Sun Safety

RECENTLY IN THE NEWS:

NBC News (3/5/2015) reports on its website that "family practioners, gynecologists and even dentists are getting into the cosmetic procedure business, and dermatologists say they're seeing the side effects."  Several dermatologists "from around the country told NBC News that they've had to the fix the mistakes of physicians who are dabbling in their specialty."  In a statement, the American Academy of Dermatology said, "A dermatologist is a licensed medical doctor and the only residency-trained physician fully educated in the science of cutaneous medicine, which includes medical and surgical conditions of the skin, hair, nails, and mucous membranes."

DRY SKIN CARE:

Keep your bathing to a minimum!  Wash with lukewarm water and keep your bathing to less than 10 minutes.  Wash with a soapless cleanser such as Dove and avoid harsh soaps such as Ivory or Irish Spring.  After bathing, moisturize within a few minutes of patting dry with a towel.  Moisturize with a sensitive-skin moisturizer without fragrance.  If you have a skin condition such as eczema, you will need to moisturize a few times per day.

WOUND CARE:

The day after your procedure, allow the cleanser and water to wash over the site.  That is adequate cleaning of the wound.  Thereafter, apply a generous layer of petroleum jelly (Vaseline) or another greasy substance such as Aquaphor healing ointment.  If the area is in contact with clothing, we advise you to cover it with a dressing.  Repeat the same procedure the next day and every day until the wound has healed.

HOW TO APPLY YOUR TOPICAL RETINOID (ACNE PATIENTS):

Topical retinoids include adapalene (Differin), tretinoin (Retin-A, Atralin, Ziana, Veltin, Tretin-X).  Apply a pea-sized amount to your entire face a few minutes after washing your face at bedtime (since most retinoids are inactivated by sunlight).  If your face is dry with the retinoid, apply a moisturizer prior to the application of the retinoid.  

CARE FOR SKIN IN THE SUN:

Use a daily moisturizer with a sunscreen of SPF 15 or higher on the areas that will be exposed.  If you're going to be directly out in the sun, wear an SPF of 30 or higher and make sure the sunscreen says that it is "broad spectrum."  Remember to reapply after two hours and after swimming or any exercising.  Physical sunscreens which contain titanium dioxide and/or zinc oxide are gentle and will not react with the skin.   Seek shade between the hours of 10 am-4 pm.

Check your skin for any new, changing, non-healing or itching lesions four times a year or every major holiday.  If you notice anything that is new or changing or not healing, please call and get it checked.

Because of the ultraviolet radiation it emits, the sun is inherently dangerous to human skin. In fact, the American Academy of Dermatology stipulates that there is no safe way to tan. Tanning is the skin's natural response to damage from the sun. Additionally, the Environmental Protection Agency proclaims that everybody, regardless of race or ethnicity, is subject to the potential adverse effects of overexposure to the sun. That's why everyone needs to protect their skin from the sun every day.

How We Burn

When ultraviolet light penetrates the epidermis it stimulates melanin, the substance responsible for skin pigmentation. Up to a point, the melanin absorbs dangerous UV rays before they do serious damage. Melanin increases in response to sun exposure, which is what causes the skin to tan. This is a sign of skin damage, not health. Sunburns develop when the UV exposure is greater than the skin's natural ability to protect against it.

Sunscreens and Sunblocks

The sun emits two types of ultraviolet (UV) rays that are harmful to human skin. UVA rays penetrate deep into the dermis and lead to wrinkles, age spots and skin cancers. UVB rays are responsible for causing sunburn, cataracts and immune system damage. Melanoma is thought to be associated with severe UVB sunburns that occur before the age of 20.

Sunscreens absorb ultraviolet light so that it doesn't reach the skin. Look for sunscreens with the active ingredients PABA, benzophenones, cinnamates or salicylates. Sunblocks literally block the UV rays instead of absorbing them. Key active ingredients for sunblock success are titanium oxide and zinc oxide.

There is no sunscreen or sunblock that works 100%. The U.S. Food and Drug Administration regulates the manufacture and promotion of sunscreens. Sunscreens are given a SPF (Sun Protection Factor) number that indicates how long a person can remain in the sun without burning. It is recommended that people use products with a SPF of 15 or greater. Sunscreens are not generally recommended for infants six months old or younger. Infants should be kept in the shade as much as possible and should be dressed in protective clothing to prevent any skin exposure and damage.

There is no such thing as "all-day protection" or "waterproof" sunscreen. No matter what the SPF number, sunscreens need to be re-applied every 2 to 3 hours. Products that claim to be "waterproof" can only protect against sunburn up to 80 minutes in the water. Products labeled "water resistant" can only protect against sunburn up to 40 minutes in the water.

Even in the worst weather, 80% of the sun's UV rays can pass through the clouds. Additionally, sand reflects 25% of the sun's UV rays and snow reflects 80% of the sun's UV rays. That's why sunscreen needs to be worn every day and in every type of weather and climate. The sun's intensity is also impacted by altitude (the higher the altitude the greater the sun exposure), time of year (summer months) and location (the closer to the Equator, the greater the sun exposure).

Protecting Yourself From Sun Exposure

  • Look for sunscreens that use the term "broad spectrum" because they protect against both UVA and UVB rays.
  • Choose a sunscreen with a minimum SPF rating of 15.
  • Apply sunscreen 15 to 30 minutes before you head out into the sun to give it time to seep into the skin.
  • Apply sunscreens liberally. Use at least one ounce to cover the entire body.
  • Use a lip balm with SPF 15 or greater to protect the lips from sun damage.
  • Re-apply sunscreen immediately after going into water or sweating.
  • Re-apply sunscreen every 2 to 3 hours.
  • Use sunscreen every day regardless of the weather.
  • Wear sunglasses to protect the eyes from UV rays.
  • Wear wide-brimmed hats and protective clothing to limit skin exposure to the sun.
  • Stay in the shade whenever possible.
  • Avoid using tanning beds.

Treating a Sunburn

If you experience a sunburn, get out of the sun and cover the exposed skin as soon as possible. A sunburn will begin to appear within 4 to 6 hours after getting out of the sun and will fully appear within 12 to 24 hours. Mild burns cause redness and some peeling after a few days. They can be treated with cold compresses on the damaged area, cool baths, moisturizers to prevent dryness and over-the-counter hydrocortisone creams to relieve any pain or itching. It is also important to drink plenty of fluids when you experience any type of sunburn.

More serious burns lead to blisters, which can be painful. It is important not to rupture blisters as this slows down the natural healing process and may lead to infection. You may want to cover blisters with gauze to keep them clean. Stay out of the sun until your skin has fully healed. In the most severe cases, oral steroids may be prescribed to prevent or eliminate infection along with pain-relieving medication.
