Managing Belkyra® Swelling: Duration & Care Guide

Belkyra®—known as Kybella® in the U.S.—is a Health Canada–approved injectable used to reduce submental fat (commonly known as a double chin). It’s a non-surgical way to contour the jawline, and a popular alternative to liposuction among clients at Celebrity Laser & Skin Care in North Vancouver.

While the treatment is highly effective, it does come with temporary side effects—swelling being the most common. Knowing what to expect and how to manage it can make your recovery smoother and less stressful.

In this guide, you’ll find a clear swelling timeline, practical aftercare tips, and expert insights based on real clinical experience.

What is Belkyra® and how does it work?

Belkyra® is an injectable treatment that uses synthetic deoxycholic acid, a molecule naturally produced by the body to help break down dietary fat. When injected into the fat beneath the chin (submental area), it destroys targeted fat cells through a process called adipocytolysis.

Once the fat cells are broken down, they’re gradually cleared away by the body’s lymphatic system. Because these cells don’t regenerate, the results can be long-lasting.

Treatments typically take 15 to 30 minutes and require no anesthesia. Most clients receive a series of sessions spaced about four weeks apart, with minimal recovery time in between.

While mild swelling and redness are common after each appointment, these effects usually subside within a couple of days.

Why does swelling happen after Belkyra®?

Swelling is a normal, expected part of Belkyra® treatment—and actually signals that the fat breakdown process is working. There are three key reasons why swelling occurs:

1. Inflammatory Response to Fat Cell Breakdown

As Belkyra® destroys fat cells, the body triggers an inflammatory response to begin the healing and clearing process. This immune activity naturally causes swelling, redness, and tenderness.

2. Injection-Related Tissue Trauma

The act of injecting the product into the submental area causes minor trauma to surrounding tissues. This results in additional fluid buildup, especially in the first 24–48 hours.

3. Slower Lymphatic Drainage in the Neck

The chin and neck area drain fluid more slowly than other parts of the body. This can make swelling feel more pronounced or persistent, especially after the first treatment.

While the swelling can be noticeable, it’s temporary—and an essential step in achieving permanent fat reduction.

How long does swelling from Belkyra® last?

Swelling after Belkyra® treatment is temporary—but how long it lasts depends on several factors.

Most clients experience visible swelling for 3 to 7 days.

In some cases, especially after the first session, mild puffiness can linger for up to 10 days. This is completely normal and part of the body’s fat elimination and healing process.

Factors that influence swelling duration include:

1. First vs. Follow-Up Sessions

The initial treatment usually triggers the most noticeable swelling. With each subsequent session, there are fewer fat cells to target, so the inflammatory response tends to be milder and resolves more quickly.

2. Dosage and Volume Injected

Higher volumes of Belkyra® result in greater fat breakdown, which can increase swelling. Your provider will adjust the dosage to suit your facial structure and goals.

3. Individual Healing Response

Age, metabolism, immune health, and hydration all play a role in how fast your body clears the treated fat and recovers from inflammation.

4. Medical Conditions and Medications

If you have thyroid imbalances, circulatory issues, or take blood-thinners, you may notice swelling lasts longer or resolves more gradually.

What to Discuss with Your Doctor Before Belkyra® Treatment

Before undergoing Belkyra® at Celebrity Laser & Skin Care, you’ll first have a personalized consultation to assess your treatment goals, medical background, and overall candidacy.

Be prepared to discuss the following with your provider:

• Previous facial procedures: Let your provider know if you’ve had any surgeries or cosmetic treatments on or around the chin, neck, or jawline.
• Medical conditions in the neck area: Swallowing difficulties, thyroid issues, or chronic neck pain may influence your treatment plan.
• Bleeding disorders or medications: If you’re on blood thinners or supplements that affect clotting, your provider may adjust your protocol or recommend timing strategies.
• Pregnancy or breastfeeding: Belkyra® has not been tested for safety during pregnancy or lactation, so treatment is typically postponed.

Current skincare or injection plans: If you’ve recently had fillers or plan to do so soon, coordination is important to avoid interactions or swelling overlap.

This conversation ensures your safety while helping us tailor your Belkyra® session for optimal results—with the right dose, spacing, and aftercare from the start.

How to Manage Swelling After Belkyra®

Swelling is a normal part of the healing process—but the way you manage it can make a big difference in how quickly you feel (and look) back to normal. With a few simple at-home strategies and a solid aftercare plan, you can minimize discomfort and support smoother recovery.

Use a Cold Compress

Apply a cold pack wrapped in a soft cloth to the area for 10–15 minutes at a time. Avoid direct ice contact and always take short breaks between sessions. This helps reduce inflammation and soothes tenderness in the first 24–48 hours.

Sleep with Your Head Elevated

Use an extra pillow or sleep on a recliner for the first few nights. Elevation encourages lymphatic drainage and helps reduce fluid buildup under the chin.

Avoid Alcohol and Salty Foods

Both can increase water retention and swelling. Stick to hydrating fluids and nutrient-rich meals in the days after treatment to support healing.

Limit Physical Activity

Skip heavy workouts, hot yoga, or anything that raises your body temperature for 48 hours. Gentle walks are fine, but overexertion may worsen swelling or bruising.

Don’t Massage the Treated Area

It might feel tempting, but massaging can disturb the treatment area and delay healing. Leave it alone—Belkyra® works best when the area is left undisturbed.

Follow Your Clinic’s Aftercare Plan

Each person’s response is different. At Celebrity Laser & Skin Care, your aftercare will be customized to your anatomy, treatment volume, and recovery speed. Follow the instructions provided, and don’t skip your follow-ups—they’re part of your success.

➤ Planning Tip: If you have social or professional events coming up, consider scheduling your treatment at least a week in advance to allow swelling to subside.

What to Watch Out For

While mild swelling, tenderness, and bruising are expected after Belkyra®, certain symptoms may indicate a need for medical evaluation.

Here’s when to contact your provider:

• Severe or asymmetric swelling: Especially if one side becomes significantly more swollen than the other.
• Signs of infection: Look for increased warmth, redness, pus, or fever.
• Difficulty swallowing or breathing: These are rare but serious side effects that require immediate attention.
• Persistent or worsening pain: If pain intensifies or does not improve over several days, it’s worth following up.
• Hardened lumps or nodules: While some firmness is common during healing, persistent or painful lumps should be assessed.

These reactions are uncommon, especially under experienced care. At Celebrity Laser & Skin Care, all Belkyra® treatments are performed by trained professionals who monitor for any signs of complications and provide clear aftercare guidance.

Long-Term Outlook

One of Belkyra®’s biggest advantages is its long-lasting effect. Once the targeted fat cells are destroyed, they do not regenerate—making the results semi-permanent to permanent for most patients.

Here’s what you can expect long-term:

• Visible contouring improvements usually appear after the second or third session, once swelling subsides and your lymphatic system clears the treated fat.
• Retreatment is rarely needed, especially if you maintain a stable weight and healthy lifestyle. While Belkyra® doesn’t prevent future fat accumulation, most patients enjoy long-term results.
• Weight gain can impact outcomes: If you gain a significant amount of weight, remaining fat cells in the area can expand, slightly diminishing the definition achieved.

At Celebrity Laser & Skin Care, we provide customized maintenance plans when needed and assess your results after each session to ensure you stay on track with your aesthetic goals.

Final Thoughts on Swelling and Recovery After Belkyra®

Swelling after Belkyra® isn’t a complication—it’s a natural part of how the treatment works. As the fat breaks down, your body responds with inflammation, which then clears as healing progresses.

While the swelling is most noticeable in the first 3 to 7 days, recovery typically feels manageable, especially with proper post-care.
