Is this demarcation? (Photos)

agressive co2 resurfacing can take 6-12 weeks to heal.  I suggest sun protection, photodynamic therapy, and skin care at this time. Best, Dr. Emer.

Thank you for your question madisonaidan. I
am sorry to hear about your situation. Fractional CO2 laser resurfacing is an
outstanding treatment that can address multiple aspects of aging in a single
treatment. Redness can last several weeks after a treatment. We treat redness with IPL approximately four weeks after a treatment. I feather the edges to avoid areas of demarcation. This means using lighter settings around the edges to blend in the treated area with the adjacent untreated area. Please consult with a doctor for specific recommendations.
Good luck!

Co2 laser resurfacing can take months to heal completely, therefore, at this time, it is too soon to know if there will be a demarcation line.  The area treated is obvious because it is so red, however, redness means you are still healing and making new collagen (which is a good thing).  The best way to cover redness after an aggressive procedure such as CO2 laser or a phenol peel is green based makeup or powder.  I would recommend seeing the provider who performed this laser to discuss your healing process.  Good luck!
