Skin Care Tips Sun Damage Sunscreen UVA/UVB

 The Skin Cancer Foundation strongly recommends we protect our skin with sunscreen everyday.   Skin damage from unprotected ultraviolet exposure becomes cumulative. 

“Daily use of a sunscreen can reduce the cumulative effect of UV damage.  Cancer-Preventive Effects of Sunscreen. 

As of 2012 The Food and Drug Administration (FDA) barred the use of “sunblock” as well as claims that sunscreens are “waterproof” or “sweat-proof,” saying those terms are inaccurate.UVA & UVB Rays

Sunscreens marked “broad spectrum” protect against both types of damaging UV radiation – UVA and UVB.

Only sunscreens that pass a test that shows they protect the skin from both ultraviolet A (UVA) and ultraviolet B (UVB) rays will be allowed to be labeled “broad spectrum,” and only those that also have a sun-protection factor (SPF) rating of at least 15 can advertise they protect against sunburn, wrinkles and cancer.

To get the widest range of protection, most broad-spectrum sunscreens combine UVB- and UVA-absorbing chemicals and/or physical screens.

SPF value of 30 is critical to ensuring adequate protection in the sun

Although SPF 15 is the FDA's minimum recommendation for protection against skin cancer and sunburn, the AAD recommends choosing a sunscreen with an SPF of at least 30.

You should take additional steps to protect your skin such as:

  • Avoiding the sun as much as possible between the hours of 10 a.m. and 4 p.m., seek shade whenever possible,
  • Wear protective clothing with long sleeves, pants, wide-brimmed hats and sunglasses.  
  • Use sunscreens every day if you are going to be in the sun for more than 20 minutes.
  • Apply sunscreens to dry skin 15 to 30 minutes before going outdoors.
  • When applying sunscreen, pay particular attention to the face, ears, hands and arms, and generously coat the skin that is not covered by clothing.
  • One ounce of sunscreen, enough to fill a shot glass, is considered the amount needed to cover the exposed areas of the body completely.
  • Reapply sunscreens every two hours or immediately after swimming or strenuous activity.

All sunscreens need to be applied every 90 minutes, especially if you are outside for more than two hours, actively playing sports, at the beach or gardening.

More Sunscreen Tips

Everyone should be wearing sun protection everyday.  Here are a few more sunscreen tips to encourage you to do so.

  • Although SPF 15 is the FDA's minimum recommendation for protection against skin cancer and sunburn, the AAD recommends choosing a sunscreen with an SPF of at least 30.
  • UVA rays (aging rays) can prematurely age your skin, causing wrinkles and age spots, and can pass through window glass.
  • sunscreens labeled “broad spectrum must pass a test that shows they protect the skin from both ultraviolet A (UVA) and ultraviolet B (UVB) rays
  • UVB rays (burning rays) are the primary cause of sunburn and are blocked by window glass.

Study shows poor skin cancer survival in patients with skin of colorEveryone Needs To Wear Sunscreen

Dermatologist urges everyone to be aware of their risk and take steps toward prevention, detection —SCHAUMBURG, Ill. (July 28, 2016) — Because Caucasians have a higher skin cancer risk than the general population, people with skin of color may believe that they don’t need to be concerned about this disease — but new research reveals this to be a dangerous misconception. 

According to a study published online in the Journal of the American Academy of Dermatology on July 28, although melanoma incidence is higher in Caucasians, patients with skin of color are less likely to survive the disease.
Sunscreen for African American Skin
“Everyone is at risk for skin cancer, regardless of race,” says board-certified dermatologist Jeremy S. Bordeaux, MD, MPH, FAAD, one of the study authors. “Patients with skin of color may believe they aren’t at risk, but that is not the case — and when they do get skin cancer, it may be especially deadly.”   

 

 

 

Phototoxic Reaction

  • More common
  • Change in the skin is usually observed within minutes to hours following exposure to the offending substance photoallergic reaction

Photoallergic Reaction

Response is not observed for 1 - 3 days after the substance has come into contact with the body

 

 Photosensitivity is an increased sensitivity or abnormal response of the skin to sunlight or artificial light. In particular, exposure to both UVA  and UVB rays have been seen to trigger unusual reactions of the skin in people with certain disorders or those who are taking particular medications or substances.  Redness (erythema) of the skin, similar to sunburn or rash or the sun-exposed area. 

A phototoxic reaction from medication usually clears up when the drug is no longer used or in the body, even after re-exposure to the original light source.

It’s the combination of the photosensitizing medications or chemical substance plus the light source that causes the photosensitivity reaction. 

In photoallergic reactions, the body’s immune system sees the antigen as an enemy combatant.  The  immune system then kicks off an allergic response causing inflammation of the skin in the sun-exposed area.  This type of photosensitivity may recur after sun exposure even after the drug has been cleared from the system and can sometimes spread to areas of the skin unexposed to the sun.
