奶癬, my little baby also had the same problem, it got kind of serious before as well. I didn't take him to see any doctor, here is the thing you can do
Clean his face more often, (i cleaned his face every time he finished drinking the milk), clean with warm water (the whole face), and then, put cream on his face to keep his face moisturized, this is extremely important, after 3 days or so, his face got so much better!!!!
keep cleaning, keep putting cream, you baby will be fine very soon.
