Allergic reaction or eczema?!

I’ve taken her in multiple times they just now put a referral in for a dermatologist idk when they will call though. She’s tried 3 different formulas and still spits up a lot. Her skin is so dry and peels constantly I keep her moisturized all the time! Fragrance free everything. And she gets this redness as you see in the photo. Skin feels a bit scaly too. I’m worried she’s allergic but they don’t want me switching her to a hypoallergenic kind. (She’s a 28 weeker premie) has anyone or anyone’s baby looked like this?! Unsure what group to put this in. I just need to feel a little better..
