How old is the baby?
The brown mark looks like skin pigmentation. It may be a birthmark.
Not sure about the red mark near to the brownish one.
If you are concerned about anything about your baby, it would be a good idea to see your doctor to check the baby out.
I would not apply any cream on the baby's face or anywhere (apart from diaper rash cream on the bottom) without a doctor instruction.
Best wishes.
Looks like yeast infection, Tinea versicolor,- though uncommon in children. Generally respond to canesten creme.Do consult your Doc.
