An appraisal of the efficacy and substantivity of the new high-potency sunscreens - 07/10/17

Several recently introduced sunscreens were evaluated using test procedures proposed by the Food and Drug Administration. The newer sunscreens proved to be highly protective, possessing Sun Protection Factors (SPF) of 15 or greater.
