“Which SPF gives the best sunburn protection?”

Waterproof sweat proof SPF 50. Unless you’re going to use a complete sunblock which is zinc. That I would not suggest because it is a complete block doesn’t allow things to get through or ultraviolet light, and when you’re not wearing it you burn. Not only as a physician but I was an ocean lifeguard for 10 years, a beach volleyball player, and surfer for over 35 years. If you want to go generic with a name brand, Coppertone children’s formula no tears, SPF 50 sweat proof waterproof reapply every 20 minutes. And if you use a towel and dry off reapply again. Thank you for asking and I hope our sub service
