I just started using Proactive; are there any side effects I should be aware of like dry skin?

I used to use ProActiv before I got pregnant and the only side effect that I experienced was very dry skin. So instead of using the ProActiv lotion, I used "the Body shop Vitamin C lotion" and I absolutely love that stuff. It somehow will reduce the redness of blemishes, it's oil-free and it has a sunscreen in it.
