As of 2012 The Food and Drug Administration (FDA) barred the use of “sunblock” as well as claims that sunscreens are “waterproof” or “sweat-proof,” saying those terms are inaccurate.
Sunscreens marked “broad spectrum” protect against both types of damaging UV radiation – UVA and UVB.
Only sunscreens that pass a test that shows they protect the skin from both ultraviolet A (UVA) and ultraviolet B (UVB) rays will be allowed to be labeled “broad spectrum,” and only those that also have a sun-protection factor (SPF) rating of at least 15 can advertise they protect against sunburn, wrinkles and cancer.
To get the widest range of protection, most broad-spectrum sunscreens combine UVB- and UVA-absorbing chemicals and/or physical screens.
SPF value of 30 is critical to ensuring adequate protection in the sun
Although SPF 15 is the FDA's minimum recommendation for protection against skin cancer and sunburn, the AAD recommends choosing a sunscreen with an SPF of at least 30.
You should take additional steps to protect your skin such as:
- Avoiding the sun as much as possible between the hours of 10 a.m. and 4 p.m., seek shade whenever possible,
- Wear protective clothing with long sleeves, pants, wide-brimmed hats and sunglasses.
- Use sunscreens every day if you are going to be in the sun for more than 20 minutes.
- Apply sunscreens to dry skin 15 to 30 minutes before going outdoors.
- When applying sunscreen, pay particular attention to the face, ears, hands and arms, and generously coat the skin that is not covered by clothing.
- One ounce of sunscreen, enough to fill a shot glass, is considered the amount needed to cover the exposed areas of the body completely.
- Reapply sunscreens every two hours or immediately after swimming or strenuous activity.

What SPF sunscreen should you wear?
Sunscreen with a SPFs higher than 50 only provides 2% more protection than an SPF 25-30, which provides 97-98% protection against UVB rays.
All sunscreens need to be applied every 90 minutes, especially if you are outside for more than two hours, actively playing sports, at the beach or gardening.
