How to tell why i breakout in acne on my face? is it from my lotion or what i eat or what?

Minor mystery: You'll never figure out why you get worse acne than peers. Ignore anybody who offers to explain -- it's not helpful. Diet is minimally correlated with acne and the link with dairy is actually stronger than chocolate. You can omit your lotion and instead use topical benzoyl peroxide as tolerated. It's not fun but it gives you an even chance of clearing your face. If you need more, ask your dr.
