This! I have always had clear skin. But once 36 hit I started getting those super deep and painful pimples (cystic acne?). It would just be one, but it would takes weeks to resolve, then leave an ugly red mark for MONTHS. As soon as the dark spot mostly faded, another painful pimple would start again. I felt like I was always in this cycle of having a painful pimple or faded the mark it left behind.
Tretinoin plus azelic acid did the trick. I haven’t had a pimple in years!
