Wow...No, that doesn't look like acne. Have you ever seen an allergist? This may sound strange, but when my brother (he's now 46) was around 2 years old, he was allergic to cow's milk. He wouldn't get hives...instead the next day or so, he would break out with these huge, red, pus-filled lesions on his lower back. She said they were awful. This looks like what she was describing. I'm thinking this could be an allergic reaction, and maybe even to something you are eating, rather than something topical. It may be worth checking into. Good luck.
