Recently I've been painting my face every other day (at night) with Lugol's 2% iodine. I put some in a cup, soak it up with a cotton ball, and then paint my face. I had really deep scars on my cheeks and it has seem to have really cleared them up, it's almost completely smooth. Has been also helping with my acne. Not sure if you've tried Iodine painting.
I also use Pure Body Naturals Dead Sea Mask a couple times a week. Not sure if that has been helping with my scars too, but I figured I'd mention it just in case you wanted to try that too.
100% the Iodine has totally been helping though. I posted a question on here recently about how often is too often to paint your face with iodine, but no one has answered yet :/ So far I've had absolutely no problems, only awesome results. I have low platelets so any cut, scar, bruise, you name it, takes a million years for it to go away. I'm so surprised that the Iodine has been giving me such great results. Hopefully you haven't tried this yet, and it helps, if not, I hope you find your solution! **Wishing you luck**
