im takin pills for my face and on the bottle it say "may decrease the effectiveness of bvirth control pills" what do they mean by that ?
It means if you're on the pill you need to be using another backup method, because the pill might not be doing it's just properly. Some medications interfere with a pill's effectiveness.

antibiotics are notorious for reducing the effectiveness of the pill. you should definitely use a backup method while on your medication.
