I usually just use breastmilk (if breast feeding) or I will use hydrocortisone cream. Just a little tiny bit goes a long way. It will also clear up on its own if you put nothing on it.
Breastmilk is a cure-all. It help clear up baby acne, scratches, red spots etc and if babys nose is congested squirting some up each nostril help clear them out (better than saline spray)
