Skin allergy/whiteheads issue on face.

Hi My name is Priyanka, actually I was taking TB medicines (Rifampicin and isoniazid tablets) for last 9months for a gland under my left armpit. Recently on Jan 20, 2022, after dr. consultant I stop this TB medicines. But now I am having so much whiteheads (Kil ) on my face may be it's allergy or something else. My face skin is oily. Please suggest something. Right now I am using, adapalene gel adaferin 0.1% on night. And face wash like Cipla Saslic Ds foaming facewash(with Salicylic Acid 2%) on night. Or Ponds charcoal face wash on morning. I am having some acne on back and on chest also. But the face effected badly. Please suggest something best. 🙏 See the attached pics for help. Thank you.
