Product Information

SPF 100 sunscreen keeps out nearly 99% of UVB radiation. When you use a long-lasting sunscreen with SPF 100, it would take you 100 times longer to experience sunburn as compared to no sunscreen. A higher range of SPF prevents more damaging UVB rays from penetrating than a lower range of SPF. So, an SPF 100 sunscreen translates into higher sun protection and lesser skin damage. SPF—or sun factor protection—measures how well the sunscreen protects your skin against the sun's harmful UVB radiation, says Dr. Michele Green, a cosmetic dermatologist in NYC. Today, shelves are lined with everything from 4 on the very low end to 100+ on the very high end. But, a higher number on that bottle doesn't necessarily mean it's "better" for you. Here, dermatologists break down whether or not you should be reaching for SPF 100. So... is SPF 100, or high SPF in general, really more effective? Largely, yes, but the clearer consensus among dermatologists is that a sunscreen that boasts both UVA and UVB protection is always the best way to go. And experts confirm that all of this is null and void if we don't apply sunscreen correctly in the first place.

Now that you have been through our review of the 6 best SPF 100 sunscreens, let us help you with a few tips to keep in mind while choosing your sunscreen, so that you derive the maximum benefit and keep your skin safe from sunburn and harmful radiations. There are many great sunscreens available, here’s how to choose one that fits your needs. How To Choose A Sunscreen With SPF 100 You should also wear protective clothing, such as wide-brimmed hats, beach cover-ups, longer sleeves when possible, and sunglasses when possible, says Dr. Engleman.

HOW TO USE

On the flip side, SPF 100 tends to make people feel rather invincible in the sun—which can lead to misuse. So, what’s the deal? Here's everything you need to know about SPF 100, who should use it, and how to apply it the right way. Whatever product you choose, experts recommend using a water-resistant sunscreen applied liberally one half hour before going outdoors. Sunscreen should be reapplied at least every two hours or after swimming, drying off, or sweating. A physical sunscreen, mineral sunscreen, or inorganic sunscreen may have either zinc oxide or titanium dioxide as an active ingredient. These Zinc oxide sunscreens or Titanium dioxide sunscreens create a protective barrier on your skin that reflects and scatters UV rays, but new research shows that inorganic sunscreens may actually protect your skin by absorbing up to 95% of the rays. I have been using the SPF 30 formula for a few years and love it because it adds a subtle dewy radiance on my face that works well under makeup, spreads easily, and does not have a white cast.

I love the Neutrogena Ultra Sheer Dry-Touch line. It prevents sunburn while still allowing my skin to get some color, it has a non-greasy feel, and it has just a very faint floral scent that is not obnoxiously "beachy." The findings are detailed in Valisure's May 24 petition to the Food and Drug Administration to recall the product lots that contain dangerous amounts of benzene. Benzene, an industrial chemical normally found in crude oil and cigarette smoke that can also be used in manufacturing plastic and pesticides, is a known human carcinogen that can cause harm with long-term exposure, which is exposure for more than one year, according to the Centers for Disease Control and Prevention. The short answer: When in doubt, more is more. Even though applying SPF 100 instead of SPF 50 only boosts your protection slightly, that buffer can add up over time and “reduce the accumulation of chronic UV damage that is linked to non-melanoma skin cancer and aging,” Dendy Engelman, MD, board-certified dermatologic surgeon at Medical Dermatology & Cosmetic Surgery in New York City.

This is obviously a prevalent problem for a variety of manufacturers and a variety of brands," Light says, adding that the FDA will most likely issue a recall for more batches than Valisure requested, simply because it only had so many resources to run initial tests. So, while higher is better in that sense, a higher SPF won't protect you for a longer amount of time, says Green. Using a high SPF such as 100 can give you a false sense of protection, because people assume that SPF 100 allows them to stay in the sun for a longer period of time without reapplying, she explains. "Regardless of whether you are using SPF 30 or SPF 100, you must reapply sunscreen every two hours." But the higher the SPF, the lower the UVA protection.
