A member asked:

What causes some off my cystic back acne to turn black after the real pimple is gone? hyper pigmentation?

A doctor has provided 1 answer

Healing: This is post-inflammatory pigmentation. Alec, I am VERY glad that you are on isotretinoin and I trust you're finally being managed properly. Stay the course and you'll get a good result. There's little or nothing to do about the hyperpigmentation or the redness -- it goes healing.
