Choose a product with an SPF of at least 30.
The Sun Protection Factor (SPF) is a measure of protection against UVB rays from the sun. The higher the sunscreen SPF, the more protection it provides from UVB rays. However, it is worth knowing that for anything above SPF 30, these gains are minimal:
|Warning! A higher SPF does not provide longer protection! Regardless of the SPF, sunscreen must be reapplied every two hours, when outdoors, even on cloudy or cold days, and after swimming or sweating a lot.|
Make sure the sunscreen also protects against UVA radiation.
Filters are active ingredients contained in sunscreens that protect skin against UVA and UVB rays from the sun. There are two types:
To ensure your sunscreen provides adequate protection against both UVA and UVB radiation, look for the words “Broad Spectrum” or the UVA logo on the label.
Opt for a water-resistant product for the swimmers and sports enthusiasts in the family.
The water resistance of the sunscreen is indicated on the packaging: either 40 or 80 minutes. But remember, any time you wipe your skin with a towel, you remove part of the product and reduce its efficacy. So, it is important to reapply the product even if you haven’t yet reached the water resistance limit.
Consider how easy the product is to apply.
Sunscreens come in various forms: creams, lotions, sprays, sticks, and others, each with its pros and cons. For example:
No matter which form you prefer, don't forget your lips! To protect your lips, use a lip balm with an SPF of at least 30 and reapply every hour when you are outdoors.
Protect your sunscreen from extreme temperature, and never use expired products.
To prevent sunscreens from deteriorating too fast, always store them away from sources of heat. Do not leave them in the car.
Do not use the product once it has passed the expiration date.
No matter which product you use, apply it regularly and generously.
Even the very best sunscreen will not protect you properly if you don’t apply enough of it. It takes about 7 teaspoons (35 mL) of cream or lotion to cover an adult’s entire body:
Remember to apply sunscreen on these often-forgotten areas: your hands, the tip of your nose and ears, the back of your neck, and the top of your feet.
Sunscreen should be reapplied every two hours, because its protective effect diminishes over time in the sun. Always reapply after swimming or partaking in an activity where you sweat a lot.
