Hi im wondering if anyone can help me, I finished my isotretinoin course around 3 months ago and I'm still stuck with red marks from past breakouts, I still get one or two actives every so often but nothing to what it once was.

im need some advice on what to do for the pie/pih I'm currently dealing with, I have been using some zinc and niacinamide serum along with some vitamin c but it's not really doing much. I'll attach some photos if I can, they look quite red as I've just showered
