Traditionally, it’s always been something for people in their middle ages to “iron out” a few wrinkles, however, a leading expert has suggestion that using it as a preventative method is always acceptable.

The text, published online in the JAMA Dermatology site, states that it is “rarely too early” to start the “conservative and thoughtful use of neuromodulators [i.e., Botox], fillers and non-invasive energy-based treatments.”

“It’s been clearly shown for a long time that frown lines, forehead furrows and crows’ feet are due to repetitive folding of skin from normal expressions,” says Dr. Kenneth Arndt, a Boston-area dermatologist and co-author of the piece.

Arndt suggests that by injecting at an early stage, will avoid later wrinkles. “If you slow down the use of these muscles beginning early in adult life, the lines never develop,” he says. “Rather than going backward and fixing something that’s there, you can inhibit it from starting in the first place.”

Arndt is a dermatologist and an adjunct professor of surgery at Dartmouth Medical School. He feels that he his backed up by a 2006 study involving identical twin sisters, one used Botulinun Toxin (Brand: Botox by Allergan) regularly for 13 years and the other who didn’t. “The study shows pictures of them 10 to 15 years later and one has a smooth and attractive forehead and the other has the expression lines you’d expect with someone with normal aging,” he says.
