BOSTON -- Nearly 11 million people had plastic surgery in the U.S. last year. The No. 1 procedure was breast augmentation.

NewsCenter 5's Heather Unruh reported Thursday that now that silicone implants are back on the market, some women are eager to swap out their old implants.

Jen Seidel-Walsh is a makeup artist. Like many women, she feels a certain pressure to be perfect -- especially after having three kids.

"I just wanted to look good again. I wanted to feel that feeling I had when I was younger -- just for myself. Not for anybody else but myself," she said.

Four years ago, she got saline breast implants. They were the only choice at the time. She said that she was happy with them -- for a while.

"I've lost weight since then, so I lost a lot of fat underneath the skin, which kind of shows a little more of the detail of the saline bag," Seidel-Walsh said.

Saline breast implants can feel hard under the skin. The newly Food and Drug Administration-approved silicone gel implants don't leak when cut in half, and they're softer. Seidel-Walsh said that it was exactly what she wanted.

Dr. Dean Kane said women are switching out their implants for two reasons.

"One is because they want a softer implant, and two is they want a more natural look and not the round appearance of a firm saline implant," Kane said.

Kane performed Seidel-Walsh's procedure. Looking at her before shot, the definition of the saline implants is apparent. After the switch, she has a softer, more natural look.

"I am completely thrilled. It's a huge difference -- huge," she said.
