5 Ways to Stay Safe in the SunDo your own research into sunscreen. Growing concern about certain additives used in sunscreens such as oxybenzone and vitamin A, and the effectiveness of some sunscreens has intensified in recent years. It is recommended that you do some online research to satisfy your own concerns before purchasing a sunscreen, rather than simply purchasing the first sunscreen you find or one that "smells good". Check the SPF level of your sunscreen. The SPF, or "sun protection factor" number, contrary to popular belief, does not signify how strong the SPF is. It tells you how long it will keep you protected theoretically. For example, it is calculated by how many minutes it would normally take for your skin to burn multiplied by the number that tells you how long it should last. If you burn easily though, you should reapply often, say every few hours, or more often. So, if you burn in 10 minutes of sun exposure without any protection, SPF 30 will keep you protected for 300 minutes (in theory!). Moreover, do not fall for a false sense of security that wearing sunscreen (no matter how high its SPF) allows you to stay outdoors without taking other precautions, such as wearing adequate clothing, keeping to the shade and staying out of the sun during the hottest time of the day. Sunscreen is only one factor in your overall approach to protecting yourself in the sun.Keep in mind that SPF is not cumulative. Applying one SPF 15 sunscreen and another SPF 20 sunscreen may give you slightly better coverage, but it does not add up to SPF 35.30+ is adequate for beach and pool use. It is not recommended to use higher SPF formulas because they give a false sense of security in the sun and a higher dose of chemicals on your skin.The word "sunblock" is a misnomer.

Choose a sunscreen because it protects you from the sun; choose a different product for insect repelling.Choose a sunscreen format that suits you. If you dislike wearing sunscreen so much that you don’t wear it, it won’t do you any good. Wearing sunscreen need not be unpleasant, so try different sunscreen brands and styles to find the one(s) that are best suited for you. There is a wide variety of sunscreen formats available and it can be a challenge to know what works best. Some of this will be trial and error; however, it is noted that experts consider the cream format to be the most useful.[1] Some things to bear in mind include:Some daily sunscreens aren’t as gooey or smelly as some of the heavy duty outdoor sport formulations.Some sunscreens come in spray on, roll on, powder and stick formats.
