Skin cancer is one of the most common, yet preventable, cancers. The key to prevention? Shielding your skin from harmful UV radiation with a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher.
The U.S. Food and Drug Administration highlights that using a quality sunscreen with strong UVA and UVB-blocking ingredients can reduce wrinkles, prevent sunburn, and lower your risk of skin cancer. However, even the best sunscreen won’t protect you if it’s not used correctly. Here are five common mistakes people make when applying sunscreen:
1. Applying Too Little Sunscreen
Many people underestimate how much sunscreen they need, resulting in uneven coverage and reduced SPF protection. To get the full SPF benefits, generously apply at least one ounce of sunscreen to cover your entire body on sunny beach days. For your face, the Skin Cancer Foundation recommends using a coin-sized amount. The American Academy of Dermatology (AAD) advises that most adults need about a shot glass full of sunscreen to adequately protect their bodies.
2. Skipping Sunscreen on Cloudy Days
A common misconception is that sunscreen is only necessary on sunny days. However, up to 80% of UV rays can penetrate through clouds, making daily sunscreen application essential, regardless of the weather. Protecting your skin from these rays every day significantly reduces the risk of skin cancer.
3. Missing Important Areas
It’s easy to overlook certain areas when applying sunscreen, such as the ears, neck, and the tops of feet. These spots are just as vulnerable to UV damage, so make sure to cover all exposed skin.
4. Not Reapplying Often Enough
Sunscreen doesn’t last all day. To maintain protection, apply sunscreen 15 minutes before going outside and reapply every two hours, or immediately after swimming or sweating. Even water-resistant sunscreens are only effective for 40 to 80 minutes once they come into contact with water.
5. Neglecting to Reapply After Sweating
If you've been sweating heavily, you need to reapply sunscreen to maintain protection. But first, make sure to cleanse your skin—applying sunscreen to a dirty face can clog pores and lead to breakouts.
To safeguard your skin from sunburn and long-term damage, opt for a sunscreen that offers both UVA and UVB protection. Look for products containing zinc oxide or titanium dioxide, which effectively block both types of rays. By avoiding these common mistakes, you can ensure your sunscreen is working its best to keep your skin healthy and safe.
