my having small acne on his forehead and chin area n some area of cheek what to do his skin also becomes dry day by day I m using mama earth moisturizer on his face

A. May Be the product you mentioned is not suiting the face I do not apply anything as of now instead you can start applying atogla cream that would be a better choice .. So either you use that cream otherwise you can consult your skin specialist or a paediatrician ones as they can guide you better over this issue
