Loose Skin After GLP-1s? How Sofwave Can Help
From the team at Nova MedSpa, serving Ankeny, Polk City, and Dubuque, Iowa
At Nova, we blend aesthetics and functional medicine, so we see the full picture of a patient's weight-loss journey, not just one piece of it. As GLP-1 medications have helped so many of our patients lose significant weight, we've also heard a new question come up again and again: what happens to the skin once the weight is gone? We want to walk through why that happens and how Sofwave fits into supporting your skin through that transition.
Why Skin Doesn't Always Keep Up With Weight Loss
Skin is elastic, but it has limits. When fat volume decreases quickly, the skin that was stretched to accommodate it doesn't always shrink back at the same speed. Collagen and elastin, the proteins responsible for skin's structure and bounce, need time and the right support to adapt to a smaller frame. This is why many patients notice looser skin around the face, neck, and arms after meaningful weight loss, even when the results are otherwise exactly what they hoped for.
How Sofwave Supports Skin After Weight Loss
Sofwave uses SUPERB (Synchronous Ultrasound Parallel Beam) technology to deliver controlled heat at precisely 1.5mm in the mid-dermis, where collagen, elastin, and hyaluronic acid are actively produced. An integrated cooling system called Sofcool protects the skin's surface throughout treatment. It's a single, in-office session with no downtime, which makes it a practical fit for patients already juggling appointments as part of a broader weight-management plan.
The clinical evidence behind Sofwave is part of why we offer it:
40+ peer-reviewed publications
68% average collagen increase confirmed by biopsy (Suh et al., 2025)
33% average elastin increase confirmed by biopsy (Suh et al., 2025)
Documented stimulation of hyaluronic acid production in the dermis
1 million+ treatments worldwide, no fat atrophy events reported in published data
7 specific FDA aesthetic clearances
Results lasting 12 months or longer from a single session
Where Weight-Loss Patients Notice Skin Laxity Most
Neck & Under the Chin (FDA-cleared: submental lifting): Addresses loose skin under the chin that becomes more noticeable once facial fat decreases
Eyebrow & Upper Face (FDA-cleared: eyebrow lifting): Supports a refreshed upper-face contour as fat pads throughout the face shift
Fine Lines & Wrinkles (FDA-cleared: facial lines and wrinkles): Stimulates collagen to help skin adapt to a new facial volume
Upper Arms (FDA-cleared: skin laxity improvement): Addresses looser skin on the arms, a common concern after significant weight loss
Cellulite-Prone Areas (FDA-cleared: cellulite appearance): May help smooth the appearance of cellulite as underlying tissue changes
Is Sofwave Right for You After Weight Loss?
Sofwave may be worth discussing at your next visit if you:
Have lost weight through a GLP-1 medication or another method and noticed looser skin
Have mild to moderate skin laxity in the face, neck, or arms
Want a treatment backed by published, biopsy-confirmed evidence
Want to support your results with no downtime
Are already working with our functional medicine team on a broader wellness plan
At Nova, Sofwave is also part of Body by Nova, our program that pairs medically supervised GLP-1 support with skin and body treatments like Sofwave, Sculptra and Kybella, so your skin can keep pace with your progress.
How to Prepare for Your Sofwave Treatment
Preparing for Sofwave is simple. Every treatment at Nova starts with a provider evaluation to make sure it's the right fit for you. Come to your appointment with clean skin in the treatment area, free of makeup and lotion, and let your provider know about any medications you take, including GLP-1s, and any recent changes in your weight so we can tailor your plan and timing.
What to Expect With Sofwave at Nova MedSpa
Our advanced nurses and nurse practitioners build a plan around your specific goals, typically one to two sessions depending on your skin's condition. Treatment takes about 30 to 45 minutes, and the integrated Sofcool cooling system keeps you comfortable throughout. Most patients see visible change within about 4 weeks, with continued improvement up to 12 weeks as new collagen builds. There is no downtime, though the skin may appear slightly red with limited swelling for a few hours after treatment.
Weeks 4 to 12: Early visible improvement as new collagen develops
Months 3 to 6: The most noticeable stage of results
12 months and beyond: Results lasting a year or longer from a single session
Frequently Asked Questions
Q: Why does skin loosen after GLP-1 weight loss?
A: When fat volume decreases quickly, the skin that was stretched to cover it doesn't always shrink back at the same pace. Collagen and elastin need time and support to adapt to a smaller frame.
Q: Can Sofwave replace surgical skin removal after major weight loss?
A: Not always. Sofwave is best suited for mild to moderate skin laxity. Patients with significant excess skin after major weight loss may still be better candidates for a surgical procedure, which our team can help you evaluate at a consultation.
Q: What evidence supports Sofwave's results?
A: Sofwave is backed by 40+ peer-reviewed publications, including biopsy-confirmed data showing a 68% average increase in collagen and a 33% average increase in elastin (Suh et al., 2025), along with documented stimulation of hyaluronic acid production.
Q: Is Sofwave safe if I've recently lost a significant amount of weight?
A: Sofwave is designed to target the mid-dermis at 1.5mm, above the fat layer, and across 1 million+ treatments, no fat atrophy events have been reported in published data. Your provider will confirm it's a good fit for you at your evaluation.
Q: How long do results last?
A: Results can last 12 months or longer from a single treatment session, with full results typically visible within 3 to 6 months.
Q: Is there downtime after Sofwave?
A: No. Patients return to their normal routine the same day.
Q: Do I need to be on a GLP-1 medication to benefit from Sofwave?
A: No. Sofwave is appropriate for anyone with mild to moderate skin laxity, whether or not weight loss is the cause. It's simply a treatment we see a lot of interest in from our weight-loss patients specifically.
