I live in Los Angeles, not far from the beach, and I'm very active year-round: marathons, running along The Strand, beach volleyball, surfing, rollerblading, etc. I've used this product for years and it has never failed me yet. I sweat A LOT, and thus reapply every few hours. I visited the dermatologist today, and he commented that despite a lifetime spent outside in Los Angeles, I don't look anywhere near my age and have very little sun damage. I think daily use of sunscreens - for sports, and for everyday under makeup has contributed to this. It dismays me, however, to hear Neutrogena has chosen to discontinue this fab product; I hope they replace it with another high-performance facial sport sunscreen. In the meantime, I'm stocking up on multiple tubes.
