Take the mystery out of choosing a sunscreen

Choosing a sunscreen can be a challenge when you are faced with endless options. The best sunscreens for your skin starts with reading the label.

Secrets of SPF

SPF (Sun Protection Factor) measures the ability of a sunscreen to protect your skin from UVB rays. The SPF number indicates how long it will take for UVB rays to redden your skin when using the sunscreen compared to not using any sunscreen at all. For instance, if you would normally burn after 10 minutes in the sun without protection, an SPF 30 sunscreen supposedly prevents sunburn 30 times longer, or about 300 minutes.

Look for a sunscreen labeled as ‘broad-spectrum,’ which ensures it guards against both UVB and UVA rays. This dual defense approach offers comprehensive sun protection, reducing the risk of sunburn, premature aging, and skin cancer.

SPF 30 is typically recommended by skin specialists. This provides ample protection when applied correctly. It blocks about 97% of UVB rays. A higher SPF only offers marginally higher protection. However, a higher SPF might be preferred for individuals with fair or sensitive skin, those prone to sunburn, or those spending extended periods outdoors.

No sunscreen provides 100% protection. Even the best ones wear off over time, especially with sweat, water, or friction. Remember to reapply it every two hours, or after swimming or excessive sweating. Don’t forget commonly missed areas like the ears, neck, and tops of feet.

Skin specialists emphasize the importance of daily sunscreen use, regardless of the weather. Even on cloudy days, UV rays penetrate through clouds.

Our Physician Assistants Mackenzie Winslow and Emily Phaneuf share some additional insights and share their favorite sunscreens.

Other factors to consider

  • Skin type. Opt for non-comedogenic formulas if you have oily or acne-prone skin. Those with sensitive skin should seek mineral-based sunscreens containing zinc oxide or titanium dioxide, which are less likely to cause irritation. Emily Phaneuf, PA-C said a sunscreen that lists these in its ingredients protects UVA and UVB light.
  • Price. Price isn’t always indicative of quality. While some pricier brands offer advanced formulations, effective sun protection doesn’t always come with a hefty price tag. Pay attention to the active ingredients rather than the brand name. Many affordable options provide excellent protection.
  • Expiration date. The FDA requires all sunscreen to retain its original strength for at least three years. After that, it’s time to throw it out.
  • Spray, stick or lotion?

Favorites

  • EltaMD products. “All of their sunscreens, specifically the facial sunscreens are fragrance-free, paraben-free, hypoallergenic, and non-comedogenic, helping to prevent acne, and are good for sensitive skin,” said Mackenzie Winslow, PA-C. “Their sunscreens protect against UVA and UVB light, and use minimal ingredients, limiting the use of chemicals on our skin. Many of their facial sunscreens also contain hyaluronic acid, which is good for maintaining good moisture in the skin, aiding in anti-aging. All of their SPF products are at least 30 SPF, which is the minimum that anybody should be wearing, no matter their skin tone.”
  • LaRoche-Possay products. If you are looking for a cheaper option that can be found in a drug store, Winslow said this brand is also suitable for sensitive skin, fragrance free oil-free non-comedogenic (non-pore clogging), allergy tested, and oxybenzone free, as well as protecting against UVA/UVB light. 
  • ISDIN products. This is Emily’s top pick for sunscreen. “While at the more expensive end of the spectrum, it is a unique product that contains both Zinc Oxide to provide adequate UVA and UVB protection as well as DNA Repairsomes, which are thought to help repair existing sun damage on the skin. It also contains other anti-aging ingredients, such as Peptides and Vitamin E, which is an important part of the skin’s antioxidant defenses and reducing harmful effects of UV radiation.”

When selecting sunscreen, prioritize broad-spectrum protection, consider your skin type, and opt for a minimum SPF 30. Price doesn’t always correlate with effectiveness, so focus on active ingredients. Remember to reapply regularly, and make sunscreen a daily habit for healthier, protected skin.
