Allergic reaction or milia?? Need an esthetician’s help!

Britt

Okay so I’m freaking out about all of these little bumps that like appeared over night. They don’t itch or anything. I started using Olays night cream recently, I’ve probably used it about 4 times now. Would that cause this?? I’ve always had a couple milia spots but not like this. Do you think this is a reaction or milia? And will it go away?! Is there anything I can do to reduce this?
