Buccal Fat Injections: Why Less Means More Sag
Dissolving buccal fat isn't enough—loose retaining ligaments can sag more without combo treatment.

Deep jowl fat-dissolving injection results,
why reducing the amount can actually make sagging worse
Please check this before reading
Q. If only the deep jowl fat is dissolved, will the V-line come back?
A. It depends on the case.
If the supporting ligaments are lax, simply reducing the amount
can make it look even looser, like empty skin.
Q. Then when and how do the effects appear?
A. Line changes usually become visible from the 2nd to 3rd session.
In cases with sagging, whether lifting is combined
makes a clear difference in the results.

Deep jowl fat-dissolving injections,
how far does the real effect go?
Deep jowl fat-dissolving injections
are a procedure that breaks down and removes fat located in
the deep layer beneath the jawline (deep jowl fat)
with medication.
But even when the issue is the same "jaw sagging,"
the causes are different.
If it is a fat-dominant type, injections alone can define the line,
but if the cause is muscle or ligaments,
reducing the volume will not restore the line.
This is because the skin layer targeted by lifting treatments such as
Ulthera or Shurink
is completely different.

Why do some people look
even more saggy after reducing the amount?
"The sagging of the bulldog jowls is
not because there is more fat, but
because the supporting ligaments have loosened.
If you only reduce the volume with fat-dissolving injections,
it can actually look even more saggy,
so the jawline improves when lifting is combined."
— Dr. Wi Young-jin (Beautystone Clinic, Hongdae)
A 53-year-old patient who visited us last week had received
deep jowl injections six times at another clinic.
At first, her face seemed slimmer, but
after the fourth session,
she felt the area beside the corners of her mouth had become even looser.
The fat had decreased, but the cause was
loosening of the retaining ligaments
that support the skin.
Once the space filled by fat was emptied,
it sank downward like empty skin.
When bulldog jowls sag, it is often not because there is more fat,
but because the ligaments have stretched
and the fat has descended.
If the cause is the ligaments and you only treat the fat,
the structure will inevitably look even hollower.

A customized guide that determines
deep jowl treatment results by type
Check which type you fall into.
Type | Characteristics | Recommended approach |
Pure fat type | 20s to 40s, good skin elasticity | Fat-dissolving injections alone, 3–4 sessions |
Sagging type | Late 40s and older, pronounced bulldog jowls | Lifting first, then injections as an adjunct |
Muscle type (masseter) | Becomes firm and protrudes when biting on the molars | Square-jaw toxin first recommended |
In the clinic, we check both the lying position
and the seated position.
If the sagging disappears when lying down,
it is more likely a ligament-laxity type than
a fat type.
Before deep jowl injections, here are three questions we hear most often
Q1. Will I see results with just one treatment?
Only about two or three out of ten people are
satisfied after one session.
The actual reduction accumulates from the second session,
and most people clearly notice the difference
around the third session.
Q2. How long do the results last?
If your weight stays stable,
the results usually last about 2 to 3 years.
However, if you gain more than 5 kg,
the remaining fat cells can swell again,
which may blur the contour, so caution is needed.
Q3. Are there any side effects or precautions?
Swelling and bruising for 3 to 5 days after
the procedure are normal reactions.
However, if the injection is placed too superficially
without considering the nerve pathway,
it can cause mouth asymmetry or accelerate sagging
.
This is why it is important to have the skill to
accurately identify the anatomical layer.
If you remember just one thing today,
— with deep jowl treatment, the result depends less on
how much is reduced and more on whether the ligaments are supporting it.
In the next article, we'll explain the most effective order when
Shurink and deep jowl injections are done together.
