May is Skin Cancer Awareness Month, a good excuse to brush up on sun protection knowledge. If you stop reading right here, just know that a moisturizer with SPF is a must every single day, from January 1st to December 31st. This will not only prevent skin cancer, but it will ensure that you age more gracefully.
Continue reading to refresh your SPF knowledge.
What is SPF? SPF = Sun Protection Factor. The number tells you how long the sun’s UVB rays would take to redden your skin if you apply the sunscreen exactly as directed compared with the amount of time without sunscreen. So, if you use an SPF 30 product properly, it would take you 30 times longer to burn than if you used no sunscreen.
“SPF Math”. SPF 15 blocks about 94% of UVB rays; SPF 30 blocks 97% of UVB rays; and SPF 45 blocks about 98%
UV rays are bad. UV rays lead to melanoma and 90% of signs of skin aging. Wear a moisturizer with SPF every day. Avoid laying out in the sun between the hours of 11 am and 4 pm when the sun is strongest. You will get a tan from being in the shade… And please do not use tanning beds.
UV rays are bad in different ways. UVA and UVB rays are both harmful. UVA rays cause wrinkling and skin aging. UVB rays cause sunburn and skin cancer. This is why you need to use a broad-spectrum SPF (meaning one that protects from both UVA and UVB rays).
Wear SPF even when indoors. UVA rays penetrate through glass windows. Let me say it again: wear SPF every day, even when you plan on staying inside all day.
Chemical versus physical. Chemical sunscreens absorb UV rays. Physical sunblocks block UV rays. Both are better than not wearing sunscreen.
Vitamin D. Yes, we all need vitamin D. No, this is not a reason not to wear sunscreen every single day.
Please wear sunscreen (for example our Protective day cream SPF 23). Every. Single. Day. Thank you!
As I look forward to my last weekend at the beach this coming weekend, I cannot but help to think about my two grandmothers, one from an Italian farming family, the other from a Swiss-German pastor family. They did not agree on many things, but they did agree on one thing: a suntan is inelegant, and a sunburn is downright offensive. Between them and my dermatologist father, with whom I have never been in so much trouble as when I sunburn my skin, I like to think I have perfected the idea of practicing “safe sun.” While this is something to think about daily, including in the dead of winter and on rainy days, it is particularly important during vacation season. If you are heading to the beach, the pool, on a boat, for one last weekend of summer, keep this in mind:
- The safest way to be in the sun is not to be in the sun. In particular in between the hours of 11 and 3 pm, stay in the shade. You will still get some color, I promise. If you hate the shade, consider wearing a hat, to shade your face…
- Use sunscreen! Even if you are planning to be in the shade all day, sunscreen is key. A body oil with SPF 2 does not count as sunscreen… UVA and UVBs are both harmful to the skin, so make sure your sunscreen says “broad-spectrum” (the SPF value only refers to protection from UVB). Keep in mind that SPF 30, which my father recommends for “beach vacation days” will protect you from 97% of UVB. A higher SPF will increase the protection only by one percentage point: SPF 50 will increase it to 98, and SPF 75 to 99%.
- Apply sunscreen liberally. Don’t think of it as applying your moisturizer or foundation – be generous, err on too much rather than not enough. The general rule of thumb is a shot-glass worth of product for an “average-sized” body.
- Re-apply after every time you get in the water. There is no such thing as waterproof sunscreen; the FDA does recognize the term “water-resistant,” so look for that word when making your purchase, and reapply.
- Purchase new sunscreen annually, at the very least. While you may not need a new bathing suit before every summer vacation, be vigilant about the expiration dates on sunscreens. The formulations are delicate, and do break down – an expired sunscreen will not provide the protection claimed on the bottle.
- Remember the ears, back of the neck, and top of the feet (where I have gotten some of my worse sunburns). Ideally, apply your sunscreen before you put on your bathing suit, to avoid getting a burn right around where your bathing suit meets your skin.
There are lots of great sunscreens out there, I tend to find a favorite one every summer. This summer, my go-to has been by LaRoche Posay XL 50+ Sunscreen Oil, which is super easy to apply, works on face and body, and has a delightful aroma. And remember, no sunscreen is 100%. This means using an antioxidant product is key, both layered under your sunscreen and as a post-sun product, so that you instantly repair any free radical damage caused. Once again, there are many great antioxidant products on the market, my current favorite being the newest baby in the Alchimie Forever family, our Daily Defense Cream SPF23. As a first layer of protection, it is packed with antioxidants including blueberries, vitamins C and E, and edelweiss extract, and also has some chemical filters to help fight UVAs and UVBs.
Lastly, remember, you earn the skin you’re in! Protect it, practice “safe sun,” and your skin will thank you.
