The best offense against a common skin problem such as rosacea is a strong defense, according to Charla Krupp, noted beauty expert and best-selling author, in offering some "makeup makeover" tips and other advice to help rosacea sufferers look their best.

One of the first and most important steps a rosacea patient should take is to ask his or her dermatologist for help in formulating a skin-care plan as early in treatment as possible, Ms. Krupp said. "The average woman spends $100 on beauty products each month, and trial and error is just too expensive."

Facial cleansers and makeup often contain additives such as fragrances, peppermint and alcohol, which are frequently cited as rosacea triggers, she said. "But there are plenty of products without these ingredients, so make sure to read the labels before primping."

A variety of makeup brands offer products with a green tint that can help counteract the appearance of redness, Ms. Krupp said. She suggested using gel or cream makeup formulations to create a  dewy  look that hides blemishes and wrinkles.

Because many rosacea patients suffer from eye irritation or extremely sensitive skin, Ms. Krupp recommended using eye pencils instead of liquid eyeliner and water-based mascara instead of waterproof mascara for easier removal.

Makeup brushes that are cleaned frequently are a better choice than sponge applicators, and replacing makeup every three to six months will also minimize contaminants, she said.

Ms. Krupp noted that clothing can also play a role in helping rosacea patients optimize their appearance. She advised choosing "red-reducing" colors such as yellows and blues and avoiding red, white and black, all of which emphasize a red face. In addition, she emphasized the benefits of long scarves, which can serve double duty as both a fashion accessory and a shield against the wind on wintry days.

A "bad skin day" doesn't have to turn into a disaster, Ms. Krupp said. "If you have a flare-up despite your commitment to following a rosacea-friendly routine, get over it and treat yourself. I recommend a manicure or pedicure, a massage or even buying a new top."
