I am an 18-year-old boy with severe acne, nodular cystic acne, and acne vulgaris. I tried everything, but nothing really worked. So, two months back, I finally decided to visit a dermatologist. The dermatologist prescribed me Isotretinoin capsules or Sotret of 20 mg. So, it was working quite well, but I had some breakouts. So, on my next follow-up, she added 10 mg more. And today, after six weeks, I had another follow-up. My previous doctor is on maternity leave. So, I had to meet another doctor. The new doctor decreased my dosage by 10 mg, and now I am supposed to be taking 20 mg per day. The doctor I visited today suggested going through some acidic treatments like Salicylic acids. She said taking medicines would not get me the desired skin and I should be doing these acid treatments. So, what I want to know is: Is acid treatment necessary? My acne is fading away, but there are some new breakouts that I think are due to my own carelessness. I eat oily food, sleep very less, and do not drink enough water.
