Skin Care

1. Protect yourself from the sun

One of the most important ways to take care of your skin is to protect it from the sun. A lifetime of sun exposure can cause wrinkles, age spots and other skin problems — as well as increase the risk of skin cancer.

For the most complete sun protection:

• Use sunscreen. Use a broad-spectrum sunscreen with an SPF of at least 15. When you're outdoors, reapply sunscreen every two hours — or more often if you're swimming or perspiring.
• Seek shade. Avoid the sun between 10 a.m. and 4 p.m., when the sun's rays are strongest.
• Wear protective clothing. Cover your skin with tightly woven long-sleeved shirts, long pants and wide-brimmed hats. Also consider laundry additives, which give clothing an additional layer of ultraviolet protection for a certain number of washings, or special sun-protective clothing — which is specifically designed to block ultraviolet rays.

2. Don't smoke

Smoking makes your skin look older and contributes to wrinkles. Smoking narrows the tiny blood vessels in the outermost layers of skin, which decreases blood flow. This depletes the skin of oxygen and nutrients that are important to skin health. Smoking also damages collagen and elastin — the fibers that give your skin its strength and elasticity. In addition, the repetitive facial expressions you make when smoking — such as pursing your lips when inhaling and squinting your eyes to keep out smoke — can contribute to wrinkles.

If you smoke, the best way to protect your skin is to quit. Ask your doctor for tips or treatments to help you stop smoking.

3. Treat your skin gently

Daily cleansing and shaving can take a toll on your skin. To keep it gentle:

• Limit bath time. Hot water and long showers or baths remove oils from your skin. Limit your bath or shower time, and use warm — rather than hot — water.
• Avoid strong soaps. Strong soaps and detergents can strip oil from your skin. Instead, choose mild cleansers.
• Shave carefully. To protect and lubricate your skin, apply shaving cream, lotion or gel before shaving. For the closest shave, use a clean, sharp razor. Shave in the direction the hair grows, not against it.
• Pat dry. After washing or bathing, gently pat or blot your skin dry with a towel so that some moisture remains on your skin.
• Moisturize dry skin. If your skin is dry, use a moisturizer that fits your skin type. For daily use, consider a moisturizer that contains SPF.

4. Eat a healthy diet

A healthy diet can help you look and feel your best. Eat plenty of fruits, vegetables, whole grains and lean proteins. The association between diet and acne isn't clear — but some research suggests that a diet rich in vitamin C and low in unhealthy fats and processed or refined carbohydrates might promote younger looking skin.

5. Manage stress

Uncontrolled stress can make your skin more sensitive and trigger acne breakouts and other skin problems. To encourage healthy skin — and a healthy state of mind — take steps to manage your stress. Set reasonable limits, scale back your to-do list and make time to do the things you enjoy. The results might be more dramatic than you expect.

Acne

A pimple starts when the pores in the skin become clogged with a type of oil called sebum, which normally lubricates the skin and hair. Acne is common duringpuberty when hormones go into overdrive, causing the skin to overproduce sebum. Because many oil-producing glands are on the forehead, nose, and chin, this area — the T-zone — is where a person is most prone to pimples.

Here are some tips to help prevent breakouts and clear them up as fast as possible:

• Wash your face twice a day (no more) with warm water and a mild soap made for people with acne. Gently massage your face with circular motions. Don't scrub. Overwashing and scrubbing can cause skin to become irritated. After cleansing, the American Academy of Dermatology (AAD) recommends applying an over-the-counter (no prescription needed) lotion containing benzoyl peroxide. This will decrease oil and bacteria.
• Don't pop pimples. It's tempting, but here's why you shouldn't: Popping pimples can push infected material further into the skin, leading to more swelling and redness, and even scarring. If you notice a pimple coming before a big event, like the prom, a dermatologist can often treat it for you with less risk of scarring or infection.
• Avoid touching your face with your fingers or leaning your face on objects that collect sebum and skin residue like your phone. Touching your face can spread the bacteria that cause pores to become inflamed and irritated. To keep bacteria at bay, wash your hands before applying anything to your face, such as treatment creams or makeup.
• If you wear glasses or sunglasses, make sure you clean them frequently to keep oil from clogging the pores around your eyes and nose.
• If you get acne on your body, try not to wear tight clothes. They don't allow skin to breathe and may cause irritation. Scarves, headbands, and caps can collect dirt and oil, too.
• Remove your makeup before you go to sleep. When buying makeup, make sure you choose brands that say "noncomedogenic" or "nonacnegenic" on the label. Throw away old makeup that smells or looks different from when you first bought it.
• Keep hair clean and out of your face to prevent additional dirt and oil from clogging your pores.
• Protect your skin from the sun. It may seem like a tan masks acne, but it's only temporary. A tan may worsen your acne, not improve it. Tanning also causes damage to skin that will eventually lead to wrinkles and increase your risk of skin cancer.

Sun and Skin

We all know we need to protect our skin from the sun's harmful rays. Of course, it's impossible to avoid the sun — who wants to hide indoors when it feels so great to get outside? And the sun's not all bad, anyway: Sunlight helps our bodies create vitamin D. So follow these tips when you're outdoors to help manage sun exposure:

• Wear sunscreen with a sun protection factor (SPF) of at least 15, even if it's cloudy or you don't plan on spending a lot of time outdoors. If you sweat a lot or go swimming, reapply sunscreen every 1½ to 2 hours (even if the bottle says the sunscreen is waterproof).
• Choose a sunscreen that blocks both UVA and UVB rays. Look for the words "broad spectrum protection" or UVA protection in addition to the SPF of 15 or greater. Select a sunscreen that says "nonacnegenic" or "noncomedogenic" on the label to help keep pores clear.
• The sun's rays are strongest between 10:00 AM and 4:00 PM, so reapply sunscreen frequently and take breaks indoors if you can. If your shadow is longer than you are tall, then it's a safer time to be in the sun (you should still wear sunscreen, though).
• Apply more sunscreen (with higher SPF) when you're around reflective surfaces like water, snow, or ice.
• We all know that the sun can damage skin, but did you know it can contribute to eye problems, too? Protect your face and eyes with a hat and sunglasses that provide 100% UV protection.
• Some medications, such as prescription acne medications, can increase your sensitivity to the sun (and to tanning beds). So if you're taking medication, increase your sun protection.
• If you want the glow of a tan, try faking it with self-tanners. Avoid tanning beds. They still contain some of the same harmful UV rays as the sun.

Cold Sores

Cold sores usually show up as tender blisters on the lips. They are caused by a type of herpes virus (HSV-1, which most often is not sexually transmitted) so they are contagious from person to person. Once you get this virus it stays in your body, meaning you'll probably get cold sores every now and then throughout your life.

Here are ways you can help prevent cold sores from making an appearance (or reappearance if you've had them in the past):

• Avoid getting cold sores in the first place by not sharing stuff like lip balm, toothbrushes, or drinks with other people who might have cold sores. The virus that causes cold sores is transmitted through the nose (in mucus) and the mouth (in saliva).
• People who have the virus know that cold sores can flare up from things like too much sun, stress, or being sick. Just one more reason to lather on that suntan lotion, eat well, exercise, and get plenty of sleep!

If you do have a cold sore, here are some tips for keeping yourself comfortable:

• Take acetaminophen or ibuprofen if the cold sores are painful.
• Suck on ice pops or cubes to ease pain and keep cold sores cool.
• Stay away from acidic foods (like oranges, tomatoes, and lemonade) and salty, spicy foods, which can cause irritation.
• Don't pick at cold sores while you're waiting for them to go away. They may bleed or become infected with bacteria or you could spread the virus.

Eczema

Eczema is a condition that causes skin to become red, itchy, and dry. If you have eczema, you might notice that you are prone to getting itchy rashes — especially in places like where your elbows and knees bend or on your neck and face. The symptoms of eczema can vary from person to person.

Though you can't cure eczema forever, you can take steps to prevent it from flaring:

• Stay away from things like harsh detergents, perfumed soaps, and heavily fragranced lotions that tend to irritate the skin and trigger eczema.
• Because hot water dries by quick evaporation and over-washing with soap may dry skin, take short, warm showers and baths. If you're going to have your hands in water for a long time (like when you're washing dishes or your car), try wearing gloves. Detergent can dry and irritate skin.
• Soothe your skin with regular applications of a fragrance-free moisturizer to prevent itching and dryness. Creams generally moisturize a bit better and last longer than lotions for most people. Creams work best if applied when the skin is slightly wet, like just after bathing.
• Be careful which fabrics you wear. Cotton is good because it's breathable and soft. (But if you are exercising, some of the newer synthetic materials actually keep you drier and are better for you than cotton.) Try to stay away from materials like wool or spandex that may cause irritation or allergic reactions.
• Keep stress in check. Because stress can lead to eczema flares, try activities like yoga or walking after a long day to keep your stress levels low.
• If you wear makeup, look for brands that are free of dyes and fragrances that can aggravate eczema.
