5 TIPS FOR CHOOSING THE RIGHT SUNSCREEN

SUN PROTECTION FACTOR

Opt for a sunscreen with an SPF of at least 30. SPF, or Sun Protection Factor, measures protection against UVB rays. While higher SPF values offer more UVB protection, it’s essential to note that the benefits taper off beyond SPF 30:

• SPF 30 blocks 96.7% of UVB rays
• SPF 50 blocks 98% of UVB rays
• SPF 60 blocks 98.3% of UVB rays

Remember, a higher SPF doesn’t mean longer protection. Regardless of the SPF level, reapply sunscreen every two hours while outdoors, even on cloudy or cold days, and especially after swimming or heavy sweating.

PROTECTION AGAINST UVA AND UVB

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: 

• Synthetic (or chemical) filters transform UVA or UVB rays, rendering them harmless. Often, more than one chemical filter is required in a single product to obtain proper protection against all UVA and UVB rays. 
• Mineral filters (zinc oxide or titanium dioxide) form a reflective barrier on the skin’s surface. They offer protection against UVA and UVB rays alike. 

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.

WATER RESISTANCE

Choose a water-resistant sunscreen for family members who enjoy swimming and sports.

The sunscreen’s water resistance is clearly labeled, usually for either 40 or 80 minutes. It’s crucial to keep in mind that every time you wipe your skin with a towel, you may remove some of the sunscreen, diminishing its effectiveness. Therefore, even if you haven’t reached the water resistance limit, it’s essential to reapply the sunscreen.

EASE OF APPLICATION

Take into account the ease of application when selecting a sunscreen.

Sunscreens are available in various forms, including creams, lotions, sprays, sticks, and more, each with its advantages and drawbacks. For instance:

• Creams and lotions are great for larger areas and are less greasy than some creams, making them suitable for facial use.
• Sprays are convenient for covering hard-to-reach spots, but be mindful of wind when applying them. Never spray sunscreen directly onto the face; instead, spray it onto your hands and then apply it to your face.
• Sticks are useful for applying sunscreen to the face and reduce the risk of getting the product in your eyes. When using a stick on larger skin areas, be sure to rub it in thoroughly with your hands to avoid leaving any areas unprotected.
• Gels can be a good choice for hairy skin, such as the chest, legs, or scalp.

Regardless of your preferred form, don’t forget to protect your lips! Use a lip balm with an SPF of at least 30 and reapply it every hour when you’re outdoors.

PRODUCT PRESERVATION

To preserve the effectiveness of your sunscreen, keep it away from extreme temperatures, especially the heat. Don’t leave it in a hot car.

Never use sunscreen that has expired; its protection may no longer be reliable.

Regardless of which sunscreen you choose, make sure to apply it regularly and generously. Even the best sunscreen won’t provide adequate protection if you use too little. You’ll need approximately 7 teaspoons (35 mL) of cream or lotion to cover your entire body, including:

• 1 teaspoon for each arm and leg
• 1 teaspoon for the front and back of your torso
• 1 teaspoon for your face

Don’t forget to apply sunscreen to commonly overlooked areas, such as your hands, the tips of your nose and ears, the back of your neck, and the tops of your feet.

Remember to reapply sunscreen every two hours, as its effectiveness diminishes with time in the sun. Be sure to reapply after swimming or engaging in activities that make you sweat a lot.
