Here's a paper from dermatologists about healthy skin:
"While I recommend using an insect repellent with a 10 percent or lower DEET concentration for children, I do not recommend using a combination sunscreen and insect repellent because the reapplication of the product will increase the percentage of DEET on the skin," said Dr. Johnson. "It also is important to note that insect repellents with DEET should never be used on a baby less than two months old, as their skin is very sensitive. To avoid irritation, I advise everyone to wash off the repellent with soap and water once they come inside."
Atopic dermatitis or eczema is a common condition found in newborns and young children. This itchy, oozing, crusting rash occurs mainly on the face and scalp, but patches can appear anywhere. It is estimated that this condition affects 10 percent of the U.S. infant population. However, in nearly half of these children, the disease will improve greatly by the time they are between five and 15 years of age. Others will have some form of the disease throughout their lives.
