Verdict
If you are acne-prone, granola bar is the better pick of the two. A 21-point gap is the kind of swap that can show up in your skin within a week or two.
Not medical advice. Both scores are for the food on its own. What you eat with it changes the result, and breakouts usually show up 3 to 7 days after a meal. Diet is one factor among many.
