Ask the Expert: Dr. Cheryl Rosen, TWH Dermatologist and Director of the Canadian Dermatologist Association's National Sun Awareness Program gives tips on summer sun awareness.
Will tanning make me look older?
Prolonged sun exposure is known to cause premature aging of the skin. Skin wrinkling is a common sun induced sign of aging that is measured by examining a person’s face and hands—the two most common places this damage occurs.
Is it actual beneficial to build a base tan before a tropical vacation to avoid a nasty sunburn?
In short, no. Even with an induced tan, prolonged sun exposure puts your skin at the same risk for significant damage and health problems down the road. Any change in skin pigment, whether a tan or burn, is a sign of sun damage that can lead to harmful effects down the road. Both can cause premature aging, DNA damage, and a compromised immune system.
What are some of the lesser known signs of skin damage?
Prolonged sun exposure can also suppress the body’s immune system, making it more susceptible to infection and disease. Many people notice the formation of cold sores, often called sun blisters, after a day outside. They are signs of immuno-suppression; just as a cold wears the body down, so can the sun, with both resulting in pesky cold sores.
What should I look for when choosing sunscreen?
The term "broad-spectrum" will help ensure you are getting the best coverage possible. In addition, it’s important to always pick something that is water-resistant.
How often should I re-apply my sunscreen?
It is important to remember to apply well. If you apply well, you will not need to reapply as often. As a general rule, remember to reapply after swimming and excessive sweating.
How will I get my Vitamin D if I’m not in the sun?
A Vitamin D supplement in pill form is just as effective as the sun. In fact, if you spend too much time in the sun, the active compound that creates Vitamin D gets converted to inactive, therefore stopping the production of Vitamin D.
Should I just stay out of the sun entirely?
Although there are risks to prolonged sun exposure, there is no reason not to go out and enjoy the summer months. We should all be physically active and enjoy the activities we love. Just always remember to protect yourself the best you can for what you are doing.
UV rays are ubiquitous carcinogens. The sun cannot be avoided; but you can protect yourself and your family this summer by wearing sunscreen, covering-up particularly sensitive areas of the body and staying out of direct sunlight during peak hours—11 a.m. to 4 p.m.—on days with high or extreme UV warnings.
