If You're Susceptible, Prevention Can Be a Matter of Timing
Sometimes, the obvious choice is the best choice. The top tactic for sun rash prevention is reducing sun exposure. Unless you're a vampire, however, it's probably impossible (and undesirable) to avoid sunlight altogether. So, when you must go out, try to limit your time in the sun. It's also best to avoid being exposed to sunlight when it's at its most intense, which is between the hours of 10 a.m. and 4 p.m.
One way to improve your chances of not developing a rash is to get your skin used to the sun by slowly increasing the amount of time you spend outdoors, beginning in the spring and early summer.
Don't forget skin protection when you're outside. This can include wearing light clothing that covers your skin, and applying sunscreen with a sun protection factor (SPF) of at least 15. Sunscreen is most effective when it's applied frequently throughout the day -- even on cloudy days. Because both UVA and UVB rays can damage your skin and cause rashes, you should look for a sunscreen that protects against both. Don't forget sunglasses and sunscreen lip balm for protecting other delicate areas of skin.
