Sun exposure is a leading rosacea trigger, so here are some tips to help you safely survive the summer sun:

• Find the right sunscreen formula. There are two types of damaging rays: In general, UVA rays age skin; UVB rays burn it. Not all sunscreens protect against both types, so look for non-chemical sunscreens that contain zinc or titanium dioxide and an SPF of 15 or higher.

• Use it early and often. Apply sunscreen liberally (about a shot glass worth for each application) at least 30 minutes before going outdoors and periodically throughout the time spent in the sun. Use it daily whether it's sunny or cloudy.

• Wear a hat. Make sure the hat has a wide brim or visor to shade your face. A sun umbrella might also be a good investment if you plan to be out for an extended time.

• Limit peak exposure. If possible, avoid being in direct sunlight from 10 a.m. to 2 p.m. Plan outdoor activities and exercise for when the sun is not as intense.

• Stay cool. Remember to stay hydrated by taking along a water bottle. Chewing on ice chips also helps, especially with flushing.

• Don't forget your medicine. Be sure to continue your medical therapy as prescribed by your doctor.
