Seventy might be the new 50 if you exercise and maintain a nutritious diet โ€“ but aging affects the outside as well as the inside. Thatโ€™s why people who want a more youthful look to go along with their healthier body are heading to plastic surgeons.

Less-invasive surgical lifts and the use of longer-lasting fillers to firm up tissue are the latest cosmetic surgery trends. The use of minimally invasive fat injections increased nationally by 13 percent from 2015-16, according to the American Society of Plastic Surgeons.

โ€œThereโ€™s been a huge boom in non-invasive cosmetic procedures,โ€ said Dr. Debra Johnson, president of the Chicago-based organization. โ€œSome new products and devices are out, like different laser treatments that work under the skin, so thereโ€™s very little down time.

โ€œWe have a population thatโ€™s working longer; people arenโ€™t retiring at 65 anymore. Theyโ€™re still in the workforce and they want to continue to look energic and youthful and competitive.โ€

People as young as their late-30s are opting for some fine-tuning, said Dr. Richard Schwartz of the Palm Beach Plastic Surgery Center in West Palm Beach. Their goal is to maintain โ€œa healthy appearance,โ€ he said. โ€œTheyโ€™re choosing to have much less extensive surgery, and that gives them a subtler look.

โ€œOther people donโ€™t have any idea that theyโ€™ve had anything done; they just look good.

โ€œBut my typical patient from Palm Beach is in their 50s, 60s or 70s,โ€ he added. โ€œTheyโ€™ve got much too much loose skin for these non-surgical devices.โ€
