Preventative Benefits of Botox - Identical Twin Study

I wanted to share this often-referenced study that compared the effects of Botox on facial lines in identical twins where one twin had undergone regular Botox treatments over the preceding 13 years, and the other twin only had Botox treatments twice, several years prior to the study.

The results found that the twin treated with Botox regularly (image on the right) did not show as many of the signs of aging as her minimally-treated sister (image on left). Neither twin received treatment in the lower 1/2 of their face and a similar degree of aging was seen giving support to the belief that the differences that are seen in the upper face are related to Botox.

Of course there are many factors that can contribute to skin aging, something I highlighted in another recent post with a different study of twins. But in this study the researchers concluded that long-term treatment with Botox could in fact prevent the development of facial lines like forehead lines and crow’s feet that are otherwise more visible at rest when left untreated.
