Your Sculptra liquid facelift should continue to make you look volumized and lifted for about two years. However, because you are a lean runner and all of us lose an additional teaspoon of fat per year, I usually recommend a maintenance treatment once per year. You wouldn’t need 9 vials at this point, usually just one or two. Receiving yearly maintenance treatment, essentially “topping off the gas tank”, will keep you full and youthful for years. If you’d like to bolster collagen production, you could begin to get regular light chemical peels or non-invasive laser treatment to treat sun damage and keep the surface looking smoother. Also be sure you are on a medical-grade skin-care regimen, and always wear sun protection and a hat when outdoors — including when you’re on your training runs. Please find a board-certified dermatologist to work with you so that your skin will continue to be healthy and strong over the years.
