It’s an unfortunate fact that drooping knee skin or wrinkling around the knees just happens.

No matter your weight, size or body type, the natural course of aging causes the skin on the body to wrinkle, sag and/or droop. 

As we age, the criss-cross network of collagen weakens — this supportive scaffold no longer holds the skin in place like it once did. Additionally, we lose elastin — the skin doesn’t bounce back into place as quickly or as easily it did when we were younger. 

Prime examples? Three A-listers — all known for their clean lifestyles, exercise regimes and being in great physical shape. 

Specifically, Demi Moore is reported to have gone under the knife for a knee lift to restore drooping skin around the knee area. Additionally, the media took both Gwyneth Paltrow and Cindy Crawford to task for “old lady knees”, “kninkles”, “knobbles” and “elephant knees” in 2011.

This is exactly where Ultherapy for knees comes in. By sparking a rejuvenating process of neocollagenesis and elastin remodeling, it results in skin tightening and lifting around and above the inner, outer and upper knees.

Ultherapy is the best and only skin tightening treatment that’s FDA-cleared for the face, abdomen and arms. Currently, it’s an off-label treatment for the leg in the area around and above the knees. However, Merz, the makers of Ultherapy, have studies in the works for FDA consideration.

The reason we love Ultherapy for knees is because it’s so precise. Specifically, Ultherapy uses ultrasound energy to bypass the surface of the skin to reach clearly-defined depths under the skin.

With three transducers, depth can be adjusted to 1.5 mm, 3.0 mm and 4.5 mm beneath the skin. That’s particularly important for the skin on the legs, which tends to be thin and less dense. 

For Ultherapy Knee Treatment, we typically recommend a shallower depth of treatment. Specifically, we can typically provide safe and effective skin tightening treatment with the  1.5 mm or 3.0 mm transducer. To reiterate, the skin on the knees is thinner and more delicate than other body areas, so treatment parameters need to be carefully adjusted to protect this sensitive area while maximizing collagen production.

Ultherapy PRIME takes the proven technology of Ultherapy and makes it faster, more precise and more comfortable. 

Using micro-focused ultrasound with real-time imaging (called Deep-See Technology), your provider can actively visualize where the energy is delivered, ensuring targeting treatment where you need it most.

Key advantages of Ultherapy PRIME:

• One session, no needles, no scars — quick and convenient for busy NYC lifestyles
• Safe for all skin tones — effective for everyone without pigmentation risk
• Improved comfort — pain scores reported at less than half of older devices
• FDA-cleared for face, arms and abdomen

To summarize, Ultherapy PRIME offers results that are more predictable, more comfortable and faster to achieve, while maintaining the unparalleled skin tightening results that has made Ultherapy the go-to non-surgical treatment in Manhattan and across New York City.

Your Ultherapy PRIME knees session usually lasts 30–90 minutes. Here’s what to expect, step by step:

Step 1: Consultation & Mapping

Before treatment, a licensed provider evaluates your knees, assesses skin laxity, crepiness, and overall tone, and maps the areas to be treated. This ensures precise targeting and optimal results.

Step 2: Preparation

Your provider cleans the treatment area. While Ultherapy PRIME is non-invasive, they may apply a topical numbing cream to increase comfort. There are no injections or incisions.

Step 3: Ultrasound Imaging

Your practitioner will use an Ultherapy hand-held device to glide over the surface of the skin. It uses real-time ultrasound to visualize the skin’s layers. This allows the provider to target deep connective tissue without affecting the surface, making the treatment safe for all skin tones.

Step 4: Energy Delivery

Micro-focused ultrasound energy is delivered in a systematic pattern across your arms. You may feel mild tingling, warmth, or pressure, but with Ultherapy PRIME, discomfort is significantly reduced compared to older devices.

Once the session is finished, you can return to your daily activities immediately. 

Clients can expect Ultherapy results for knees including:

• Boosting collagen and elastin production — for firmer, more youthful skin
• Restoring saggy skin / loose skin around knees — addressing aging or post-weight-loss skin
• Improving volume — creating a smoother contour above the knees
• Increasing skin’s elasticity — enhancing flexibility and resilience
• Smoothing wrinkly knee skin — reducing the appearance of knee wrinkles
• Diminishing skin laxity — targeting crepey, loose areas for a toned look
• Improving crepey skin — revitalizing thin, delicate skin above the knees
• Tightening knee skin — non-surgical lift and firming
• Firming knee skin — for a toned, youthful contour

Good candidates for Ultherapy are people:

• With mild to moderate laxity due to aging or weight loss
• Experiencing crepey knee skin or knee wrinkles that just won’t tighten with exercise or superficial fixes like creams
• New Yorkers who want a non-surgical, no-downtime treatment to tighten knee skin

Results typically become noticeable 2-3 months post-treatment and continue to improve up to 6 months as collagen rebuilds. 

Many clients report increased confidence in wearing skirts and shorts again without feeling self-conscious. 

Results are long-lasting, and most clients schedule a maintenance session at around one year to su\tain optimal knee skin tightening and continued firmness.

Many people mistake loose skin around the knees for knee fat. Even if your legs are toned and you’re at a healthy weight, the skin over your knees can appear saggy or “puffy” due to aging, weight loss or genetics. This isn’t always extra fat — it’s often a natural loss of skin elasticity and collagen.

If you do have knee fat, targeted exercise can help tone the muscles beneath, but it won’t tighten the loose skin itself. That’s where Ultherapy PRIME comes in. By stimulating collagen production, it lifts and firms the skin, smoothing wrinkles and sagging areas without surgery.

For the best results, a combination of healthy weight management, leg-strengthening exercises, and nonsurgical skin tightening can address both “knee fat” and loose knee skin, giving your knees a more toned, youthful appearance.

Ultherapy PRIME works to tighten skin regardless of the cause, so yes, Ultherapy is a terrific knee skin tightening treatment following GLP-1 weight loss.

This is a place where the Ultherapy PRIME system shines compared to traditional Ultherapy. The system is designed for improved comfort, with reported pain scores less than half of older devices. 

Most patients describe mild tingling or warmth during the session rather than significant discomfort.

Most patients only require a single treatment to achieve knee skin tightening results. 

Maintenance sessions are often scheduled at the one-year mark, but can be decided in consultation with your provider.

Common side effects are temporary and mild, including redness, swelling, tingling, or minor bruising. These usually resolve within a few hours to a couple of days, allowing you to return to your daily routine immediately.

Compared to surgical knee lifts, the difference is dramatic. Surgery involves incisions, stitches, anesthesia, and significant downtime, often requiring weeks of recovery and leaving visible scars along the inner arm. 

In contrast, Ultherapy PRIME is non-invasive without cuts, scars, or extended recovery. For patients who want natural-looking, subtle results with minimal disruption, Ultherapy is a safer, faster, and low-risk alternative to surgery.

One of the biggest benefits of Ultherapy PRIME is zero downtime. You can return to your normal activities immediately after treatment.

Another great Ultherapy benefit is that it’s a noninvasive alternative to plastic surgery.

In fact, many plastic surgeons advise against a surgical knee lift, because there’s nowhere to hide the scarring that occurs when the skin is cut away. During a neck lift or facelift, scarring can conveniently be hidden behind the ears. That’s clearly not an option on the exposed knee area.

What’s more, Ultherapy downtime, side effects and recovery are typically minimal and easily tolerable, unlike surgery.

Moreover, knee skin tightening surgery can be costly and require weeks of recovery, whereas Ultherapy allows you to return to your normal activities immediately after treatment. For many patients, the trade-off of a gradual natural lift versus invasive surgery with scarring and downtime makes Ultherapy the preferred choice.

Most patients tolerate the procedure well, with only mild and temporary discomfort.
