Will Redness After Photodynamic Therapy Resolve on Its Own?

The reaction from PDT can vary from patient to patient. The redness typically will resolve on its own. In your case, this severe reaction could mean that it will take a few more months for the redness to resolve completely. On the bright side, one benefit of such an intense reaction is could be the improvement of any age-related wrinkles.

You are experiencing what we call post-inflammatory erythema after a photodynamic therapy (PDT). 6 weeks a bit longer than usual. You should see a board-certified dermatologist and consider low-dose anti-inflammatory antibiotics and adhere to consistent daily sun protection. Avoid triggers of facial flushing such as caffeine, alcohol, hot beverages, spicy food, and sun exposure. If redness persists for another few weeks, you may want to consider IPL photofacial. Some patients also have had success with OTC Afrin spray (generic okay) on the skin to achieve few hours of temporary redness relief.

Mikemills,

Good question. Usually PDT does not lead to scarring.  If the redness is post-inflammatory it will resolve on its own but it may take several months. If it is due to telangiectasias (small blood vessels) that your skin recruited to the area than you may need pulsed dye laser to make the redness go away.  Your dermatologist should be able to guide you in the right direction, but definitely give it 8 weeks before doing anything.

Good luck
