Everybody's Free to Wear Sunscreen was an inspirational song by Baz Lurhmann in 1999, and the advice to wear sunscreen is still true 10 years later.

Experts say even on cloudy days, about 80 percent of Ultra violet rays get through.

While we may be free to wear sunscreen, it is not free so we did the research to make sure you get the right product at the right price.

Amy McDonald always makes sure her daughters are covered in sunscreen when they go outside.

"You never know when the sun's going to come out, and especially with our weather this year.  It's so unpredictable.  That's why we try to get as much sunscreen on them as we can," says McDonald.

CancerCare Manitoba's Dr. Dhali Dhaliwal says that is a good habit.

Dhaliwal says UV rays can be high even when the sun is not shining.

He says if you are spending any time outside on a summer afternoon you should cover-up.

Several sunscreens have been tested to determine which ones work the best.

It was not an easy task as there are so many products on the market it is hard to determine which one is best for your needs.

Consumer Reports put 10 sunscreens to the test; most promised to protect against both UVA and UVB rays.

Both UV types can lead to skin cancer.

Sunscreen was rubbed in patches on people's skin at an independent lab.

After waiting at least 15 minutes, the skin was exposed to UVA and UVB radiation.

All of the sunscreens provided good to excellent UVB protection; that is known as the SPF or sun protection factor.

But, after sitting in water nearly all the sunscreens lost a little UVB protection. 

"It should be re-applied every two hours if you're in water where it may wash off," Dhaliwal said.

Consumer Reports tests showed that when it came to protecting against UVA rays, the Banana Boat Kids Tear Free with an SPF of 50 only rated fair.

Another SPF 50 brand, Coppertone's Water Babies rated well.

Even adults can use that sunscreen and benefit from it.

Dhaliwal says you should apply it half an hour before going outside and he says all you really need is a sunscreen with a minimum SPF of 15.

Whether you rub it or spray it on, it is recommended you use a generous amount, and like Baz Lurhmann said, trust us on the sunscreen.

In 2006, 145 Manitobans were diagnosed with melanoma, and 28 Manitobans died from it.
