With sunnier weather approaching, dermatologists now recommend a broad-spectrum sunscreen that protects against both UVB and UVA rays.
For years, consumers have relied on SPF, sun protector factor, to protect their skin against harmful UVB rays -- short, ultraviolet rays that cause sunburn and most skin cancers.
But today, we know longer, UVA rays also play a role in skin cancer. So how do you know which sunscreen brand to purchase?
For starters, look for those that only have the seal of the Canadian Dermatology Association. Also, more expensive brands often mean fewer ingredients -- and that's better for people with sensitive skin.
Good sunscreens block both UVA and UVB rays, are less likely to cause skin irritation and are at least water resistant.
To protect against the harmful UVA rays that cause aging, wrinkles and skin cancer, look for products that contain a combination of micronized titanium dioxide, Parsol 1789 or Mexoryl XL.
To block out the UVB burning rays, check the SPF number.
"I prefer to use higher (SPF) numbers on kids," said Dermatologist Dr. Paul Cohen. For kids, look for those with an SPF of 30 or more.
Sunscreen should be applied 15 to 30 minutes before heading outside, then reapplied every two hours or immediately after swimming, even if the product is waterproof.
But sunscreen is only a start: Wearing a wide-brimmed hat and sun protective clothing is another way to protect yourself.
The degree of protection depends on the weave and chemical additives in the fabric -- and darker colours block more UV rays. For the best protection, the tag on the fabric should be listed with a UPF 50 rating.
And don't forget the glasses, even for babies.
B.C. Children's Hospital recommends a Kids Sun Dome and Stroller Cover, made with sun protective fabric, which they sell at their Safety Station at the hospital.
