Now that the weather is finally warming up, it’s time to start remembering to use sunscreen. Don’t think you’re protected just because you put some on at the beginning of the day. Dermatologists say the biggest mistake people make is not using enough. Re-apply it periodically throughout the day, frequently if you’re exercising in the heat. A 120-millilitre tube is only good for about four or five applications. Use a broad-based sunscreen with both UVA and UVB protection with a minimum (SPF) of 30. Reduce your exposure to the sun, between 11 a.m. and 4 p.m. Wear clothing that protects as much skin as possible. Wear a wide-brimmed hat and wraparound sunglasses with UVA and UVB protection. You may be asking yourself how this advice squares with everything you’ve heard about the benefits of Vitamin D – which you get from exposure to the sun. The Canadian Dermatology Association says most Canadians get enough vitamin D in the spring, summer and fall from their exposure to the sun in their normal daily routines, and there’s no need to revisit the recommendations on sunscreen.
