my baby has very sensitive skin. she's been having alot of little white spots all over her body. once i applied baby oil (just 2 drops for whole body) and she started have heat rash-like spots on the areas that i applied the baby oil. on her face, around the eye brow area, she is starting to develop some kind of crusts that starts out initially as orange and then slowly progress to dark green.

anyone experience such before? where should i go to seek treatment? or should it be any concern at all?
