Help!!! Baby acne?!!!!

Alexis • 23. Happily Married to my Soul mate for 4 years & Mom to a baby boy & expecting bby #2

My son is 4 weeks 3 days and he’s had this flare up for about a week and a half! Everyone keeps saying it’s baby acne but I feel like it’s some sort of hives or allergic reaction to what...I don’t know but FTM here should I be worried and how can I clear this up? Thank you

**update

It’s just baby acne according to the doctor! Better safe than sorry, it just looked severe to me. Thanks for the comments and help ladies
