Myths About Sunscreen

Tired of hearing about sunscreen? We all know it is important and helps prevent skin cancer and should be worn daily (which most of us don't), yadda yadda yadda... But what don't we know?? Whether you live in Hawaii where the sun is out year round or are enjoying a cold, cloudy winter, let's explore some important facts about sunscreen...

1. Applying sunscreen once in the morning is enough

False: If you are going to be out in the sun all day, sunscreen should be applied every 2 hours, and if you are sweating or swimming, every 40 minutes.

2. Children are exposed to the sun more than adults

True: Up to 80% of lifetime sun exposure likely occurs before the age of 18. Teach children from a young age to protect their skin properly and they'll establish healthy patterns for the rest of their life.

3. There is a huge difference in SPF ratings

False: It's a common misconception that SPF 100 is twice as effective as SPF 50. In reality, SPF 50 blocks 98% of UV rays compared to the 99% of SPF 100. And the old standby, SPF 30, blocks 96.7% of harmful UV rays.

4. A thin layer of sunscreen works just as well as more

False: The recommended amount is more than most realize – one ounce or a full palm-full (the equivalent of a shot glass).

5. You should replace sunscreen frequently

True: Like most products, sunscreen loses effectiveness and can stop working altogether. Effectiveness decreases after a year, so before relying on that bottle from last summer to protect you at the beach, go ahead and replace it.

6. Even on a cloudy day, you should wear sunscreen

True: Up to 80% of UV rays can pass through clouds. Keep in mind that sand reflects 25% of the sun's rays and snow, 80%.

7. Using sunscreen is enough to prevent skin cancer

FALSE. Sunscreen is important in skin cancer prevention; however, it is not a complete solution. One of the most important preventive methods is avoiding sun exposure during the middle of the day when the sun's rays are at their strongest. If you are heading to the beach, take an umbrella and a long sleeved cover-up. And don't forget to protect your eyes with a quality pair of sunglasses.
