Originally Answered: Baby Acne and ways to help?
Overall, make sure your child is clean and dry but don't worry about oil...babies don't have excess oil. Their acne is caused by inflammation, which was initially caused by hormones!
Acne is inflammation and inflammation is worsened by a lot of the chemicals in a surprising number of common baby bath products, including common powders. Powder is unnecessary here.
I would go for a brand called California Baby Super Sensitive soap. It's the simplest, non-chemical soap you can buy. Do NOT use creams except maybe Weleda calendula cream on her body.
My son had this. I simply massaged him with Evening Primrose Oil, which I warmed in my palms, after light bathing. It helped dramatically. Contrary to what you think, a little oil, especially primrose, is good.
Get a bath filter ("bath ball") online if you can. That will take away the irritating chlorine. Or, simply sponge bath your baby with filtered water. And keep her day, keep formula off her face. The problem will go away soon!
