no multivitamins will not cause acne. the most common cause of acne is your own hormones. they most definitely will. i think it has to do with the biotin in my multivitamin. before my multivitamin i started taking biotin to think it would make my hair and nails longer and my face glow. boy was i wrong! i've never had such bad acne in my life - to the point of cystic acne! it was embarrassing and painful! happy to say that as soon as i stopped taking it my face returned to normal and i was never so pleased with my own skin before! a couple months later (i completely forgot about the biotin incident) my mother mentioned how i should take a multivitamin since i'm a vegetarian and don't get all the nutrients i need. so silly me - "yeah sure mom grab a bottle for me! it'll be great! " i didn't even look at the label and about 2-3 weeks into taking half a pill every-other day i started to break out like crazy on the left side of my face mostly my cheek. at first i thought it was due to stress but no way it was because of the multivitamin. i also researched it some b vitamins and iodine are two other big causes of acne. "grrrreat their all bundled up in the little capsule to destroy my face! " moral of the story be weary multivitamins sound appealing but can be toxic (even in small doses)! no. multivitamin does not cause acne.
