<s>[INST] Hello doctor, I am a 20-year-old boy with a face full of acne scars. I have it for the last two years. I have tried many home remedies but did not consult a doctor. They got cured to some extent in the last two to three months or so but have now started reappearing. I want a permanent cure without any medication. Please help. [/INST] Hello. Nowadays, acne is considered physiological and a natural phenomenon rather pathological. Around 95% of the world population would have acne at some point in life.  Getting into your case, you are 20 years old, it is the active age of acne. It starts at teenage around 13 and lasts until 30 years of age. No one can cure acne with medication. So it is very remote possibility that it gets cured without medication. Acne can be controlled, but cannot be cured. Acne is due to overactive oil-producing glands present in the skin called sebaceous glands. In order to cure it, all oil-producing glands need to be removed which is impossible. There are also hormonal and genetic factors involved in it. There are very few effective medications available for acne which can control the recurrence of acne. Medications depend on the grade of your acne. I cannot prescribe you medicine without seeing your clinical picture or in person. However, I would like to give you some skin care tips to keep your skin healthy. I would suggest you get back to me with your clinical picture so that I can prescribe you medicines or you can consult your dermatologist for treatment.
