According to an annual report on plastic surgery procedures, there were 15.9 million surgical and minimally-invasive cosmetic procedures performed in the United States in 2015. This is a 2% increase from the year prior, and that trend has continued in the past two years.

However, the growth in plastic surgery is attributed to an unlikely demographic: plastic surgery is on the rise amongst dads in the United States. In recent years a growing number of dads are booking surgical and non-invasive cosmetic treatments.

Dr. Doris Day, a board-certified dermatologist in New York City, told Fox News that the limited downtime on modern plastic surgery treatments is one of the causes.

“The fact that we have so many treatments now that have little-to-no downtime and are minimally to non-invasive, it’s really opened up the market to men,” Dr. Day said.

According to a report by the American Society for Aesthetic Plastic Surgery, there has been a 325% increase since 1997 in the number of male cosmetic procedures performed.

The most common procedures men seek out are typically Botox, Kybella, and fillers, Day said.

“With this combination approach, you can very naturally rebalance and help somebody age very successfully and look their best, but no one will know they’ve done anything.”

The increased visibility on social media and celebrity obsession likely also plays a role in the number of dads signing up for male plastic surgery. Almost 13% of all facial plastic surgeons reported an increase in patients requesting celebrity-approved procedures in 2014. This was an increase from the previous year by 3%, according to a report by the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS).

Experts still recommend that men, like women, should do their research and find a qualified, board-certified, surgeon before opting for treatment. They should also ask about his or her training, potential side effects, and understand that the results can vary.

Day believes that the patients should also know exactly what could go wrong beforehand so they can prepare for any possibility.

“Every procedure has risks that can include bruising, scarring and even blindness,” Day warned.
