I want to protect my skin this summer, but the advice online is all over the place. How do I know which sunscreen is actually right for me and my family?
If social media has left you wondering whether mineral sunscreen is better than chemical sunscreen, or whether sunscreen is even necessary on cloudy days, you’re not alone. Sunscreen has quickly become a widely debated health topic online, but the truth is much simpler than you might think.
The best sunscreen is the one you’ll wear every day, says Olivia Tasho, MPAS, PA-C, of the Cheshire Medical Center Dermatology team. Below are her answers to common questions about which sunscreen to use.
What should I look for when choosing a sunscreen?
First, make sure it’s broad-spectrum with an SPF of at least 30. Broad-spectrum sunscreens protect against both UVA rays, which contribute to skin cancer and premature skin aging, and UVB rays, which cause sunburn.
The specific ingredients matter less than finding a sunscreen you’ll use consistently.
How much should I use?
Most people don’t apply nearly enough sunscreen to get the level of protection listed on the bottle.
For your face and neck, use about two finger lengths of sunscreen. For the rest of your body, you’ll need about one ounce—roughly the amount that fits in a shot glass.
If you’re spending time outdoors, choose a water-resistant sunscreen. Whether you’re swimming, hiking, gardening or simply working up a sweat, sunscreen should be reapplied every two hours and again after swimming or excessive sweating.
Should I use mineral or chemical sunscreen?
Both types are effective when used correctly.
If you have sensitive skin, eczema or rosacea, mineral sunscreens containing zinc oxide or titanium dioxide are often the best choice. People with acne-prone skin may prefer an oil-free formula, while those with normal or oily skin can generally use chemical and hybrid sunscreens without issue.
Is sunscreen enough to keep me protected?
No. Sunscreen is only one piece of sun protection. UPF clothing, a wide-brimmed hat that covers your ears, UV-blocking sunglasses, and seeking shade during peak sunlight hours—typically between 10 a.m. and 4 p.m—all help reduce harmful UV exposure.
Sun exposure happens even when you aren’t spending the day at the beach. A quick walk with the dog, running errands, or eating lunch outside all add up over time. That’s why I encourage patients to make sunscreen part of their daily routine, rain or shine.
When it comes to protecting your skin, don’t overthink it. I always tell patients to find one that you like and can be consistent with. That’s the best way to keep your skin healthy this summer and all year long.
