Learn How to Apply Sunblock

I have a bad habit of not reading directions. Most of the time it isn't a big deal, but when it comes to protecting yourself against the sun, reading directions is necessary. This weekend, we celebrated Memorial Day like many other families with a day at the beach. For the first time in my life, I actually read the directions on how to apply sunscreen lotion. I was surprised to learn I have been doing it wrong my whole life. What makes it worse, recent studies from the University of North Carolina have told us that applying sunscreen incorrectly can be more harmful than not using any sunscreen at all.

Here are some interesting insights into the world of sunscreen:

  • SPF (sun protection factor) indicates the time a person can be exposed to sunlight before getting sunburn with a sunscreen applied (compared to the time they can be exposed without sunscreen). For example, if you burn after 12 minutes in the sun, you would expect to burn after 4 hours if protected by a sunscreen with SPF 20.
  • Conventional sunscreen does not block UVA as effectively as it does UVB, and an SPF rating of 30+ may translate to significantly lower levels of UVA protection according to a 2003 study. The best UVA protection is provided by products that contain zinc oxide or mexoryl.
  • You can still get sunburned no matter what your ethnic background, whether or not you have a "base" tan and even on a cloudy (or in the shade).

Read the directions on your particular sunscreen lotion, but here are some recommendations:

  • Apply sunscreen at least 30 minutes prior to exposure, about one ounce should cover an average human being.
  • Make sure your skin is clean and dry (no sweat) before applying.
  • Re-apply sunscreen 30 minutes after being in the sun regardless of physical activity or circumstance.
  • Re-apply every two hours after that (more often if you are swimming or sweating).
  • Sunscreen should be applied anyday you are going to be exposed for more than 20 minutes.
  • Apply sunscreen underneath make-up. Don't forget about lip balm with SPF of at least 15.
  • Sunscreen should last 3 years under ideal conditions.

In case you forget to cover up and apply sunscreen, the resulting sunburn can be painful as well as dangerous. It may take up to 24 hours before the full damage of overexposure is visible.
The two most common sunburns are first-degree burns and second degree burns.
First-degree sunburns cause redness and will heal, possibly with some peeling, within a few days. These can be painful and are best treated with cool baths, aloes, moisturizers and hydrocortisone creams. Avoid the use of “-caine” products (such as benzocaine), which may cause sensitivity to a broad range of important chemicals. Aspirin taken orally may lessen early development of sunburn.
Second degree sunburns blister and can be considered a medical emergency if a large area is affected. When a burn is severe, accompanied by a headache, chills or a fever, seek medical help right away. Be sure to protect your skin from the sun while it heals and thereafter. Most studies have found an association between sunburn and enhanced risk for melanoma, particularly if you suffered severe childhood or adolescent sunburn since there is more time for melanoma to develop over your lifetime.
