Enhancing sunscreen efficacy in the ‘real’ world?

Abstract

Sunscreens, used in the prevention of sunburn and skin cancer, have been commercialized since the 1930s. Their utilization is expanding, particularly in response to photoaging and an increase of skin cancer. However, failures occur in sunscreen use because their efficacy depends on the adequacy of application and utilization. This overview documents issues in sunscreen use and also discusses 2007 FDA-proposed rules to offer possible options for enhanced efficacy and communications to the consumer.
