Two months isn't going to be very helpful in the long run. Continue with your course and you will be much less likely to have your acne return.

Ask your derm!

I would imagine that you continue - just because you are not getting new pimples now doesn't mean you won't get them in a few months time if i was you i would complete the full course and when you are off the pills you will hopefully notice that marks will fade...

Agreed with all the above posters. You need to do a full course at the correct dosage to increase your chances of remission. Remember that acne can take a while to form under the skin so just because you don't see it, doesn't means its not there.

Speak to your derm though and ask.
