A new study has documented for the first time the clinical differences between subtype 1 (erythematotelangiectatic) rosacea – characterized by facial redness and, sometimes, visible blood vessels – and a condition with visible blood vessels from sun damage known as telangiectatic photoaging (TP), providing a clear picture of the differences between the two disorders and aiding in appropriate treatment.1
Q. Is it common to break out in an itchy, bumpy rash (always on my forehead) after slight sun exposure? Would sunscreen help prevent this?
A. In patient surveys, the sun ranks as the most common trigger for rosacea flare-ups, so it is likely that the sun is the culprit in your case. Even incidental exposure, such as running errands on a sunny day, might be enough to cause an outbreak of rosacea symptoms in some individuals.
Sun exposure is a leading rosacea trigger, so here are some tips to help you to safely survive the spring and 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.
Although sun exposure may be the most common rosacea trigger, patients who take steps to protect their skin when outdoors have been successful in reducing rosacea outbreaks, according to a new National Rosacea Society patient survey. Virtually all of the 739 respondents said they make an effort to shield their skin from the sun, and 88 percent of those said their efforts had been successful or somewhat successful in reducing their rosacea flare-ups.
A. Because sun exposure is a leading flare-up trigger for so many, using sunscreen with an SPF (sun-protection factor) of 15 or higher is recommended for most rosacea patients all year-round -- but it is also important to avoid direct sunlight as much as possible.
A. In a National Rosacea Society (NRS) patient survey, sun exposure ranked as one of the most common rosacea triggers. At the same time, the American Academy of Dermatology (AAD) has conducted a public awareness campaign to warn against the dangers of indoor tanning.
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.
A poster presented at a recent meeting of the American Academy of Dermatology by Dr. Ronald Marks, professor emeritus at the University of Wales, raised the question of whether subtype 1 (erythematotelangiectatic) rosacea can be distinguished from sun-damaged skin.
Dr. Marks observed that patients with sun-damaged skin often exhibit facial redness and visible blood vessels, which are also symptomatic of subtype 1 rosacea.
While many are aware that protection from sunlight is important to prevent skin cancer, rosacea patients have even further reason to minimize their exposure. In fact, beyond being the top trigger for rosacea flare-ups named by 81 percent of patients in a National Rosacea Society survey, researchers have found that sun exposure may be linked to the visible blood vessels (telangiectasia) often associated with rosacea.
Sure, you'll suspend your mail delivery and find a pet sitter, but you should also be sure to plan your trip with rosacea in mind. Depending on your individual sensitivities, the following suggestions can help lead to a much more enjoyable getaway.
