 Hi, I am Dr. Sachit Abraham, consultant dermatologist at Manipal Hospital in Bangalore. There are different treatments for acne. One is, like I said before, acne is caused by a bacteria. It's called propionibacterium. So there is an antibiotic called tetracycline which kills the bacteria that produces acne. So once you give the antibiotic, things get better. There are certain, if it is like severe grade 4 acne, like nodular acne, there are much more stronger medicines like isotretinoid, which has to be taken under the prescription of your dermatologist. So, and then there are peels, chemical peels to cure scars, microdermabrasion, dermarola. These are all different treatments, but one has to go under the care of a dermatologist. Now and then, acne comes till at 25 plus or minus 2-3 years. And when acne stops coming, a person needs to have nice smooth skin, flawless skin. That is the idea of treating acne. So acne has to be treated as a man required till a certain age.
