The plastic surgeon known for developing the 24-hour “insta breast” procedure is working on a new kind of saline injection that would allow for “vacation breasts,” or a temporary impression of larger breasts for two to three weeks.

Dr. Norman Rowe, a board-certified plastic surgeon in Manhattan, said he has had insta breast customers who have been given the 24-hour enhancement but still can’t decide if implants are right for them.

"Twenty-four hours is great," Rowe told ABC News, "but it's still just 24 hours."

Rowe said that a breast augmentation that lasts for two or three weeks would be great for both special occasions, like weddings, or to allow women to understand what actual implants would be like.

"You can use 3-D imaging and put implants in bras, but it's another thing to see what the weight will actually feel like and what it will be like to live with the new breasts,” he said.

Rowe would not divulge the chemical properties that would allow for weeks-long enhancement, but he said it is something commonly used by the medical community.

These “vacation breasts,” he said, will, over time, likely cost less than the insta breasts injection, which costs $2,500. He added that the procedure would, like insta breasts, require no recovery time.

"It [the solution] could be used for more than breasts," Rowe said. "Men might want to use it for pec[toral] or calf implants."
