Fat Dissolving Injections: What Body Areas Can Be Targeted?

 

If you’ve been eating well, exercising regularly, and still dealing with pockets of stubborn fat, you’re not alone. Some fat just won’t budge—no matter how hard you try. That’s where fat dissolving injections come in.

Also known as injectable lipolysis, these treatments offer a non-surgical alternative to liposuction. They’re designed to target and break down fat in localized areas, helping you contour and sculpt your body with precision.

But here’s the big question: What body areas can be treated with fat dissolving injections? In this guide, we’ll break it all down. You’ll discover which zones respond best, how the treatment works, what results you can expect, and whether it’s the right option for you.

 

What Are Fat Dissolving Injections?

 

Before diving into the body areas, it’s helpful to understand the basics.

Fat dissolving injections are made with compounds like deoxycholic acid, a naturally occurring bile acid in the body that helps absorb fat. When injected into fatty tissue, these substances destroy fat cells, which your body then flushes out through the lymphatic system over the course of several weeks.

Common Fat-Dissolving Brands:

• Kybella (U.S. brand) – FDA-approved for submental fat (double chin)
• Aqualyx – Popular in Europe and other international markets
• DesoFace and DesoBody – Designed specifically for facial or body areas

Once the fat cells are gone, they’re gone for good—as long as you maintain a stable weight.

 

1. Double Chin (Submental Fat)

 

Let’s start with the most well-known area: the double chin.

Excess fat under the chin can be genetic or related to weight gain, and it’s notoriously tough to eliminate with diet and exercise alone.

Why it works:

• The submental area is relatively small and contained.
• Kybella is FDA-approved specifically for this purpose.
• Results are typically visible after 2 to 4 sessions.

 

2. Jowls and Lower Face

 

Yes, fat dissolving injections can help sculpt your face, not just your body.

Areas commonly treated:

• Jowls
• Jawline definition
• Lower cheeks (in some cases)

These micro-contouring injections can create a snatched look, especially when paired with skin-tightening treatments like RF or ultrasound.

Caution: Because the facial area has thinner skin and complex anatomy, this treatment should only be done by an experienced medical professional.

 

3. Bra Bulge and Upper Back

 

That pesky roll of fat where your bra strap digs in? It’s a perfect target.

The upper back and bra bulge area responds well to fat-dissolving injections, especially in women who are otherwise fit but genetically predisposed to storing fat in this zone.

Benefits:

• Non-surgical smoothing of back fat
• More flattering fit for clothes and undergarments
• Sessions take less than 30 minutes

 

4. Abdomen (Lower Belly Fat)

 

Your lower belly is another common area for localized fat retention.

Fat dissolving injections can be used to fine-tune the area for people who are at or near their ideal weight but want more definition.

Important note:
This treatment is not a weight loss solution—it’s a body sculpting treatment for small pockets of fat.

You’re a good candidate if:

• You have pinchable belly fat
• You’re already within 10-15 lbs of your goal weight
• You’re looking for non-surgical contouring

 

5. Love Handles (Flanks)

 

Love handles can linger even with regular cardio and clean eating.

Fat dissolving injections in the flanks help contour the waist, giving you a smoother silhouette—ideal if you’re aiming for that hourglass figure or a leaner V-tapered look.

 

6. Inner and Outer Thighs

 

Thigh fat is a common concern, especially for women. You can treat:

• Inner thighs – for a more comfortable thigh gap
• Outer thighs – to reduce “saddlebag” bulges

Results can be gradual but impressive over a series of sessions.

Quick tip: This area often responds better when combined with treatments like radiofrequency (RF) microneedling for skin tightening.

 

7. Knees

 

Surprised? Knees are often overlooked—but they can hold on to fat that ruins the line of fitted jeans or skirts.

Fat dissolving injections can smooth the fat above or to the sides of the knees, creating a sleeker leg shape overall.

 

8. Upper Arms (Bingo Wings)

 

Fat under the arms—sometimes called “bat wings” or “bingo wings”—is notoriously difficult to tone.

Fat dissolving injections can help reduce arm circumference for people with mild to moderate fat in the area. For better results, they’re often paired with skin-tightening or muscle-stimulating treatments.

 

9. Banana Roll (Under Buttocks)

 

This small area of fat under the butt can affect how clothing fits and make the buttocks look less defined.

Injections here help lift and smooth the gluteal crease, enhancing the overall shape of the backside.

 

10. Ankles and Calves

 

For those genetically predisposed to “cankles”—a blend of calf and ankle with no visible taper—fat dissolving injections can subtly contour and define the area.

Important: These treatments should be approached cautiously and performed only by highly trained specialists due to the complexity of lymphatic drainage in the legs.

 

11. Male Chest (Pseudogynecomastia)

 

In men, excess fat in the chest can mimic gynecomastia (enlarged male breast tissue).

For cases caused by fat, fat-dissolving injections can flatten and firm the appearance of the male chest without surgery.

 

12. Mons Pubis

 

The mons pubis, the fatty tissue above the pubic bone, can be a source of self-consciousness—especially in tight clothing or swimsuits.

Injectable lipolysis in this area is increasingly popular and can be done discreetly in medical aesthetic clinics.

 

How Many Sessions Will You Need?

 

Most areas require 2 to 6 sessions, spaced about 3–6 weeks apart. The exact number depends on:

• The treatment area
• Your body’s response
• The amount of fat present
• Desired results

Your provider will tailor a plan specifically for you during a consultation.

 

Are the Results Permanent?

 

Yes—fat cells removed by injection don’t come back. However, this doesn’t mean you’re immune to weight gain. If you gain weight after treatment, remaining fat cells in the body can still expand.

Maintain your results by:

• Eating a balanced diet
• Staying active
• Keeping your weight stable

 

Are There Side Effects?

 

Most side effects are mild and temporary, such as:

• Swelling
• Bruising
• Redness
• Tenderness
• A mild burning sensation

Rare but serious complications can occur if the product is injected incorrectly, which is why choosing a skilled professional is essential.

 

Who Should Avoid Fat Dissolving Injections?

 

You may not be a good candidate if you:

• Are pregnant or breastfeeding
• Have loose or sagging skin (treatment targets fat, not laxity)
• Have active infections or skin conditions in the treatment area
• Are significantly overweight (this is not a substitute for weight loss)

Always consult with a licensed medical provider before starting treatment.
