Review title is A magnificent sunscreen in every other way! [SEP] This is a review by Oscar Jaeger, Lois's husband. All four of this sunscreen's active ingredients – Octinoxate, 7.0%; Benzophenone-3 (Oxbenzone), 5%; Octocylene, 4.0%; and Avobenzone, 3.0% – are toxic to coral reefs and of questionable safety to human beings.
