They cite an identical twin case study though where one twin was repeatedly botoxed (doesn't really tell us much about the amount of natural muscle tensing either). All authors works for P&G Beauty & Grooming. This conflict of interest is acknowledged but the BJD is a flagship journal. I'd love to get to the bottom of this and get a quantification of behaviour's supposed effect. | |

@Oliver_C: I have a copy of the paper in front of me, and this is what it has to say: ... suggesting that those who show more wrinkles with expression at any given age will tend to show more persistent wrinkles at a later age. Later on, they give an example with smiling temporary pattern that eventually evolves into permanent one, and suggest treatment of not only persistent, but temporary wrinkles when making facial expressions, so it looks that it applies to any type of temporary wrinkles. Contact me if you'd like to study the article itself and include more information in your answer.

@Ruben - I'm guessing with more wrinkles you mean "become wrinkley more quickly" ? Unfortunately I don't have access to the full paper, but I think it's reasonable to assume that it's a contributing factor. The Mayo Clinic link does say so.

| Jun 18, 2012 at 22:07 | comment | added | Ruben | Cool! But does it speak to the matter of whether smiling more actually causes more wrinkles? I thought it pretty likely that persistent wrinkles correspond to facial expression (that's why I mentioned the Botox finding). Or did they assess smile frequency somehow and this is one of the intrinsic factors mentioned in the conclusion? | |
