Because sun exposure was cited as the most common rosacea trigger by 81 percent of patients responding to a National Rosacea Society survey, it may be important to remember a few things over the summer when sunlight is at its height. Here are some tips for protecting yourself from the sun:

• Avoid the sun as much as possible. Limit the amount of time spent in direct sunlight, especially between the hours of 10 a.m. and 4 p.m., when sun is the strongest.

• Protect your face. Use a sunscreen year round, but especially in the summer. Make sure it has an SPF of 15 or higher and is effective against both UVA and UVB rays.

• Apply sunscreen at least 30 minutes before going outdoors. Apply it liberally and periodically throughout the time spent in the sun.

• Try a pediatric sunscreen. If you have sensitive skin, a pediatric formulation or a hypoallergenic sunscreen may minimize irritation.

• Wear a hat. Make sure the hat has a wide brim or visor. You'll have added protection and may even make a fashion statement.

• Stay cool. Seek the shade as much as possible and remember to stay hydrated by taking along a water bottle. Chewing on ice chips also helps, especially with flushing.

• Don't take a vacation from medical therapy. Be sure to continue your normal cleansing routine as well as the medical therapy prescribed by your doctor.
