Sunblock and sweat. No longer enemies on court.
Neutrogena has just come out with Wet Skin Sunblock Spray. Spray it on over wet (sweaty) skin and it cuts right through to form a UVA/UVB sun protective barrier. Use it during play when you need to reapply. The spray will keep your hands from getting slick.
Sweatproof, waterproof, oil and PABA free. It runs $9 -$11 (higher SPFs cost more). In theory, because it’s sweatproof, you shouldn’t have to reapply but “sweatproof” doesn’t take into account regular toweling or dripping mega sweaters. Better safe than burned.
