Summary

TLDRDermatologists Dr. Jeremy Brauer and Dr. Michelle Henry debunk common sun care myths, emphasizing the importance of broad-spectrum sunscreen with SPF 30 or higher for adequate UVA/UVB protection. They refute the idea of 'healthy tans,' warn of the dangers of even one sunburn, and highlight the need for comprehensive sun protection, including shade and protective clothing. They also address the misconception that sunscreen alone is sufficient, explaining that sun damage can occur indoors and in the shade.

Takeaways

  • ☀️ SPF is crucial for UVB protection, but also look for broad-spectrum coverage for UVA rays.
  • 🌡️ Higher SPF doesn't always mean better; SPF 50 blocks about 98% of UVB rays, while SPF 100 only blocks 99%.
  • 🚫 'Healthy tan' is a myth; any tan indicates skin damage and increases skin cancer risk.
  • 🏖️ Base tans offer minimal protection, approximately equivalent to SPF 3, and increase skin cancer risk.
  • 🌤️ You can still get sunburned in the shade due to reflections from various surfaces.
  • 🏠 Sunscreen is necessary indoors near windows or while driving, as UVA rays can penetrate.
  • 🤲 Don't forget to apply sunscreen to often-missed areas like the backs of hands, tops of feet, and lips.
  • 🔥 Getting sunburned even once can significantly increase your risk of skin cancer.
  • 👨‍⚕️ Regular skin checks by a dermatologist are important for early detection and prevention of skin cancer.
  • 🌡️ The sun's UV rays are strongest during peak hours, typically 10 a.m. to 3 p.m., not necessarily when it feels hottest.
  • 🧴 Everyone, regardless of skin color, needs sunscreen; darker skin provides some natural protection but not complete immunity to UV damage.

Q & A

  • What is the myth about SPF that Dr. Michelle Henry debunks?

    -Dr. Henry debunks the myth that a higher SPF is always better. While SPF is important for protecting against UVB rays, it's also crucial to have broad-spectrum UVA/UVB protection. Additionally, beyond SPF 50, the increase in protection is minimal.

  • Why is the idea of a 'healthy tan' considered fake news by dermatologists?

    -Dermatologists consider the concept of a 'healthy tan' as fake news because UV light is a known carcinogen, and there is no safe dose of UV light. Tanning indicates skin damage, which increases the risk of skin cancer.

  • How does Dr. Henry suggest achieving a tan safely?

    -Dr. Henry recommends using sunless tanning creams, lotions, and sprays to achieve a tan safely without exposing the skin to harmful UV rays.

  • What is the truth about getting a base tan providing protection from sunburns?

    -A base tan provides minimal protection, roughly equivalent to an SPF of 3, which is not significant. It does not prevent sunburns effectively but increases the risk for skin cancer and accelerated aging.

  • Can you get sunburned in the shade?

    -Yes, you can get sunburned in the shade because UV rays can reflect off surfaces like sand, snow, and concrete, even under shade structures.

  • Why is it a myth that you only need sunscreen when going outside?

    -It's a myth because you can still get exposure to UVA rays indoors, especially near windows, and while driving in a car. UVA rays can penetrate through glass and clouds.

  • What areas of the body are often overlooked when applying sunscreen?

    -Areas often overlooked include the backs of hands, tops of feet, lips, parts of the scalp, chest, behind the legs, and underneath the chin.

  • How does getting sunburned once impact the risk of skin cancer?

    -Getting sunburned even once can increase the risk of skin cancer. Having five sunburns before the age of 18 can double the risk for melanoma.

  • Why is it important to have regular skin checks by a dermatologist?

    -Regular skin checks help identify any potential issues early and allow for preventive measures or treatment. They also provide an opportunity to discuss skin care and sun protection strategies tailored to the individual.

  • Is it true that the sun is strongest when it's hottest?

    -No, the sun's UV rays are strongest during midday hours, typically from 10 a.m. to 3 p.m., not necessarily when it feels hottest, which is often later in the afternoon.

  • Do people with darker skin types need sunscreen?

    -Yes, everyone needs sunscreen regardless of skin type. Darker skin has some natural protection from melanin, but it's not enough to prevent sun damage or skin cancer.

  • How do chemical and physical sunscreens differ in their mode of action?

    -Chemical sunscreens work by bonding with the skin and converting UV light to heat, while physical sunscreens, like those containing titanium dioxide and zinc oxide, lay on top of the skin and reflect UV light.

  • Why is it not recommended to mix sunscreen with other skincare products?

    -Mixing sunscreen with other products can dilute its effectiveness and may not provide the intended SPF protection. It's best to apply sunscreen as a standalone product for optimal results.

  • Does using sunscreen prevent the body from getting enough vitamin D?

    -Sunscreen does not completely block sunlight, so some vitamin D can still be synthesized. However, it's recommended to get vitamin D through other means like supplementation or diet to avoid skin cancer risks.
