question: Hello doctor,I am an 18 year old boy with severe acne, nodular cystic acne, 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 was having 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 me to go through some acidic treatments like Salicylic acids. She said taking medicines will not get me the desired skin and I should be doing these acid treatments. So, what I want to know is: Is the acid treatment necessary? My acne is fading away but there are some new breakouts which I think is due to my own carelessness. I eat oily food, sleep very less and do not drink enough water.
