If you’ve started noticing loose skin along your jawline, neck, or other areas of your body, you’re not alone. As we age, our skin naturally loses collagen and elastin—the proteins that keep it firm, smooth, and youthful. Significant weight loss, sun exposure, and genetics can also contribute to skin laxity, leaving many people looking for effective solutions that don’t involve surgery.

Fortunately, advances in cosmetic technology have made it possible to tighten and rejuvenate the skin without incisions or lengthy recovery times. One of the newest options available is XERF Skin Tightening, an innovative treatment that stimulates your body’s natural collagen production to improve skin firmness and elasticity.

At Skin Cancer & Cosmetic Surgery Center of New Jersey, we offer XERF to help patients achieve natural-looking results with minimal downtime. Whether you’re concerned about early signs of aging or loose skin after weight loss, this treatment may be an excellent option.

What Is XERF Skin Tightening?

XERF Skin Tightening is a non-surgical treatment that uses advanced radiofrequency (RF) technology to gently heat the deeper layers of the skin. This controlled heating stimulates collagen remodeling while encouraging your body to produce new collagen and elastin over time.

Rather than simply treating the surface of the skin, XERF works beneath the surface where structural changes occur. As new collagen develops, the skin gradually becomes firmer, smoother, and more youthful in appearance.

Unlike surgery, there are no incisions, stitches, or extensive recovery periods, making XERF an attractive option for patients looking for noticeable improvement with little interruption to their daily routine.

Why Does Skin Become Loose?

Many people associate loose skin with aging, but several factors contribute to skin laxity.

Beginning in our mid-to-late twenties, collagen production naturally declines each year. As collagen decreases, the skin loses its ability to bounce back, leading to:

• Sagging around the jawline
• Loose skin on the neck
• Fine lines and wrinkles
• Crepey skin texture
• Reduced elasticity
• Less defined facial contours

Weight fluctuations can also stretch the skin. While losing weight is an incredible achievement, especially after lifestyle changes or GLP-1 medications, many patients find that excess skin remains long after they’ve reached their goal weight.

Unfortunately, no amount of exercise can tighten loose skin once collagen has been lost. That’s where collagen-stimulating treatments like XERF can make a meaningful difference.

How Does XERF Work?

Radiofrequency technology has been used safely in aesthetic medicine for years because of its ability to stimulate collagen production without damaging the surface of the skin.

During a XERF treatment, controlled radiofrequency energy heats the deeper layers of tissue to an optimal temperature that encourages collagen remodeling.

This process produces two important effects:

First, existing collagen fibers contract, creating an initial tightening effect.

Second, the body begins producing new collagen over the following weeks and months. Because collagen develops gradually, improvements continue long after the treatment has been completed.

The result is firmer, smoother, healthier-looking skin that continues to improve naturally over time.

What Areas Can Be Treated?

One of the biggest advantages of XERF is its versatility. It can be used on both the face and body to improve skin laxity in multiple areas.

Common treatment areas include:

Face

• Jawline
• Lower face
• Cheeks
• Smile lines
• Marionette lines

Neck

The neck is often one of the first places to show signs of aging. XERF can help improve loose neck skin while enhancing jawline definition.

Abdomen

Many patients choose XERF after pregnancy or weight loss to improve mild skin laxity around the abdomen.

Arms

Loose upper arm skin can be difficult to improve with exercise alone. XERF helps stimulate collagen to improve firmness.

Thighs

Inner thigh skin often loses elasticity with age and weight changes. XERF can improve skin quality and firmness in this area.

Bra Line, Flanks, Knees, and Other Body Areas

Patients can also address mild laxity in additional body areas that commonly develop loose or crepey skin over time.

Who Is a Good Candidate for XERF?

XERF is an excellent treatment for patients who want to improve mild to moderate skin laxity without surgery.

You may be a good candidate if you:

• Have noticed loose skin around your jawline or neck.
• Have mild sagging following weight loss.
• Want firmer skin without undergoing surgery.
• Are beginning to see signs of aging.
• Want natural-looking improvement rather than dramatic changes.
• Prefer little to no downtime.

The best candidates are generally healthy individuals with realistic expectations who are looking to improve skin quality and firmness.

During your consultation, your provider will determine whether XERF is the most appropriate treatment based on your goals and skin condition.

XERF After Weight Loss

One of the fastest-growing groups seeking skin tightening treatments includes patients who have experienced significant weight loss.

Whether you’ve lost weight through diet and exercise or with the help of GLP-1 medications, loose skin can sometimes prevent you from fully enjoying your results.

Weight loss reduces fat volume, but it cannot restore collagen that has already been stretched or depleted.

XERF helps address this concern by stimulating collagen production, improving skin firmness, and enhancing body contours.

Many patients choose to begin skin tightening treatments after reaching or getting close to their goal weight to maximize their results.

What Is Treatment Like?

Most appointments take between 30 and 60 minutes depending on the treatment area.

During the procedure, you’ll feel warmth as radiofrequency energy is delivered beneath the skin. Most patients tolerate the treatment very well and find it comfortable.

Once your appointment is complete, you can typically return to your normal daily activities.

Unlike surgical procedures, there are no stitches, bandages, or lengthy recovery periods.

Is There Downtime?

One of the reasons patients love XERF is its minimal downtime.

Some patients experience temporary redness or mild warmth immediately following treatment, but these effects generally resolve quickly.

Most people return to work, social activities, or their normal routine the same day.

When Will I See Results?

Because XERF stimulates your body’s natural collagen production, results develop gradually.

Some patients notice early improvements in skin firmness, while continued collagen remodeling occurs over the following several months.

This gradual process creates natural-looking improvement rather than an overly dramatic or artificial appearance.

How Many Treatments Will I Need?

Every patient is different.

Your treatment plan will depend on factors such as:

• Your age
• Skin quality
• Degree of laxity
• Treatment area
• Cosmetic goals

During your consultation, we’ll recommend a customized treatment plan designed specifically for your needs.

Can XERF Be Combined With Other Cosmetic Treatments?

Absolutely.

Many patients achieve even better results by combining skin tightening with other cosmetic procedures.

Depending on your goals, your provider may recommend combining XERF with treatments that improve facial wrinkles, restore lost volume, enhance skin texture, or address sun damage and pigmentation.

A personalized treatment plan allows multiple concerns to be addressed while maintaining natural-looking results.
