Your type of acne looks too severe and inflamed to be helped by any of these means. Your acne is very severe in my opinion and inflammatory! Please go to a dermatologist for real treatment.
Acne is genetic disease don't forget and it's not necessarily going to completely clear with a flawless lifestyle and diet. In my opinion you need professional help otherwise you are going to be permanently disfigured. And believe me, scars do not heal - they are permanent. Macules fade but scars are forever indented.
I agree with this.
Your acne is very much angry, inflammed, cystic, possibly deeper in the dermal layer of skin which would make me think you would benefit from a retinoid- something that would normalize kertanization and skin shedding. Have you looked into something hormonal? Like BC?
To treat the inflammed lesions I would suggest going to a regular doc, not a derm, and just getting a short dosage of antibiotics, maybe then start on a face wash and topical while on the medication. This would help the body overcome the excessive inflammation. I would see then if after the antibiotics finish if your situation improves.
Its pretty much trial of what works and doesn't per person. I have been work nights 3-5 days a week 12 hrs... and my diet is terrible. I eat all the time to stay awake. Diet Dew is my drink of choice over water. I am doing everything wrong in relation to acne yet I have had no change for the 2 months ive been on nights. Thats me.
