What does broad-spectrum mean?
Sunscreens that protect against both UVA and UVB rays are considered “broad spectrum” sunscreens, which are recommended for everyone.

When & how often do I need to reapply?
About one ounce (5-6 teaspoons) should be applied to entire body about every 2 hours during prolonged exposure, swimming or heavy perspiration. Sunscreen should be applied 30 minutes before going outdoors.  It takes time for it to start working.  Water-resistant sunscreens are recommended when you are working outside or will be out swimming or perspiring.

What does SPF mean?
SPF is an abbreviation for sun protection factor, a number that tells us how long the sunscreen is effective on the skin.  Even if the SPF number is greater than 30 all sun screens should be applied every 2 hours during prolonged exposure, swimming or perspiration.

Do sunscreens expire?
Yes, they are designed to remain stable for about 2 to 3 years.  Check the expiration date on the container for the date it becomes ineffective.

What is a physical sunscreen?
Physical sunscreens contain extremely fine particles of minerals such as zinc oxide and titanium dioxide that stay on the skin’s surface, creating a barrier that reflects the sun’s rays.  Physical sunscreens are water resistant; reflect skin-damaging heat while keeping the skin cool.  They are considered to be natural sun protectants since zinc oxide and titanium dioxide are minerals.  They create a barrier on the skin so they are unlikely to cause skin irritation.  They tend to be heavier than chemical sunscreens and may leave a white residue on the skin.  Main ingredients to look for:  Titanium Dioxide, Zinc Oxide and Iron Oxide.

What is a chemical sunscreen?
Chemical sunscreens contain synthetic compounds as the active ingredients and absorb the ultraviolet radiation that causes sunburns, damages DNA and can lead to skin cancer.  They absorb UVA rays which penetrate into the deeper layers of the skin, damaging collagen fibers and other tissues.  Chemical sunscreens also prevent penetration of UVB rays responsible for tanning and sunburns.  They can cause allergic reactions and may irritate sensitive skin.  Chemical sunscreens are broken down quickly so you need to reapply often.  Main ingredients to look for:  Parsol, Benzophenones, Octyl Methoxycinnamate, and Mexoryl XL.
