The permanent Botox smile may be on the way out. The FDA is expected to approve Evolence for use in the US this spring. Evolence lasts longer and studies have shown that the effects last longer and are "softer" than Botox. Already in use in Europe, Evolence treatments can last up to 12 months.
Implications - There is a growing demand for appearance-enhancing products that don't require surgery, but to date, most effects have been short-lived, which has caused some budget-conscious consumers to reconsider. The ability of a smile-enhancing injection to last longer than before may be the extra push some hesitant consumers need when weighing the costs and benefits of physical beauty enhancement.
