Refresh your eyes and restore youthful definition with an upper blepharoplasty. This precise eyelid procedure removes excess skin and restores contour, revealing brighter, smoother eyes that look naturally rested and beautifully in harmony with your features.


The most common chief concern of patients with aging eyelids is a sad and tired look. Both men and women frequently see this as one of the first signs of aging. Sometimes it is genetic; patients relate that their mom or sister had their eyelids done. Motivation to stay competitive in the workforce is another worry.
If the main goal of upper eyelid surgery in Denver and Fort Collins is to look younger, then correction of volume loss may be the primary target.
If skin excess is the main concern, surgical correction may be the correct choice.
If skin quality and mild laxity are present, laser resurfacing can tighten skin, remove wrinkles, and even create a lifted brow.


If colleagues mention that you look tired or sad, correction of this look may be possible with treatment. For many, the concern can be vision-related. Droopy upper eyelids can restrict peripheral vision. Ladies may be interested in the ability to see the eye makeup that they have put on.
For some, the ‘crepey’ quality of skin is more of a concern than skin excess. In the lower lid region, the main complaints are dark circles or bulging fat pads, in addition to a constantly tired appearance.

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.”

“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.

I can’t say enough about Dr. Duncan and her staff! I was made to feel comfortable every step of the way, and I genuinely had a great time through the whole process, even during surgery. Diane Duncan exudes confidence in her craft, and it is displayed in her work, experience, and reputation worldwide. I have never had any type of surgery, and Dr. Duncan, the nurses, and staff members were wonderful on the day of surgery (and throughout the process) and set me completely at ease. I am VERY pleased with my experience and would recommend Dr. Duncan to anyone interested in Plastic Surgery.

“From the beginning to the end, my experience with Dr. Duncan and staff was over-the-top exceptional. Everyone was helpful, knowledgeable, and very friendly. I feel the work I had done was perfect and that Dr. Duncan achieved a very natural look for my body. I highly recommend PSA and will be visiting them again in the near future for other procedures.”

“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!”
