“Broad-spectrum” is the term you’ll most often see in the United States because it’s regulated by the Food and Drug Administration (FDA).

UVA rays, which can get through glass, are more insidious because they affect your skin beneath the surface, even when you can’t feel it burning.įor that reason, you’ll want to make sure your sunscreen says “ broad-spectrum,” “UVA/UVB protection,” or “multi-spectrum” on the label. UVB rays are shorter and can’t penetrate glass, but they’re the ones that cause sunburn. The sun emits different types of light rays, two of which are primarily responsible for damaging your skin: ultraviolet A (UVA) and ultraviolet B (UVB).
It’s important to remember that while higher SPFs offer more protection, they don’t last any longer than lower numbers, so you need to reapply them just as often. A sunscreen with an SPF of 30, when used as directed, prevents 97% of UVB rays from reaching your skin. Sun protection factor (SPF) measures how much solar energy is required to cause a sunburn when you’re wearing sunscreen compared with unprotected skin. Plus, the stick makes for easy reapplying on the go. Thinkbaby SPF 30 Stick covers the basics without the glue-like feeling. To recap: “SPF 30 is the minimum I recommend, but higher is always better,” says Frey. But that extra protection is worth it for a beach day, even if you don’t want to opt for it daily. At a minimum, you’ll want SPF 30.įrey adds that higher SPFs tend to be stickier, so some people don’t like them as much. Recent research shows that SPF 100, when compared with SPF 50, makes a real difference in protecting your skin against damage and burns.
New York dermatologist Fayne Frey reminds us that “no sunscreen is 100% effective at preventing burning and skin damage.” She also notes that sunscreen “can increase the amount of time you can be outside.”Īnd the amount of time spent outside is somewhat correlated to SPF.
