The Children and Suncreen Study

Archives of Dermatology

Childhood sun exposure is thought to be a key risk factor for future skin cancer development. Often used as a stand-alone primary prevention method, sunscreen is the most common form of sun protection used by children. Because there is a linear relationship between the thickness of sunscreen application and the sun protection factor (SPF), sunscreens may have an effectively lower SPF if applied in inadequate amounts. In this crossover study of children's use of 3 sunscreen dispenser types, Diaz et al demonstrate that children applied significantly more sunscreen when using a pump and a squeeze bottle compared with a roll-on. All sunscreens were applied at substantially less than the recommended thickness.
