Introduction: Why Sunscreen is Trending This Summer
This summer, sunscreen has reached an all-time high as one of the most searched topics in the U.S. With increased awareness about skin cancer and the damaging effects of UV rays, more people are prioritizing sun protection. As the temperatures rise, so do the questions surrounding the use and effectiveness of sunscreen.
In this article, we’ll address the top sunscreen-related questions trending this summer, providing the information you need to protect your skin while enjoying the sun. From the basics like SPF to whether sunscreen can prevent tanning, we’ve got you covered.
Does Sunscreen Expire?
Keyword Focus: Does sunscreen expire?
Yes, sunscreen does expire. Most sunscreens have an expiration date printed on the bottle, typically ranging from two to three years after production. Using expired sunscreen can reduce its effectiveness, meaning you won’t get the full protection against UV rays. If your sunscreen doesn’t have an expiration date, you can assume it’s effective for up to three years from the date of purchase.
Pro Tip: Store your sunscreen in a cool, dry place to extend its shelf life. If the texture or smell changes, it’s best to replace it.
Does Sunscreen Prevent Tanning?

Sunscreen is designed to protect your skin from the harmful effects of UV radiation, but it doesn’t completely prevent tanning. Sunscreen with a high SPF can significantly reduce the amount of UVB rays that reach your skin, which are responsible for sunburn and, to some extent, tanning. However, some UV rays still penetrate the skin, leading to a gradual tan. The higher the SPF, the more protected you are, but no sunscreen can block 100% of UV rays.
Fun Fact: For those looking to avoid tanning altogether, consider using a sunscreen with broad-spectrum protection and reapplying it every two hours.
What Does SPF Stand For?
Keyword Focus: What does SPF stand for?
SPF stands for Sun Protection Factor. It’s a measure of how well a sunscreen will protect your skin from UVB rays, the kind of radiation that causes sunburn and contributes to skin cancer. The SPF number indicates how long you can stay in the sun without getting burned compared to if you weren’t wearing sunscreen. For example, SPF 30 means you can stay in the sun 30 times longer than without protection before burning.
Quick Tip: SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. Higher SPF offers slightly more protection but no sunscreen can block 100% of UVB rays.
How Long Does Sunscreen Last?

Sunscreen typically lasts about two hours after application. Factors like sweating, swimming, and toweling off can decrease its effectiveness, so it’s important to reapply every two hours or immediately after getting wet. Water-resistant sunscreens offer protection for about 40 to 80 minutes in the water, but they still need to be reapplied regularly to maintain full protection.
Best Practice: Apply sunscreen 15 minutes before going outside and reapply frequently, especially during prolonged sun exposure.
Is Sunscreen Bad for You?
Keyword Focus: Is sunscreen bad for you?
Sunscreen is not bad for you; in fact, it’s essential for protecting your skin from the harmful effects of UV radiation, which can cause skin cancer, premature aging, and sunburn. However, there have been concerns about certain chemical ingredients in sunscreens, such as oxybenzone, which may cause allergic reactions or have potential environmental impacts.
Health Tip: If you’re concerned about chemical sunscreens, opt for mineral sunscreens that contain zinc oxide or titanium dioxide. These ingredients sit on top of the skin and reflect UV rays without being absorbed into the body.

With the summer sun at its peak, sunscreen is more important than ever. Whether you’re spending time at the beach, hiking, or just enjoying the outdoors, protecting your skin from UV rays should be a top priority. Sunscreen not only helps prevent painful sunburns but also reduces the risk of skin cancer and keeps your skin looking youthful by preventing premature aging caused by the sun.
Quick Tips for Sunscreen Use:
- Choose Broad-Spectrum Protection: Ensure your sunscreen protects against both UVA and UVB rays.
- Use Enough Sunscreen: Most people don’t apply enough—use about an ounce (a shot glass full) for your entire body.
- Don’t Forget Your Lips: Use a lip balm with SPF to protect your lips from sun damage.
