to fade them it does take time. But to make sure they wont get any darker make sure you dont get a sunburn! im serious... wear at least spf 30+ everyday. Im sorry im not of much help...

Everyone says Dans AHA works wonders but you can't use it till you're done accutane.

Apple Cider Vinegar twice a day applied with a cotton bud. Cheap, but effective in my opinion.

I've moved this topic to the Scars and Red Marks Thread

After you complete your accutane course use Differin cream 0.1% (Adapalene) this will help fade your hyperpigmentation and becuase you are on accutane I think your skin has adapted to retinoids so Differin wont do any major irriations <3

Apple Cider Vinegar diluted 50/50 ACV/Water and then upping it 70/30 after your skin is accustomed to it works wonders. But it took a little over 1 month for me to notice any effects. After 3 months of using it I noticed quite the improvement. (You may hear 3 months and think that's a long time but in the past I have left PIH untreated and it took 1 - 2 years for it go away by itself)

I too have researched this forum and heard DAN's AHA+ is a great product for red marks. I purchased a bottle 2 weeks ago and giving that a trial run
