Thanks for writing to health care magic.
White patches occur commonly on babies. Even though there are several causes for white patches most common cause is what is called pityriasis alba
. Not to worry regarding the complicated name. These patches require no treatment and subside on their own. Application of moisturising lotion or oil like coconut oil may help.
If the problem persists some of the doctors prescribe low dose steroid
for local application.
