Does Retin-A make acne worse in the beginning?

A lot of people seem to say that acne gets worse not better at the beginning of treatment with Retin-A? But does it really get worse, or is it just that it doesn't actually have a beneficial effect for acne until after a while? I've started treatment and otherwise I am having minimal side effects but I am wondering if using more frequently will cause an increase in acne.
