Rash 4 Weeks Post Microablative Co2 Fractional Laser Treatment

There can be a number of reasons to develop a "rash" after skin resurfacing.  This may be related to occlusion (blockage) of the pores by topical products, hypersensitivity to products, or more rarely infection.  Your doctor should be able to help you sort through these possibilities.

There are many reasons for developing a rash after fractional co2. First of all, thick moisturizers like Aquaphor will block up pores and cause acneiform papules throughout the face. This is why at day #4, I have all my patients switch to cetaphil lotion. In addition, I tell all my patients not to use any creams, sunscreens, etc. on their face for the first 7 days because an allergic reaction may occur. There is also a possibly of an infection. I would do vinegar soaks twice daily and everyone starts on antibiotics and antiviral one day prior to procedure and continues for 8 days. You should definitely go back and see your doctor.
