Hlo my daughter is 4 yrs old. Her complexion is dull.. kindly suggest me something for her dull complexion

After birth the complexion does change when babies come in contact with environment. Skin Complexion itself is a genetic inheritance and application of any sort of products doesn't change it. Moreover its too early to say that it'll be the final complexion of the baby for the rest of the life. Use mild baby products that shall suit baby's skin.
