Hi. Greetings. Did your dermatologist day he'll cure it with twenty days of that tablet ??! Did he not ask you to visit him after three or four weeks! Acne is a chronic condition.. It cannot be cured with a single small course of any other medication. However, you'll need to take maintenance medications. Avoid oily food / smoking/ dust and pollution exposure / maintain good diet and fitness regime. Revisit your dermatologist. Further queries may be sent on follow up chat messaging. Hope this helps.
