[Skin concern] Discoloration and constant issues with re-occuring clogged pores after "recovering" from cystic acne

Skin care routine: remove makeup with Garnier Micellar Water, wash with Cerave Renewing SA Cleanser or Cerave Foaming Face Cleanser.

I use Tarte Amazonian Clay foundation but only spot conceal. I try to avoid makeup as much as possible. I dealt with a random period of cystic acne when I turned 18 that lasted about 9 months. The cystic acne went away on it's own but I still struggle (almost 2 years later) with CONSTANT re-occuring clogged pores that turn into closed comedones. I am guilty of picking at them and whenever I squeeze them a hard sebum "seed" comes out. It seems like my sebum is really thick or gets stuck in my pores and hardens instead of flowing out like it normally should. I am vegan and am really good about not touching my face with dirty hands, not using dirty makeup brushes, washing my pillow cases, etc.

Over the summer I stopped wearing foundation and never got super sweaty and I still woke up each day with really bad clogged pores and closed comedones. I have no idea what to do about this. All throughout middle school high school my skin was fine. I'm almost 20 and my skin has caused me to become depressed and avoidant of social situations.
