A cheeky way to prove seriousness of sun damage

Take a good, hard look at this image. Can you determine which derriere belongs to a 25, 35, 45, 55, and 65 year old? 

Now take a look at this image. Can you identify which face belongs to that of a 25, 35, 45, 55, and 65 year old?

 

My patients often tell me that their friends make fun of them for being so diligent about sun-protection, and to those that don't know-- I suppose applying SPF 50 all winter long can seem silly? However, to brilliantly demonstrate the subversive effects that sun damage has on our skin, day-in and day-out, Julie Kenner, M.D., PhD recently constructed a very simple experiment that was published in Cosmetic Dermatology. 

The "Cheek Quiz" consisted of five women, each in different decades of life (20's, 30's, 40's, 50's, and 60's) that agreed to have both their faces and their bare buttocks photographed. 

The sets of pictures were randomly mixed, and then 50 participants were asked to look at the pictures, and identify which picture went with which age. 

Whereas over 75% of the participants were able to correctly identify the women's age group based on their facial pictures, less than 5% were able to guess the women's age based off the appearance of their buttocks. (Can you? Answers are at very bottom.)

The organizers of this experiment were pleased with their findings, because it provided such a clear example of the importance of sun protection. The faces, which are exposed to UVA and UVB radiation all year long, showed the distinct passage of time, whereas the skin of the rear-ends look almost indistinguishable from each other, despite the chronological age, because that skin is always covered up and protected from the sun's damaging rays. (The presence of cellulite provides the only clue about the age of the rear-ends.)

This goes to show that the signs of aging are mostly caused by sun damage, and it is a unique concept to think that we'd all be better off if our face's looked more like our buttocks... 


It probably goes without saying, but daily sun protection is vital-- whether it is winter and you are in the office all day, or it is summer and you're spending time at the beach. Your skin is being exposed to harmful UVA and UVB rays all the time, whether you're cognizant of it or not. It is in your best interest from both a health and aesthetic stand-point to nip the danger in the bud(dock?) and simply protect your skin. Solise sun-wash is a body wash with built in SPF, (so that once you're dried off from the shower or bath, you're already covered in a mineral based physical sun block) that makes your first step towards sun protection something you barely even think about, and SkinCeuticals makes an array of wonderful sunscreens that can be used year-round with no greasy/shiny/bad-smelling after-effects.
