you didnt really said what type of IPL you have used , on which area , what type of hairs , what settings on both machines , what was the results on each side .. can you elaborate on that please ?
I did thousands of treatments with an Epilight a long time ago but these were a few different IPLs at settings that were most appropriate for their skin. I would love to use an IPL. There are a lot of advantages to using one. After testing I chose not to because I believe that it does not provide the same level of effectiveness. You are going to have to take that for what it is, my opinion. There really is no value discussing futher what settings, hairs, etc. IPLs can work, if you want to try then do so. Hopefully you will get good results.
