Dermatologist's most frequently asked questions

If you experience redness or facial flushing, you’re in good company. Up to 10% of Australian women have the condition. The other thing you should know? It can affect anyone—not just Celtic skin types. “Blushing is triggered by all sorts of stimulus,” explains dermatologist Dr Adrian Lim. “Just a drop of alcohol or hot coffee—even things like emotional stress—can set off an attack.” In the past it’s been difficult to control, he admits, but a new cream called Mirvaso (available in Australia later this year) could change that. So how does it work? “It shrinks the blood vessels for around 12 hours,” Dr Lim says. “Apply it in the morning and it will last all day.” Ask your doctor whether it’s right for you. In the meantime, Rozex may help with rosacea (it’s available by prescription) or try over-the-counter creams such as Azclear Action Medicated Lotion ($12.99, Ego Pharm) or First Aid Beauty Anti-Redness Serum ($36, First Aid Beauty).

In a word? “Yes, but only a few ingredients have good scientific evidence supporting their anti-ageing claims,” according to dermatologist Dr Michelle Hunt. Top of the list is broad-spectrum sun protection. “Sunscreen is most important in Australia since UVA rays [which account for 95% of UV radiation] are the main cause of skin cancer and skin ageing,” she explains. Next, try topical tretinoin, a prescription-only vitamin A derivative. “This regulates cell turnover, traps free radicals and stimulates the production of new collagen.” Over time, patients notice smoother skin and fewer lines. But it’s not for everyone. Sensitive skin requires diluted, less irritating forms of vitamin A, which can be found in over-the-counter treatments such as Environ AVST Cream 1-5 ($82-$108, Environ). In addition, ingredients like antioxidants, peptides, botanicals and growth factors “show a lot of promise” says Dr Hunt. Try LifeCell Collagen Booster ($55, LifeCell) for a hit of resveratrol, one of nature’s most potent antioxidants. Related: 14 anti-ageing superfoods.

Noticed scaly patches on your arms or legs? Hot showers could be to blame. “When we feel cold, we stand under steaming hot water to warm up—and that’s not a great idea,” says dermatologist and Prevention advisor Dr Stephen Shumack. “Think of vegetable oil spilled on the bench. It won’t come clean with a cold, wet sponge. Only a hot one will do the job, and that’s just what near-boiling water does to our skin’s natural oils. It removes them,” he says. And if you already suffer from dry skin, this will only inflame the problem. The solution? Reduce the frequency, temperature and length of your showers. The body wash you use can also contribute to dryness, so switch to a mild formula such as Bioderma Atoderm PP Foaming Gel ($34.95, Bioderma). Afterwards, while skin is still damp, seal in moisture with a product like Aveeno Skin Relief Moisturising Cream ($14.95, Aveeno). And as for keeping warm? Layer on those woollens—your skin will appreciate it. Related: Superfoods for superskin.

The short answer? Yes. The new fractional lasers are much less invasive than lasers of the past, and present fewer risks, says Dr Hunt. “Instead of stripping off the entire skin surface, these lasers (such as Fraxel) create microscopic holes through the top two layers of skin and leave surrounding islands of tissue undamaged,” she says. These tiny puncture wounds stimulate the body’s healing response and result in the formation of new collagen—just what our skin needs to fill those small holes. And, unlike older lasers, general anaesthetic is not necessary. A quick application of numbing cream is enough to prep the skin. But while the new breed of skin perfecters are gentler, they may require multiple treatments for best results. Slow and steady wins the race, we say.

It’s not your imagination: skin can flair up around work deadlines, crazy-busy days or relationship dramas, says Dr Lim. “The exact cause is unknown but most experts agree [the skin] is linked to the immune system,” he explains. Not only that, when we’re wound up, we can subconsciously pick, stroke or rub our face, causing breakouts in those prone to acne. “When you start fiddling with a patch of skin it becomes sensitive, itchy and it can thicken, just like a callous,” Dr Lim says. Tend to frown when you’re down or purse your mouth when you’re mad? Then know this: “If you constrict your facial muscles regularly, they can become permanent over time,” he says.
