Using sunscreen correctly is essential for protecting your skin from harmful UV rays. But according to dermatologist and SLMD Skincare founder Sandra Lee, MD (aka Dr. Pimple Popper), many people make common mistakes that reduce its effectiveness. From premature aging to skin cancer, the consequences of these errors can show up in your skin health. Here, she highlights the top 10 sunscreen mistakes you might be making — and how to fix them.
#1 Using insufficient amounts of sunscreen
Most people apply less than the recommended amount of sunscreen. You should use at least a shot glass worth (about one ounce) for your entire body and a nickel-sized amount for your face. This ensures that you're getting the full SPF protection indicated on the product label.
#2 Not reapplying frequently enough
Sunscreen needs to be reapplied every two hours, or more often if you are swimming or sweating. This ensures continuous protection from UV rays. Even water-resistant sunscreens lose their effectiveness after extended exposure to water and sweat.
#3 Using expired sunscreen
Expired sunscreen can lose its effectiveness. Always check the expiration date and store sunscreen in a cool, dry place to maintain its efficacy. Sunscreen ingredients can degrade over time, reducing their ability to protect your skin from UV damage.
#4 Applying sunscreen right before sun exposure
Chemical sunscreen needs about 15-30 minutes to fully absorb into the skin and become effective. Apply it before going outdoors to ensure your skin is protected from the start. This allows the active ingredients to bind to your skin properly, providing a barrier against UV rays.

#5 Relying solely on makeup with SPF
Makeup with SPF is often not enough on its own to provide adequate sun protection. Layer it over a broad-spectrum sunscreen for best results (try: SLMD Daily Moisturizer with SPF 15). Makeup typically isn't applied in a thick enough layer to offer the full SPF protection indicated on the label.
#6 Missing commonly forgotten areas
Don't forget to apply sunscreen to often-missed spots like the ears, back of the neck, tops of the feet, and the back of your hands. These areas are just as susceptible to UV damage and can develop sunburn and skin cancer if left unprotected.
#7 Believing “water-resistant” means “waterproof”
No sunscreen is completely waterproof. Water-resistant sunscreens still need to be reapplied every 40-80 minutes when swimming or sweating. The FDA no longer allows sunscreens to be labeled as waterproof or sweatproof because all sunscreens eventually wash off.
#8 Assuming you don’t need sunscreen indoors or in cars
UV rays can penetrate windows, so it's important to wear sunscreen even when you're indoors or driving. UVA rays, which contribute to skin aging and cancer, can penetrate glass and affect your skin.
#9 Not using sunscreen on cloudy days
Up to 80% of UV rays can penetrate clouds. Sunscreen should be worn daily, regardless of the weather. Overcast conditions can often lead to a false sense of security, increasing the risk of UV exposure.
#10 Not shaking the sunscreen bottle
Ingredients in sunscreen can separate over time. Shake the bottle well before each use to ensure even distribution of the protective ingredients. This ensures that the active components are mixed properly and provide uniform protection across your skin.
Dr. Lee's Last Word
Avoiding these common sunscreen mistakes can make a big difference in protecting your skin from harmful UV rays. By applying the right amount, reapplying regularly, and covering all the necessary areas, you’ll keep your skin healthier and safer. Remember, these small changes in your routine can help you enjoy the sun responsibly and keep your skin looking great for years to come.
