What Are BNLS Injections? Ingredients and Features Explained

BNLS injections are used for facial slimming and contouring treatments. Plant-derived ingredients are injected directly into areas of concern to promote fat dissolution.
Because they can help reduce fat in targeted areas without surgery, BNLS injections are a frequently chosen body contouring treatment for facial spot reduction.
The main ingredient in conventional fat-dissolving injections was a compound called “phosphatidylcholine,” which carried a relatively higher risk of side effects such as swelling and a sensation of heat at the injection site. In contrast, the primary ingredient in BNLS—”deoxycholic acid”—is plant-derived and is associated with a lower risk of such side effects.
In addition, BNLS injections tend to produce noticeable results relatively quickly, with many patients reporting visible slimming effects within approximately 3 days to 1 week after treatment.
Can They Slim Your Face? 3 Potential Effects of BNLS Injections

When BNLS injections are applied to specific areas of the face, the following three effects may primarily be expected.
- A more defined nose
- Improved appearance of heavy eyelids
- A slimmer-looking face
BNLS injections work through actions such as fat breakdown and skin tightening, helping to reduce fat in targeted areas of concern. Read on for a detailed explanation of each of these potential effects.
① A More Defined Nose
BNLS injections may help create a more refined and defined nose.
A key feature of this treatment is the ability to reduce unwanted fat around the nose without incisions, allowing for nose refinement without leaving visible scarring.
This treatment may be a suitable option for those who wish to define the nasal bridge or who are bothered by a rounded nose tip.
② Improved Appearance of Heavy Eyelids
Administering BNLS injections to heavy eyelids may help reduce puffiness and give the eyelids a lighter, more refreshed appearance.
However, BNLS injections can only address heavy eyelids in cases where the puffiness is caused by subcutaneous fat.
Conditions such as “ptosis” (drooping eyelids caused by weakened muscle function) require a different approach.
Since it can be difficult to determine on your own whether BNLS injections are appropriate for your eyelid concerns, we encourage anyone troubled by heavy eyelids to come in for a consultation first.
③ A Slimmer-Looking Face
Injections into the jaw and cheeks may help work toward a slimmer facial appearance.
The active ingredients help improve blood circulation and lymphatic flow, promoting the elimination of waste products and fat that have accumulated from the jaw to the cheeks. This may result in a more defined facial contour, and could help improve the appearance of a double chin or facial sagging.
In addition, BNLS injections are less likely to cause noticeable post-treatment swelling, reducing the chance that others will notice you have had a procedure.
For those who wish to address a double chin or are bothered by a fuller facial contour, BNLS injections may be worth considering as one option.
Differences Between “BNLS neo” and “BNLS Ultimate”

BNLS injections are primarily available in two formulations—”BNLS neo” and “BNLS Ultimate”—with the key differences outlined below.
| BNLS neo | BNLS Ultimate | |
|---|---|---|
| Primary Active Ingredient | Deoxycholic acid | Deoxycholic acid |
| Additional Ingredients | None | Carnitine Artichoke Catechin Coenzyme Q10 |
| Amount of Deoxycholic Acid | Standard amount | Approx. 20× that of BNLS neo |
| Fat Reduction Effect | May be expected | Greater effect may be expected |
| Cost | Lower | Higher |
Below we provide a detailed overview of the characteristics of each formulation.
① BNLS neo | Contains Deoxycholic Acid for Fat Dissolution
BNLS neo is a fat-dissolving injection that contains deoxycholic acid, an ingredient known to help dissolve fat. Deoxycholic acid works by directly disrupting the cell membranes of fat cells and helping to remove triglycerides (neutral fats).
It also promotes lymphatic circulation and skin tightening, helping to flush out accumulated waste products and dissolved fat from the body.
② BNLS Ultimate | Multiple Additional Active Ingredients Added to BNLS neo
BNLS Ultimate is a fat-dissolving injection that contains all the ingredients found in BNLS neo, along with several additional active ingredients.
It includes “artichoke,” which helps promote the elimination of waste products, as well as “Coenzyme Q10” and “catechin,” which may support skin regeneration and help slow signs of aging. In addition, the concentration of deoxycholic acid is approximately 20 times greater than that in BNLS neo.
While BNLS Ultimate is generally priced higher than BNLS neo, it may offer a greater degree of fat-dissolving effect.
3 Benefits of BNLS Injections

The three main benefits of BNLS injections are as follows.
- Effects may be noticed shortly after treatment
- Targeted fat reduction is possible
- Minimal discomfort and short downtime
Read on for a detailed explanation of each benefit.
① Effects May Be Noticed Shortly After Treatment
A notable feature of BNLS injections is that results tend to become apparent relatively quickly after treatment. While conventional fat-dissolving injections often required more than two weeks before noticeable results were seen, many patients who receive BNLS injections report visible results within approximately 3 days to 1 week.
However, individual results vary, and some patients may take longer to notice changes. Massage and light aerobic exercise may help support the effects of treatment, so we recommend incorporating them 2 to 3 days after your session.
Please note that if you experience significant pain or bruising, massage should be avoided.
② Targeted Fat Reduction Is Possible
BNLS injections can target a wide range of areas—from larger fat deposits such as the thighs and upper arms to more precise areas like the nose and eyelids.
With conventional dieting, you may find that even after losing weight, fat in certain areas—such as the face or legs—remains difficult to reduce. BNLS injections can be directed at specific target areas to help address this concern.
For those who struggle with persistent fat in specific areas despite dieting, BNLS injections may be worth considering.
③ Minimal Discomfort and Short Downtime
Because BNLS injections use plant-derived ingredients as their primary component, post-treatment discomfort, swelling, and downtime tend to be relatively less compared to other fat-dissolving injections. As a result, most patients are able to resume their normal daily routine from the day after treatment.
BNLS injections may be a suitable option for those concerned about swelling or discomfort, or for those with busy schedules who find it difficult to take time off for recovery.
Please note, however, that touching or rubbing the injection site should be avoided. In addition, alcohol and saunas should be avoided for 3 days after treatment, as they may prolong the recovery period.
2 Drawbacks of BNLS Injections

In addition to their benefits, BNLS injections also have the following two drawbacks to be aware of.
- Possible side effects such as bruising, redness, or swelling
- Less suitable for treating larger areas
Understanding these drawbacks will help you determine whether BNLS injections are the right choice for you. Read on for a detailed overview of each.
① Possible Side Effects Such as Bruising, Redness, or Swelling
After receiving BNLS injections, there is a possibility of experiencing pain, bruising, redness, or other reactions at the treated area.
Because plant-derived ingredients are used, the treatment tends to place relatively less burden on the body, and cases of significant redness or swelling are not common. However, individual responses vary, and some patients may experience side effects for several days.
In addition, intense heat, pain, or swelling may indicate a possible bacterial infection. If you notice any unusual symptoms after treatment, please contact our clinic promptly.
② Less Suitable for Treating Larger Areas
BNLS injections are not well suited for patients looking to slim down large areas of the body at once. Administering injections to many areas in a single session places a significant burden on the body, so treating the entire body in one session is not possible.
In addition, fat-dissolving injections work by gradually reducing fat over multiple sessions. Treating a large surface area would therefore require a considerably longer course of treatment.
For those who wish to achieve overall body slimming over a short period of time, other treatment options such as liposuction may be more appropriate.
BNLS Injection Pricing
Pricing for BNLS neo and BNLS Ultimate at our clinic varies depending on the volume injected. Please refer to our diet and body contouring price list for full details.
BNLS Injection Treatment Process
The BNLS injection treatment process is as follows.
- Medical Consultation
First, a physician will conduct a consultation to thoroughly explain the treatment process, approach, and any important precautions. Please feel free to ask any questions or share any concerns you may have. - Treatment Planning
Before administering the injections, we will assess the volume and firmness of the fat in the target area and create a treatment plan and markings to achieve your desired outcome. - Injection
Injections are administered based on the treatment plan. To minimize discomfort during the procedure, a topical anesthetic cream is applied beforehand to numb the skin surface, and the active ingredients are injected carefully and slowly.
After the injections, the marked areas are cleansed and the treated area is cooled before the session is complete.
Frequently Asked Questions About BNLS Injections

If this is your first time considering BNLS injections, you may have some concerns about the procedure. Below we have compiled answers to some of the questions we most commonly receive.
How many days after treatment will I notice results?
With BNLS injections, results often become noticeable within approximately 3 days to 1 week after treatment.
Conventional fat-dissolving injections using “phosphatidylcholine” as the primary ingredient typically require more than two weeks before visible results appear.
In comparison, BNLS injections tend to allow patients to notice changes in a shorter timeframe.
Is there a risk of rebound weight gain?
With BNLS injections, rebound weight gain is uncommon in most cases.
This is because BNLS injections work by reducing the number of fat cells, which may help make it less likely for fat to accumulate in the treated areas again.
With conventional dieting approaches such as calorie restriction or exercise, it is possible to reduce the size of fat cells, but not their number. BNLS injections, on the other hand, work by reducing the actual number of fat cells, which may help support a body composition that is less prone to fat accumulation.
However, individual responses vary, and the degree to which fat cells are reduced differs from person to person. Rebound cannot be ruled out entirely if dietary habits or lifestyle factors are not addressed, so please keep this in mind.
Can I see results from just one session?
Many patients do notice some results even from a single session. To achieve more noticeable results, however, ongoing treatment is generally needed, and we typically recommend a course of 3 sessions at intervals of 1 to 2 weeks.
