My other colleagues have answered well and indeed, it appears that there is a cystic lesion underneath and the evidence of discharge suggests you need urgent medical attention.
Steroid injection and antibiotics should probably be the mainstay of the therapy.
In terms of other changes to your skin care, please ensure you are using a light gel based moisturiser in view of the oily skin, and please use the appropriate concentration of rectanyl(and don't be overly generous as what my patients love to do unilaterally).
There is such a thing as overdoing it and leading to excessive peeling and thus removing the natural skin barrier against bacteria entry.
Pls see your doctor early!
