Who should use sunscreen?
Everyone except infants younger than six months should use sunscreen, according to the American Academy of Dermatology.
What should you look for in sunscreen?
The American Academy of Dermatology recommends sunscreen that has:
- Broad-spectrum protection, which shields UVA and UVB rays.
- UVA rays cause lasting skin damage, contribute to skin aging.
- UVB rays cause sunburns and skin damage.
- Sun protection factor (SPF) of 30 or higher. Higher SPF equals more protection, but no sunscreen blocks 100% of UV rays.
- Water-resistance to withstand water sports and sweating.
- Water resistant: effective up to 40 minutes in water.
- Very water resistant: effective up to 80 minutes in water.
- No sunscreen is completely waterproof.
Avoid combination products, such as moisturizer with SPF or sunscreen with insect repellent, as sunscreen needs to constantly be reapplied, while other products do not.
Toss your sunscreen if:
- It's more than three years old,
- The expiration date has passed,
- The color or consistency has changed or
- The container has been exposed to high temperatures.
When should you wear sunscreen?
Any time you're exposed to the sun, wear sunscreen. Sun protection isn’t just for summer, either:
- Snow, sand and water reflect harmful UV rays.
- 80% of UV rays reach your skin on cloudy days.
When should sunscreen be applied?
- Put it on 15 to 20 minutes before sun exposure and
- Two hours after every application, swimming or sweating.
Where to apply sunscreen is easy to remember — on all skin that is not covered by clothing. Don't forget about:
- tops of feet and
- backs of hands.
Use at least one ounce, about the size of a quarter, to cover exposed areas.
Different types of sunscreen work better on different areas:
- Face - cream sunscreen,
- Scalp - gel sunscreen,
- Around your eyes - stick sunscreen and
- Body - lotion or spray sunscreen.
