Prevention magazine identifies myths and facts about skin care, treatments
With such an abundance of health-related information and oft-repeated advice out there, which tidbits are mere myths and which are actual facts? Here, Prevention magazine provides clarity about common questions related to skin and skin care.
Myth or fact? The way your skin ages is largely determined by your genetics.
MYTH. A recent study that analyzed identical twins found that your lifestyle significantly trumps your DNA when it comes to facial aging. Experts estimate that daily habits account for up to 80 percent of the changes in appearance that occur over time. The good news is that with a few precautions, like wearing an SPF 30 sunscreen every day, you can look vibrant and youthful no matter how many candles are on your birthday cake.

Myth or fact? High stress levels can cause your skin to age more quickly.
FACT. Emotional upheavals can make your skin look five years older than your chronological age. Constant anxiety increases the stress hormone cortisol, which causes inflammation that breaks down collagen. It also triggers a chain of responses that can lead to facial redness and acne flare-ups. Try to exercise and meditate a little every day, which have been shown to lower stress-hormone levels. To quell inflammation, eat antioxidant-rich foods such as berries, oranges and asparagus.

Myth or fact? All babies are born without freckles.
FACT. Babies, of course, can be born with birthmarks and "beauty marks," but it's true that upon entering the world they have no freckles, which the skin produces (using excess pigment) in response to sun exposure. As babies get out in the sun, those with fair complexions and light eyes will be especially prone to developing freckles (and will have a higher likelihood of skin cancer and melanoma later in life). Those freckles on the redheaded kid's cheeks aren't cute — they're sun damage! And freckles probably also indicate damage to the DNA in your skin cells. Children and adults alike should have their freckles monitored regularly by a dermatologist and vigilantly use sunscreen of SPF 30 or higher.

Myth or fact? The most important time to wash your face is when you first wake up in the morning.
MYTH. The most important time to wash your face is before you head to bed. Dirt, bacteria and makeup left on overnight can irritate skin, clog pores and trigger breakouts. Remove this top layer of grime with a gentle face wash (skin should feel pleasantly tight for 10 to 15 minutes post-cleansing), which also allows anti-agers to penetrate deeper for better results. Because oil production dips with hormonal changes in your 40s, cleansing twice daily can dry out your complexion and make wrinkles look more pronounced. To refresh skin in the morning, splash with lukewarm water.

Myth or fact? Drink more water if you have dry skin.
MYTH. Unless you're severely dehydrated, the amount of water you consume has no effect on how dry your skin is. Overhydrating may even take a toll on skin by flushing electrolytes out of your bloodstream. Aim to meet the Institute of Medicine of the National Academies recommendation to consume 91 ounces of fluid a day (around 11 cups). Remember, choosing food (like fruits and veggies) with a high water content helps you meet your quota.

Myth or fact? Your ears are still growing.
FACT. Your outer ears are. Starting at birth, the ears are, proportionally, the body's largest feature, with a Spock-like prominence. They grow rapidly until about age 10, then slow to the languid pace of about 0.22 millimeter per year, according to a study by Britain's Royal College of General Practitioners. Other studies show that the earlobe itself also lengthens throughout life (men have longer lobes than women). However, the size of the ear canal, which is formed by bone and cartilage, does not increase into old age.

Myth or fact? Eating tomatoes can help prevent sunburn.
FACT. This is true, thanks to tomatoes' high lycopene content. Volunteers in one study who consumed 5 tablespoons of tomato paste daily for three months had 25 percent more protection against sunburn. Even better, skin had more collagen, which prevents sagging. German scientists also report that higher skin levels of this antioxidant correlate to fewer fine lines and furrows. Toss some on top of some romaine lettuce for the perfect skin-health salad: six leaves of romaine lettuce provide more than 100 percent of your daily value of vitamin A, which revitalizes skin by increasing cell turnover.

Myth or fact? When it comes to beauty products, expensive brands work better than mass-market products.
MYTH. Mass lines make more money, so they can afford more research and development. Among the best: Unilever (which does Dove and Ponds), L'Oréal (Vichy and La Roche-Posay), and Johnson & Johnson (maker of Neutrogena and Aveeno, which has its own research institute). A recent study found that 80 percent of women who followed a skin care regimen with mass-market products showed fewer wrinkles and healthier skin than when they used pricier lines.
