon or Dermatologist.

The appearance of your skin is most likely due to persistent swelling.  Having stated this I hope you have returned to your surgeon with these concerns.
