Are you sure that acne medicine is working?
<|assistant|>
It is important to give the medication enough time to work. If you are certain you are taking it correctly and following your doctor's instructions, you should see an improvement within four to eight weeks. If your acne has not improved after eight weeks, you should visit your doctor to discuss further options.
