Will my poikilodermia of civatte fade?

You need to gradually increase settings .Another option would be laser for both brown and red color. The q switched yag in the 1064 wavelength targets the brown color and the 532 targets the red coor. 

Unfortunately, Poikiloderma can be a stubborn condition to treat and may require continual maintenance.  IPL is an ideal in office treatment because it targets both pigmentation and vascular activity.  It is not uncommon to start with a series of 6-8 treatments spaced about 3-4 weeks apart, but it can take more.  Having patience can be challenging, so try to remember sun damage develops over time and there just isn't a quick fix.  You can also discuss with your doctor skin care or topical treatments that you can do between treatments that may help accelerate the process.  I hope this helps!
