 Hi, I am Dr. Sachit Abraham, consultant dermatologist at Manipal Hospital in Bangalore. Yeah, if your face is clear and flawless, you need not take acne medication. Acne needs to be treated on and off till a certain age. I wouldn't recommend that a person should keep taking acne treatment all continuously. As in when he gets acne, you treat the acne. But the reason why you treat acne is to avoid scars. A person wants to have a nice, smooth skin, wants to feel confident. That is the only reason why we treat acne. He shouldn't have physical or mental scars on the face.
