Frankly speaking, just about any birth control pill could potentially affect your fight against acne.  I have used a few of them, because sometimes you develop allergies, suddenly they stop working as well and you can tell by your period, etc.  Basically speaking, the first few months of any birth control pill are going to be unpredictable, and if they result in mood changes for example, it’s not necessarily that you should swear off birth control all together.  It’s that you actually need to try another type entirely. 

It can be very useful and it also prevents acne, ovarian cysts, and endometriosis among other things.  Granted, they can also come with their risks and side effects, especially if you smoke for example.  But this being said, I would advise you to do your research.  The fact is that many birth control pills tend to be different.  So you will come across countless different reactions to the same exact birth control, because every woman is going to react differently. 

I personally would have sworn by Yasmin a few years ago, before developing an allergy.  But this being said, times change, and since then I have been through a few different ones to find one that really worked well for me.  Likewise, many women will go through the same thing.  But once you find one that covers all your needs, I would definitely stick with it.
