EltaMD UV Sport

Its hybrid formula—Zinc Oxide 9%, Octinoxate 7.5%, and Octisalate 5%—provides a transparent, matte finish that is fragrance-free and hypoallergenic, earning a stronger sensitive-skin rating than any chemical-only option. The zinc component enables immediate protection, eliminating the 20-minute activation wait required by Coppertone Sport. At $32.00 for 3 fl oz ($10.67 per ounce), it is nearly ten times the cost-per-ounce of Banana Boat and 1.8 times that of La Roche-Posay. However, Octinoxate 7.5% triggers a reef safety fails under Hawaii Act 104, scoring 30—the lowest in the field. Athletes in reef-proximate waters should choose any other option; those valuing clinical endorsement and drench-proof texture will find its performance uncompromising.
