Photodynamic Therapy After Fraxel Laser?

One should expect to have some post-inflammatory redness and sometimes pigmentation after fractionated laser resurfacing such as the old Fraxel or Fractional CO2 Laser. You should wait until the post-inflammatory redness or pigmentation has faded almost completely before PDT. That usually takes at least 2-3 weeks.

Usually 3 -4 weeks is a good time frame to wait to give your skin the possibility to regenerate. The combination of both treatments may add benefit to treat actinic keratoses.
