My body looks as well as it should 6 weeks after surgery and I can't wait to see the final results in several months. I would definitely choose her again.”

NEO resolving chronic back pain

“I had chronic back pain before I started EmSculpt Neo treatment. I could never bend over without having a lot of pain. Now, even three months after treatment, I can move freely without issue! I can lie on the floor or the couch, do workouts, and stand for long periods of time without any back issues whatsoever. I highly recommend this treatment.”

Most of my life, I was happy with my C-cup breast size. But after having four children and turning 41, my breasts were small and sagging and barely an A-cup! I made a consultation appointment with Dr. Duncan because of her 20+ years of experience, and at my initial consultation, I immediately felt comfortable. Dr. Duncan listened to me and took the time to answer all of my questions. I consulted with two other plastic surgeons, who both recommended an implant size larger than that of Dr. Duncan. I would have been very unhappy with breasts larger than I have now!! I definitely made the right choice in selecting Dr. Duncan for my breast augmentation.

Everything went smoothly and healed up great

“I had a rhinoplasty with Dr. Duncan about a month and a half ago. Everything went smoothly and healed up great! I had to get a septoplasty as well with a different doctor, and she was so great with accommodating for that. Little to no bruising anywhere, just a scar where my nose was opened, but with scar cream it is fading slowly. I love my new nose!”

About Our Abdominal Body Contouring Techniques

Traditional liposuction for the abdomen is a good solution for young patients who have a mild to moderate region of fat excess and have no skin laxity.

For patients who have larger trouble spots, those with a bit of loose skin, and some who have had previous treatment and need a touch-up, Dr. Duncan offers many alternatives, such as radiofrequency-assisted liposuction, laser-assisted liposuction, and J-Plasma.

Her ability to tighten the skin by up to 33% without requiring skin removal is the primary reason patients seek Dr. Duncan’s services for liposuction.

Abdominal Contouring Real Patient Story

This 22-year-old had a growth spurt, and developed a localized fat deposit along with stretch marks in her lower abdomen. Traditional liposuction (SAL) would leave her with sagging, irregular skin in the treatment region.

Left: 22-year-old with an abdominal bulge. Results, right, 6 weeks after liposuctions and skin tightening with BodyTite (if she had been treated with traditional liposuction, there would have been sagging skin in the lower abdominal region).

Common Questions About Abdominal Contouring

I’m older and have lost tone in my tissue as I’ve aged. I’m worried that if I have fat removed, the skin left behind will just sag and wrinkle.

52-year-old before treatment and 3 months following RFAL of the abdomen with BodyTite

This can certainly happen. Dr. Duncan’s special area of research is correcting the tone as well as reducing the laxity of skin without having to cut skin or soft tissue out. Her nine years of work have resulted in our ability to offer excellent outcomes with minimal downtime for the treatment of abdominal contour problems for both men and women through abdominal contouring and plastic surgery.This 52-year-old worked hard to tone and flatten her stomach. Her husband told her she looked great. However, she disliked the localized fat around her belly button. She saw the protrusion in clothing when wearing a swimsuit. Her skin was a bit lax, so she opted for RF-assisted liposuction of the abdomen.52-year-old before treatment and 3 months following RFAL of the abdomen with BodyTite

I’ve seen two other surgeons who have told me I need a tummy tuck. I just don’t want this much surgery. Can I get some improvement with liposuction? They say my skin would sag, and it would not look good without cutting skin out.

Abdominal protuberance before surgery and 3 months after RFAL with BodyTite by Dr. Duncan

There are certainly situations in which liposuction plus minimally invasive skin tightening can give a satisfactory result. The general rule is that if the skin contraction needs to be more than 33%, some skin excision will be required. Simple liposuction will only achieve 8% skin surface area reduction, and there is no “boost” to the skin or framework of lax underlying fat. Dr. Duncan prefers RF-assisted liposuction (33% skin contraction) over laser-assisted liposuction (15% skin contraction).

I am a middle aged man, and I want to lose my beer belly. I’ve quit drinking beer, but the fat just won’t go away. I’ve seen a plastic surgeon who told me this was omental fat located inside the abdomen, and I’d have to have big surgery to remove it. His advice was diet only

48-year-old man before surgery and 8 weeks after RFAL by Dr. Duncan with BodyTite

Dr. Duncan will check to see if there is some subcutaneous fat that can be corrected with liposuction. In men, her favorite combination is BodyTite plus J Plasma. BodyTite can create directional shaping, as you see below. By adding J Plasma, there is immediate skin contraction, so results can be seen within 24 hours.

I want improvement, but I only have 4 days to recover. After the RF liposuction procedure, when can I go back to work?

Most of our Fort Collins patients can return to a non-strenuous job after 4-5 days. We do recommend avoiding extreme range of motion as well as contact or impact sports for about 6 weeks, in order to optimize the smoothness of the results. You will need to wear a compression garment in most cases, so the skin molds down smoothly.
