Introduction

Fat-dissolving injections have quickly gained popularity as a non-invasive method for body contouring. These injections target localized fat, breaking it down to help reduce stubborn areas of fat. While many people see great results in terms of fat reduction and a more toned appearance, there are concerns about whether these treatments could lead to sagging skin.

The short answer is, yes, fat-dissolving injections can, in some cases, lead to sagging. However, this outcome isn't inevitable, and there are several factors to consider before and after treatment. Let’s dive deeper into how fat-dissolving injections work and why sagging might occur—and, more importantly, how to avoid it.

How Fat-Dissolving Injections Work

Fat-dissolving injections typically contain substances like deoxycholic acid, which is a naturally occurring bile acid that helps break down fat cells. Once injected into the target area, it disrupts the fat cells, which are then processed by the body’s natural systems. Over time, this leads to a noticeable reduction in fat in the treated area.

The most well-known fat-dissolving treatment is Kybella (the brand name for deoxycholic acid), but there are other alternatives available as well. Fat-dissolving injections are used on areas like the chin (to treat a double chin), abdomen, thighs, or under the arms.

Can Fat-Dissolving Injections Cause Sagging?

It’s a common question, and the concern is rooted in the idea that when fat is removed from an area, the skin might be left hanging loosely, especially if the skin has lost some of its natural elasticity. This is particularly a concern for areas of the body where the skin is thinner or has already experienced some loss of firmness due to age or other factors.

Here are a few key reasons why sagging might occur:

1. Speed of Fat Loss

Fat-dissolving injections lead to a gradual reduction in fat, but this doesn’t always mean the skin will keep pace with the changes. If fat is removed too quickly, and the skin is not able to tighten up in response, sagging can result. For instance, in areas like the stomach or inner thighs, where skin is already prone to laxity, the removal of fat could create a flabby appearance. In cases where fat is eliminated too aggressively or all at once, the skin’s ability to “bounce back” could be compromised, leading to sagging.

2. Lack of Skin Elasticity

The condition of your skin plays a big role. Younger skin tends to be more elastic and better able to bounce back after fat reduction treatments. On the other hand, older skin, or skin that has been exposed to sun damage or other environmental factors, may not respond as well. This can lead to a looser, sagging appearance after fat reduction. For example, skin around the abdomen and thighs is often more prone to sagging, especially after significant weight loss or fat reduction.

The elasticity of the skin depends on collagen and elastin, which naturally decrease with age or prolonged sun exposure. This can make it harder for the skin to contract and firm up after fat loss. For individuals with skin that is already starting to lose some firmness, extra precautions may be needed when considering fat-dissolving injections.

3. Treatment Areas

Certain areas of the body are more prone to sagging than others. For example, the neck or jawline might experience some mild sagging if there is a significant amount of fat reduction, especially if the skin in that area has already started to lose elasticity. The risk is lower in areas with thicker skin or more muscle tone underneath, like the abdomen or thighs.

Fat-dissolving treatments around the chin and jawline—while effective in reducing the appearance of a double chin—can sometimes lead to sagging if the skin is not able to bounce back after the fat is dissolved. The skin around the neck is often more delicate and less elastic than other areas, so extra care must be taken when treating this zone.

How to Minimize the Risk of Sagging

While some degree of sagging is possible, there are steps you can take to reduce the likelihood and improve your outcomes:

1. Combine with Skin Tightening Treatments

One of the most effective ways to avoid sagging after fat-dissolving injections is to combine the injections with skin tightening treatments. Procedures like radiofrequency therapy or laser skin rejuvenation can help stimulate collagen production, tightening the skin and helping it contract more effectively. At PlanS Clinic, we often recommend pairing fat-dissolving injections with treatments like Ultherapy, which uses focused ultrasound to stimulate deep layers of the skin, promoting collagen production and helping the skin tighten after fat reduction.

Radiofrequency treatments work by delivering energy to the skin's deeper layers, encouraging the production of collagen and elastin. This not only helps tighten the skin but also improves its texture and firmness. When combined with fat-dissolving injections, these treatments can provide more balanced results, avoiding the risk of loose skin.

2. Gradual Fat Reduction

To prevent the skin from stretching or becoming too loose, it’s important to be patient with fat-dissolving injections. Opting for smaller, more gradual treatments can help the skin adjust and maintain its firmness. Rather than removing all the fat at once, we suggest a more cautious approach that allows for better skin adaptation. When performed in stages, the fat is reduced in a way that gives the skin enough time to tighten naturally.

Taking a conservative approach can also help you assess how your skin responds to the treatment, making it easier to monitor progress and make adjustments if necessary. This gradual approach is often more beneficial in preventing sagging, especially for areas like the neck, underarms, and stomach.

3. Maintain Healthy Skin

Keeping your skin healthy and well-hydrated before and after treatment can enhance its elasticity. Using products with collagen-stimulating ingredients, such as retinoids or hyaluronic acid, can improve skin texture and tightness. Drinking plenty of water, maintaining a balanced diet, and avoiding smoking and excessive sun exposure can all contribute to better skin health and elasticity.

Topical treatments that encourage skin regeneration, such as peptides or growth factors, can also help improve the overall condition of your skin. These products can boost the skin's ability to recover from the fat-dissolving process, supporting smoother and firmer skin after treatment.

4. Post-Treatment Care

After fat-dissolving injections, follow your doctor’s aftercare instructions carefully. This may include wearing compression garments in the treated areas (if recommended), which can help the skin contract and reduce the risk of sagging. Staying active with regular exercise can also help improve overall skin tone. Exercise stimulates blood circulation, promoting healthy skin and helping it adapt to the changes occurring beneath the surface.

Additionally, it’s important to avoid strenuous activity for the first few days after treatment to minimize swelling and inflammation. Over time, as the fat breaks down, your skin will gradually adjust, but patience and proper care are essential for optimal results.

Is Fat Dissolving Right for You?

If you’re considering fat-dissolving injections but are concerned about the possibility of sagging, it’s important to have a thorough consultation with an experienced specialist. At PlanS Clinic, our expert team, led by Dr. Do Geon Gi, will assess your individual skin type, treatment area, and goals to develop a tailored treatment plan that minimizes risks like sagging.

We understand that every patient is unique, and we prioritize delivering results that are not only effective but also look natural and smooth. Fat-dissolving injections may be ideal for certain individuals seeking to target small, stubborn areas of fat. However, for others with concerns about skin laxity or areas with more significant fat deposits, we may recommend alternative treatments like liposuction or body contouring procedures in combination with non-invasive therapies.

Our approach is always centered around your long-term satisfaction and well-being, ensuring that any treatment we recommend is the best fit for your needs.

Conclusion

Fat-dissolving injections can cause sagging in some cases, particularly if there’s a significant amount of fat removal or if the skin lacks elasticity. However, with proper care, gradual treatments, and possibly combining with skin-tightening therapies, the risk of sagging can be minimized.
