Hi and welcome to HCM
Since you do not have active acne now, you can concentrate on the scar treatment.
You can use a facewash such as AHAglow/
glycolic acid or a
salicylic acid face wash daily to reduce oiliness and help with scars. You may use it only at night if you find it too drying. Keep cleansing wipes with you during the day and use when oily or use an oil control facewash when required. Dont scrub the skin or be harsh.
On the dark spots you can use lightening gel(avoid creams) such as kojivit.
You can also
consult dermatologist regarding treatments like
chemical peels, lasers etc to lighten the scars.
As for the pores and deeper scars, best option is to go in for simple
surgical treatment for which the dermatologist can assess and advise you, either for
dermaroller dermabrasion, scar surgery, lasers and newer techniques depending on your requirement.
If you are still getting pimples, it would be better to wait before doing other procedures.
Use a gel based sunscreen to prevent more pigmentation. Never pick on pimples, or burst them.
Continue this treatment and consult the dermatologist as advised for scars.
