Debunking Common SPF Myths: Your Guide to Smarter Sun Protection

Did you know that 90% of visible signs of aging are caused by sun damage? And up to 20% of the sun’s harmful rays can penetrate your skin—even on a cloudy day! The truth is, SPF is your BFF and should be worn year-round. Yet, many people still fall for common SPF myths that leave their skin vulnerable. Today, we’re setting the record straight on sun protection so you can make the best choices for healthy, youthful skin.

Myth #1: A Little Sunscreen Goes a Long Way

One of the biggest misconceptions about sunscreen is that a small amount will do the trick. In reality, most people don’t apply enough to get the full SPF protection listed on the bottle. For your face alone, you need about a nickel-sized amount, and for your body, about a shot glass full. Reapplying every two hours—more frequently if you’re swimming or sweating—is essential to maintaining protection.

Myth #2: All Sunscreens Are Created Equal

Not all sunscreens are the same, and choosing the right one matters. Mineral sunscreens, like Coola Mineral Sunscreen, provide superior protection by physically blocking UV rays, rather than absorbing them like chemical sunscreens. Plus, Coola is certified B Corp, reef-safe, and eco-conscious, making it a fantastic choice for both your skin and the environment.

Another favorite is Tizo Sunscreen, a high-quality mineral SPF that offers broad-spectrum protection while leaving no white cast—a common concern with mineral formulas. Tizo’s Sunscreen/Primer is perfect under makeup, providing a smooth base while ensuring your skin stays protected.

Myth #3: Makeup with SPF Is Enough Protection

While it’s great that many foundations, powders, and tinted moisturizers include SPF, they’re not enough on their own. Most people don’t apply makeup in thick enough layers to reach the full SPF protection level stated on the packaging. However, SPF makeup is a great way to boost your protection and reapply throughout the day.

One of our favorites for extra sun defense is Jane Iredale Mineral SPF, a skincare-infused makeup line that’s designed to nurture and protect the skin. Often called The Skincare Makeup, Jane Iredale products are made with skin-loving ingredients like antioxidants, botanicals, and minerals that offer clean, non-irritating coverage. Mineral makeup is also better for your skin because it allows it to breathe, won’t clog pores, and provides additional sun protection with naturally occurring SPF from titanium dioxide and zinc oxide.

The Bottom Line

SPF isn’t just for sunny days at the beach—it’s an everyday essential. By choosing high-quality mineral sunscreens like Coola and Tizo, and enhancing protection with Jane Iredale’s SPF makeup, you’re giving your skin the best defense against premature aging and damage. So, lather up, reapply often, and make sun protection a non-negotiable part of your skincare routine!
