Ultherapy Body Treatment For Skin Laxity on Arms, Stomach, Butt, Thighs, Knees | Nonsurgical Ultherapy Skin Tightening NYC
When we hear the words “body contouring without surgery”, we tend to think about fat removal or getting rid of cellulite.
However, certain complaints about the body have nothing to do with how much fat we carry. We’re talking specifically about loose, wrinkly and saggy skin that happens as we age.
That’s where Ultherapy Body Contouring holds a distinct advantage. It’s highly effective for skin tightening on the stomach, butt, arms, thighs or knees, regardless of your weight.
What’s more, Merz Aesthetics, the makers of Ultherapy, have just announced a major technological upgrade. Called Ultherapy PRIME, this system is faster, more precise, and significantly more comfortable than traditional Ultherapy. And it’s now FDA-cleared for use on the arms and abdomen.
The result is deeper, more effective lifting, improved skin tone, and less discomfort — all without surgery, needles, or downtime.
Put simply, Ultherapy PRIME isn’t just another skin-tightening treatment — it’s the latest innovation in non-invasive body contouring.
Here’s why Ultherapy Body Treatment might be the body contouring solution you’re looking for, courtesy of the best Med Spa in NYC:
What is Ultherapy? How Does Ultherapy Work?
Put simply, Ultherapy encourages Collagen and Elastin production, which provide support for the skin.
Specifically, a criss-cross network of collagen sits at the dermis level of the skin. This scaffold anchors the skin and provides it with a sturdy structure.
Collagen works in tandem with Elastin. Specifically, Elastin is a protein in the connective tissue that assures our skin’s elasticity — that’s how quickly it bounces back to its original shape after stretching or contracting.
Ultherapy works to heat the skin at the dermis level of the skin and spark neocollagenesis and elastin remodeling. This has particular benefit, if you’re looking for skin tightening on the body due to:
- Weight loss,
- Childbirth,
- The natural course of aging.

Ultherapy Body: Why Does Ultherapy Body Contouring Work for the Body?
In general, Ultherapy is the gold standard for skin tightening. In fact, it’s the only FDA-cleared, noninvasive procedure specifically indicated for skin tightening on the face and has just gained FDA-clearance for use on the stomach and arms.
Currently, Ultherapy body treatment is off-label treatment for knees, buttocks and thighs. However, Merz, the makers of Ultherapy, are in the process of designing studies to prepare for FDA consideration of all Ultherapy body treatments.
Specifically, Ultherapy is the most targeted non-invasive treatment for skin tightening. It uses safe, time-tested ultrasound to bypass the surface of the skin, depositing tiny amounts of energy to clearly-defined depths under the skin. Three transducer allow the practitioner to target the depth of treatment to 1.5 mm, 3.0 mm and 4.5 mm beneath the skin. This works to improve:
- Saggy skin
- Wrinkly skin
- Skin laxity
- Crepey skin
What Is Ultherapy PRIME? Can Ultherapy be Done on Arms, Stomach and More?
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 for arms:
- 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 arms and abdomen — the only device officially cleared to lift and tone upper arms
To summarize, Ultherapy PRIME offers results that are more predictable, more comfortable, and faster to achieve, while maintaining the unparalleled skin tightening results for the body that has made Ultherapy the go-to non-surgical treatment in Manhattan and across New York City.
What Areas of the Body Can Be Treated with Ultherapy?
Ultherapy is best known for lifting and tightening skin on the face and neck — but its benefits extend far beyond that. Thanks to its customizable ultrasound technology and variable treatment depths (1.5 mm, 3.0 mm, and 4.5 mm), Ultherapy can be precisely calibrated to treat nearly any area where skin laxity is a concern.
Here’s a breakdown of the most common Ultherapy treatment areas:
-
Face: Jowls, chin, cheeks, and full face for a non-surgical facelift effect.
-
Brow: A subtle lift to open the eyes and smooth frown lines.
-
Neck: Lifts sagging skin and improves “turkey neck” or banding.
-
Décolletage: Targets crepey or wrinkled skin on the chest.
-
Under-Eyes: Smooths bags and firms delicate skin beneath the eyes.
-
Stomach: Firms loose or crepey skin post-weight loss, aging, or pregnancy.
-
Thighs: Targets sagging inner or outer thighs that don’t respond to workouts.
-
Knees: Tightens thin, loose skin that can’t be treated with fat reduction alone.
-
Buttocks: Provides subtle lift and improves texture for a smoother, toned appearance.
-
Upper Arms: Helps reduce “bat wing” sagging and improves overall skin firmness.
Ultherapy is especially effective in areas that are difficult to treat with other technologies due to delicate structures or variable fat-to-muscle ratios. It’s a versatile, all-in-one solution for noninvasive lifting, smoothing, and skin tightening—without the need for surgery or downtime.
Why is Ultherapy Body Contouring a Good Treatment for Skin Laxity and Skin Texture?
The superior level of control offers a distinct advantage for discrete areas of the body.
Specifically, each body area varies in terms of its composition of fat and muscle (think knee area vs. buttocks, for example).
Further, each patient has their own individual ratio of fat to muscle. Ultherapy offers multiple, targeted options in terms of the depth and density of treatment — going beyond a one-size-fits all approach to skin tightening on the body. To illustrate further:
Ultherapy Arms Treatment / Upper Arms
Treatment depth is customized based on the thickness of the skin and underlying tissue. For most patients, a combination of 1.5 mm and 3.0 mm transducers is used to precisely target sagging or crepey skin, ensuring natural-looking firmness and tone.
Ultherapy Knee Treatment / Around the Knees
Generally, requires a shallower depth of treatment, either 1.5 mm or 3.0 mm transducer, because the skin on the knees is thin and less dense.
Ultherapy Buttocks Treatment / Butt Area
The butt requires an examination to assess whether connective tissue is no more than 4.5 mm under the skin.
Ultherapy Thigh Treatment / Inner and/or Outer Thighs
Sometimes requires use of all three transducers, in order to achieve best results. This is because the depth of skin on the thighs can vary.
Ultherapy Stomach Treatment / Abdominal Area
Treatment depth depends on skin thickness and tissue laxity, typically using 3.0 mm and 4.5 mm transducers, depending on the patient.
Please note: these are general recommendations and a skilled practitioner will always use real-time feedback from the monitor (Ultherapy’s proprietary DeeSee technology) to guide the treatment.
How Does Ultherapy Compare to Other Body Contouring Treatments?
Unlike treatments that focus primarily on fat reduction, such as CoolSculpting or radiofrequency lipolysis, Ultherapy specifically targets skin laxity by stimulating collagen deep within the skin layers. This makes it uniquely effective for patients whose main concern is loose, sagging skin rather than excess fat.
While liposuction or surgical lifts provide results, Ultherapy offers a noninvasive alternative with minimal downtime, making it ideal for those seeking gradual, natural-looking skin tightening.
What to Expect During and After Ultherapy Body Treatment? What Results to Expect?
Ultherapy sessions typically last between 45 to 90 minutes depending on the treatment area. You may feel mild discomfort as ultrasound energy is delivered beneath the skin, but topical numbing can be applied to ease this.
Post-treatment, some patients experience slight redness, swelling, or tingling that usually resolves within a few days. Since Ultherapy works by triggering your body’s collagen renewal, visible improvements in skin tightness appear gradually over 2 to 3 months, with results lasting up to a year or more.
Who’s an Ideal Candidate for Ultherapy Body Contouring?
Ultherapy is best suited for individuals experiencing mild to moderate skin laxity, who are looking for a non-surgical option to lift and firm the skin.
Can You Combine Ultherapy with Other Treatments?
For enhanced body contouring results, Ultherapy can be combined with RF Microneedling or Endermologie to improve overall skin texture. Discuss with your provider a customized plan tailored to your body goals.
