Thanks for writing to us.
Antitubercular medicines can lead to eruption of acne. Do not squeeze this lesions as these may then with scarring and pigmentation. Instead use a salicylic or Glycolic acid
based face wash( saslic or AHA glow). Apply clindamycin
gel and adapalene
gel over affected areas. Get your blackheads extracted. Do not use oily products over face instead use mild non comedogenic moisturiser if required. Consult a dermatologist
near by for skin analysis so that if required an oral medication be added for better control.
Hope that helps. Take care
