One of the biggest daily challenges for rosacea sufferers is keeping their facial redness in check. Here are some ways you can tone down rosacea redness.

• Try camouflaging makeup. There are several green-tinted foundations, concealer sticks and even green-tinted moisturizers on the market. The green color helps counter the red appearance, and can be used under other skin-tone foundations.

Medical researchers reviewed scientific progress in understanding the potential causes and other aspects of rosacea during a recent research workshop conducted by the National Rosacea Society. The well-attended session was held during the annual meeting of the Society for Investigative Dermatology to stimulate further rosacea research and broaden awareness of research grants now available from the National Rosacea Society.

Red was not a new color to Kathleen Shoup. Her fair Irish complexion had blushed and flushed most of her life. But then as a roller dance skater, her cheeks began to look particularly red hot.

It was after she started skating competitively at the age of 48 that Shoup noticed her redness was worse. "My long workouts caused red blotches and they took longer to go away than before," she said. "I finally went to the dermatologist because I had a bad rash across my face," she added. The dermatologist diagnosed the rash as rosacea.

Severe rosacea symptoms often have a substantial impact on people's work lives, according to a new survey by the National Rosacea Society.

In the survey of more than 700 rosacea patients, 66 percent of those with severe symptoms said rosacea had affected their professional interactions, and 33 percent had cancelled or postponed business meetings because of their appearance. Twenty-eight percent said they had missed work because of their condition, and 28 percent also said it may even have influenced their being chosen for a new job or promotion.

Q. I've been using medication for some time now and it has cleared my pimples and reduced my redness, but it also seems to have made me develop more spider veins. What's going on?

While rosacea has sometimes been described as affecting adults between the ages of 30 and 50, in actuality it may be just as common and even more severe after age 50.
