Hello started treatment on my cheeks jaw and forehead with Pacato cream 1.015% per my dermatologist. After second treatment all treated areas red blister covered. A picture of mild to severe reactions was provided and I would say I m extreme severe. Now my dermatologist wants me to complete the application with the third tube and I am very apprehensive. It s very expensive and I don t know what to do she is persistent on using last application. Male 54 years old diagnosis was actinic keratosis.
