Shedding Light on Sunscreen

Shedding Light on Sunscreen

By Rhonda Klein, MD, FAAD

If you were born in the 70s or 80s, you probably consider yourself clued up on sun care and how to stay safe. Most of this generation, and those that follow it, know the dangers of tanning beds, we wear sunglasses year-round (okay, maybe sometimes it’s to hide at school drop off) and we’d never think of letting our kids on the beach without a thick layer of SPF…and a hat that we wrestle back on at least every eight minutes. All of that knowledge aside, there is still a lot of confusion about sunscreen – which ingredients should we be choosing, and which chemicals are a no-no? Everybody seems to have an opinion and there’s no hiding from the consequences of choosing incorrectly; sun damage and premature aging on the “good end” and skin cancer on the very scary end.

Dr. Rhonda Klein shares her clinical expertise and very real-life practicality (she has 4 kids!) to help demystify the myths from the facts.


What SPF? What about scary ingredients?

According to the American Academy of Dermatology, a minimum of SPF 30 is suggested, look for broad spectrum protection that specifies UVA and UVB rays and preferably choose a water-resistant formula. But what about those nasty chemicals? Oxybenzone, avobenzone, nanoparticles – they sound scary and fail the “if you can’t pronounce it, it’s bad” rule of thought, but the reality is I put them on my kids. It would take decades of literally eating these products to be concerned about the purely theoretical risks of endocrine disruption or cancer. Unless you have sensitive skin or are applying on an infant (where we recommend sticking to plain zinc like we use on a baby's bottom), these ingredients have never been proven to be carcinogenic or dangerous.


So if SPF 30 is enough, why are there so many higher numbers available on the shelf?

A recent study has shown that sunscreens with a rating of SPF 100 may be more effective than ones rated SPF 50...even though the Food and Drug Administration says that any SPF above 50 offers no additional protection. The findings of the 199-participant study were published recently in the Journal of the American Academy of Dermatology and the really great thing about this study is it was designed to be “real world.” The participants skied in Vail, CO and were responsible for applying half their faces in SPF 50 and the other half in SPF 100. More than 55 percent of the subjects were burned more on the SPF 50 side than on the SPF 100 side. Sunburn severity was also worse on the SPF 50 side.

This is probably pretty shocking to most people, who assume that a swipe of SPF 50 in the morning means total coverage with no chance of sunburn - and this just isn’t the case. According to the Skin Cancer Foundation, one in five Americans will get skin cancer in their lifetime, so buy high, apply more than you think and keep reapplying. Also, it’s never too late to start daily sun protection; we get more than 50% of our cumulative sun exposure after the age of 40!

**Sunscreen sticks are great for reapplication on the face, especially near the eyes. For or all of us bargain shoppers, the Trader Joe's zinc sunscreen stick is a steal at $5.99; while not as cosmetically pleasing (it leaves a white residue), it is a great addition to camp bags for the little ones to use on their faces**
