Because it's the summer, I've been going to the beach a lot lately. Sometimes I'll go with family or friends, sometimes I'll just go alone. The thing is, I burn pretty easily, so I need to always put sunscreen on. When I'm with others, is isn't a problem to get sunscreen on my back because I can ask them to do it for me. When I'm alone, this is a problem because I don't have the reach or flexibility to do it by myself, and I don't really feel comfortable asking strangers to do it for me.
Is there any easy way to apply sunscreen to my back by myself? I can use either spray sunscreen or a lotion.
Take a spare towel that you can stretch across your back. Apply liberal amounts of sunscreen to the towel. Rub the sunscreen into your back using the pressure of keeping the towel tight across your back. If you have skin folds, you may have to work at getting into the crevices.
If you want to use lotion - put some on the BACK of your hands. You can rub it into your back using the backs of your hands and the top of your forearms. Doing it like this instead of trying to use your hands normally, you won't be trying to twist your wrists in some unnatural way to reach further up into your back. Try it - you'll be surprised how much more natural it feels and how much further you can reach without straining.
Why not ask (politely, of course) for someone to do it ? Actually this is a pretty standard way to engage in a nice conversation or, perhaps, something else, at least here in Brazil.
The trick is to behave naturally. If all you want is the suncreen, then I´d suggest to look for a group of parents/grandparents with kids. Opting for sprays also reduces a lot any chance of being rejected.
Get a hand-held back massager, or a loofah on a stick, or a pancake flipper, or a fly swatter or anything with a long handle and a flat surface. Apply the sunscreen to the flat part and rub it all over your back with the handle. Maximum coverage, no waste and minimum looking-like-a-weirdo!
