When you wear SPF 100, you’re more likely to think you’re invincible, and you never need to reapply it, and you never need to go in the shade, and you can stay out all day,. “Whereas when you just put SPF 30 on, you’re more likely to say, ‘Hey, I should still play it safe in the sun. I’m not invincible. In fact, I should reapply.A false sense of sun safety is an easy way to get unintended sun exposure and a nasty burn.
But there’s also quite a bit of confusion about what SPF means in the first place. For example, despite what many people believe to be true, SPF 30 is not twice as effective as 15. Instead, SPF 15 blocks 93 percent of the sun’s rays, while SPF 30 blocks 97 percent of the sun’s rays, according to the American Academy of Dermatology.Did you know that it’s illegal for sunscreen manufacturers to claim that their product is waterproof? That’s because there’s no such thing as waterproof sunscreen. It’s also the reason you should always reapply once you leave the water, or if you’ve been sweating.
Another bogus claim: lotions work better than sprays. This one’s a little tricky. When used correctly, sprays, lotions, and oils all work equally well. On the other hand, people tend to miss spots when using sprays, so it’s a good idea to spray on two coats or to rely on a formula that you know how to apply correctly.

Dermatologists say you should pick out a product labeled “broad spectrum,” which means it protects against both UVA rays, which can cause wrinkles and sunspots and UVB rays, which burn your skin. Both UVA and UVB rays contribute to skin cancer over time.
Your sunscreen should also have an SPF of 30 or greater and should be water-resistant for 40 or 80 minutes of activity (again, reapply once you leave the water).
It is quite clear now that sunscreens play a major role in protecting people from the ravages of skin cancer, “Even if you chose to avoid certain ingredients, there is a sunscreen for you out there, so use it.”
And of course, sunscreen is just one of the many ways you should be protecting your skin from damage. For optimum protection, you should also:
- Actively stay out of the sun during peak hours between 10 a.m. and 4 p.m.
- Seek shade when possible.
- Wear sun-protective clothing.
- Protect easily forgotten areas (scalp, ears, eyelids, lips and tops of feet).
