Which IPL laser is most effective in treating poikiloderma?

Thank you for your question. To help you understand, there is a big difference between IPL - Intense Pulsed Light therapy and a Laser therapy. IPL devices put out light energy with many wavelengths while lasers usually provide only one wavelength. Typically, IPL recover periods are less than laser treatments. Patients often require a series IPL treatments. In my experience, most patients prefer IPL treatments for your condition. IPL does a great job at simultaneously improving unwanted redness and brown. It can also improve skin contour. While technology is always improving, I have had excellent results using IPL devices made by many manufactures - Syneron, Lumenis, ESC, InMode, etc. So it is more about the operator vs. the device. The attached reference can show you the results with IPL. 

Poikiloderma  is best treated with lower wavelength intense pulsed light. Most IPL systems have a handpiece or filter for skin rejuvenation/vascular/pigment.   The Cynosure maxG system is very effective,  but many other systems will be effective as well. 

 Best wishes 

I like yellow laser, excel v or pulsed dye/vbeam laser to treat this over IPL.  See an expert for options.  Best, Dr. Emer.
