Hello doctor,My four year old son has a one-inch dry scaly pink (sometimes red) patch next to the corner of his mouth. He is healthy. He uses hypoallergenic sunscreen at his camps. It has been five weeks and it is not getting better. He does not have a history of eczema, etc. It does not itch or hurt. I read a lot about perioral dermatitis and other things. I started Clotrimazole cream four days ago. It is less red and just pink, but dry and scaly still. It is not getting bigger and there are no pimples or crusting. I do not want to give him oral antibiotics. What should I do? Should I try Metrogel? What is it?
Hello. I have seen your query and concern. Revert with more information to a dermatologist online -->
