Brown dots Post co2 fractional laser- is this normal? (photo)

This is completely normal. Your face is in the process of scabbing. Be sure to keep up with your skin care routine and do not pick the scabs. Soon, they will drop off, revealing your fresh, rejuvenated skin.

I do agree that the appropriate techniques were not used in your treatment. Being that your skin is still healing and without knowing the settings used, it is hard for any expert to determine the end result. Your skin may need further time for those brown spots to turnover. As far as what you can do right now, it's best to stay well hydrated to promote fast recovery and turnover of healthy skin. Avoid sunlight to reduce risks of hyperpigmentation. Keep the skin clean with a gentle cleanser and moisturize the skin with a fragrance-free moisturizer.Best, Dr. Anil Shah

From your photos it appears that your skin is healing well.  The brown spots are dead skin that will eventually flake off.  Your provider should have prepared you for the healing process and explained to you that this would occur.  It is very important that you follow a good skin care regimen at this time to ensure that the skin continues to heal properly and the best outcome is achieved.  You should discuss your concerns with your physician.
