Acne (pigmentation)

Any tips to speed up the lightening process of my dark marks? I use apple cinder vinegar as a toner and twice a week an AHA & enzymes peeling mask. However more acne comes while old acne marks fade and I have to deal with the new ones all over again. It’s just an endless process I want to get rid of but can’t. I had a chemical peel two weeks ago and it was a fail. I just got new pimples which formed new pigmentation and thus this result:

(Excuse the weird face 😂)

So, because I’m sure I’m gonna get this comment, no, I don’t pick as much as it looks like. I do sometimes pick, I won’t lie, however i may have pimples that I won’t touch, and when they’re gone they always leave a dark spot. It’s probably because my acne is cystic and my pimples are too deep in causing more harm. Also my skin is quite sensitive on its own in the sense that if I dry my face with a towel (even gently) at least one pimple will bleed.

Please If you have any tips for me I’d love to try them. It’s just because my confidence has dropped so much because of this, all my friends are clear of acne and I’m the only one left...
