SHOULD I WORRY???

My baby is 4 weeks today & has been getting this “rash” lately all over her face. I know newborns have acne and sometimes get worse around this time but it looks so ugly and I’m just unsure if I really need to worry and call her pediatrician?

* she never cries of pain nor does she have a fever.

Also if you have any recommendations or remedies for it, that would be very helpful.

*Im exclusively breastfeeding if that matters at all?
