How can we know the expiration date?

I just checked 3 bottles and tubes of sun lotion and can find no expiration dates anywhere.

(I just asked this but it didn't show up)

Must the good doctor start every sentence with, "So..."? It maddening!

How can we know the expiration date?

I just checked three bottles of sunlotion -- no expiration dates.

Thank you for having this guest. She is providing precise and useful information. I had a two sunburns in adolescence and one in adulthood and I have a looming fear of developing skin cancer. So far, ok.

So, we're supposed to slather loads of suntan lotion on every two hours, become vitamin D deficient and then take pills to replace the the vitamin D we're no longer producing. Excuse me, but this sounds bass ackwards. Humans have been in the sun for millions of years. If you don't roast yourself on the beach or pool or rooftop and take normal precautions, the likelihood of you're getting cancer is more likely genetic than anything else.

What is the actual risk of skin cancer? I HATE wearing sunscreen -- it makes me sweat, burns my eyes, makes me very uncomfortable. Plus it's expensive!

There's a French sunscreen that claims there's a third type of UV between A and B, and that they alone protect against it. Is this true?

Thinning of the ozone layer is unrelated to global climate upset. It can be caused by CFCs & other chemicals humans put into the atmosphere, & also (short-term) by volcanic eruptions. It's a different issue, & the 2 shouldn't be confused.

However, with the recent volcanic eruptions, I'm wondering if we need to be aware of when the ozone layer is thinner so we can take more precautions against UV.

Do expiration dates on sunscreens matter?

What about spray sunscreen compared to lotion?

There was very recent news that the incidence of nearsightedness was due to children staying indoors more rather than playing outdoors in the light/sun. What about that?

What about days that are cloudy? Years ago, I was seriously burned on an 'overcast' day, as I recall. Is this possible?

Do expiration dates on sunscreens matter?

Don't Europeans have access to better sunscreens than we do? Why?

Titanium dioxide and zinc oxide seem to produce a white powdery finish. How does a person with dark skin wear either of these? I usually use a sunscreen with avobenzone, but I'd like to use titanium dioxide or zinc oxide. What is causing that powdery look anyhow?

So we should be more concerned about UVA than UVB?

Can the FDA really be trusted? They allow so many toxic chemicals in our personal care and household products.

hello?! which oils block sun? please specify.

Does lipstick offer any sun protection to the lip?s

Are spray on tans are safe?

I'm confused?? What kind of lotions are safe to buy that are currently available? Are the labels just lying about what spectrum they cover?

Are spray on tans safe?

Are animals susceptible to skin damage from the sun as well as humans?

What is the concern over "nanoparticles" in sunscreen?

Can you please comment on laser hair removal. Is the light of the laser safe?

Last year I think I became allergic to Chapstick lip balm with SPF 30. Does that sound possible? I'm afraid to use it this summer.

1)Are spray on Sunscreens effective
2)Is wearing very shiny lip gloss a risk factor for lip cancer.
3) is sunscreen ever water proof

Hi,
Can you ask your guest where to get reliable information and recommendations for the best suncare?
thank you.

Isn't there a very effective ingredient available in the sun block in Europe which is not available here because of corporate disagreements?

Leanord, does your guest have any special recommendations as far as special precautions for babies? what is the evidence regarding early sun exposure and lifetime skin cancer rates?

Hi,

When I was a teenager, I burned badly, bled on my face, while painting houses. Is there anything I can do now, to prevent these areas from developing any problems, other than cover, wear sun block & etc?

Could you recommend some sunscreens that are safe. I was a redhead and have had basel cell carcinomas.

Leonard, when you introduced this piece, you referred to the "Federal Drug Administration". There is no such agency. There is the Drug Enforcement Administration, which handles controlled drugs, and the Food and Drug Administration; I think you mean the later.

There is a debate whether sunscreens containing Vitamin A assist in causing cancer. Any thoughts?

I would like to know how the various chemicals in sunscreen might affect vitamin D synthesis.

As the child of a skin cancer victim, I feel so sorry for everyone who was denied the necessary information on sunscreen labels for all these years. More people need to understand the role of Republicans in this shameful episode, and need to be more active about getting us the protections we need:
"High Court Nominee Admits Lobbying OMB, FDA
Posted on August 8, 2005

Supreme Court nominee John G. Roberts, Jr. conceded that he omitted records of lobbying the White House Office of Management and Budget (OMB) and U.S. Food and Drug Administration (FDA) from his other public disclosures, after Newsday uncovered the lobbying activities.

As an attorney for the Cosmetics, Toiletry and Fragrance Association, Roberts lobbied against proposed labeling regulations for sunscreen products by threatening litigation. . . . ."
