Is This Acne?

So my daughter has had this break out on her forehead for years now. Since she was an avid soccer player, I thought that it must be from her bangs and sweat, causing bacteria. I have always prescribed her salicylic acid and followed acne protocols. However, after I became an acne expert, I realized this wasn't acne at all - and bacteria isn't what causes acne! Now she is on this program and getting clear, finally!
