I know this topic has been covered before, but many of the threads are old and there may be some new/improved products on the market that I'm not aware of. Going to Isla in June, and it's going to be hot, hot, sweaty-hot-hot. Hubby loves to tan, but I prefer to protect my skin (actually I'm tattooed and am not about to let the sun ruin my ink investment!). At home I wear an SPF 50 but it's rather greasy. I don't know if I can stand that greasy feeling on my skin while I'm already melting due to the heat. I need something that is very sweat resistant. Just wondering if any of you have a favorite that you wouldn't leave home without.
