Sagging in Your 40s? Time for Ultherapy Lifting
Why Ultherapy suits your 40s: SMAS Layer changes, cases, honest notes on Shurink, sessions, cost.

If you suddenly start looking saggy in your 40s,
now is the right time for Ulthera
Please check this before you read
Q. Isn’t it too early
or too late if you’re in your 40s?
A. To be honest, the early to mid-40s
is the period when Ulthera works best.
It’s the key stage to support the SMAS layer
just as it starts to weaken.
Q. Isn’t Shrink enough?
Do I really need Ulthera too?
A. It varies by case,
but if fat sagging has started,
the treatment depth is different, so the approach is different.
I’ll explain in detail in the main text.

Ulthera vs. Shrink: the key difference in your 40s
Ulthera is a lifting procedure that delivers
ultrasound energy precisely to the SMAS layer
at a depth of 4.5 mm to directly contract the fascia.
People often confuse it with Shrink,
but while Shrink is also in the HIFU category,
its main depth is around 1.5–3.0 mm.
Simply put, if Shrink focuses on tightening
the dermis and fat layers,
Ulthera grasps the fascia layer underneath and
holds the tissue itself upward.

Why do you suddenly look saggy starting in your 40s,
do you know?
Director Wi Young-jin’s key insight
After your 40s, the SMAS layer connections weaken
as fat sagging becomes more pronounced,
so Ulthera’s fixed lifting effect is especially effective.
There are so many cases like this
that I’ll note one down separately.
Last month, a 47-year-old woman came in,
and she said, “Until last year I was fine,
but this year the area under my cheekbones
suddenly collapsed.”
She held up a mirror and gently lifted it with her hand,
saying, “If it could just go up this much,” and
that is exactly the typical complaint of people whose
SMAS layer has weakened.
This is a point many people misunderstand,
but sagging in your 40s is not because the skin gets thinner.
The real cause is that the SMAS layer
(superficial musculoaponeurotic system) becomes looser.
This layer acts like a hammock that
holds facial fat up in place,
but once you enter your 40s, the collagen and elastin bonds
weaken rapidly.
So the buccal fat and jowl fat sitting on top of it
begin to sag downward.
That is the essence of line changes in your 40s.
This is why Ulthera is especially
effective at this stage.
The 4.5 mm transducer accurately reaches the SMAS layer
and creates a thermal coagulation point (TCP) at 65–70°C,
causing the fascia to contract immediately,
and then over the next 3 to 6 months, collagen is reorganized,
which re-secures the tissue.
That 47-year-old patient came back
three months after one treatment,
and had almost recovered to the position
she had lifted with her own hand.
But that doesn’t mean it’s always perfect.
Ulthera can be quite painful during the procedure,
and if you have thin fat, your cheeks may
temporarily look more hollow after treatment.
Still, in the early to mid-40s,
when the SMAS layer has started to weaken
but fat and skin volume are still intact,
it remains the most proven option.
Director Wi Young-jin’s key summary
Sagging in your 40s is not because the skin becomes thinner,
but because the SMAS layer connections weaken,
causing fat to slide downward.
Ulthera is almost the only non-surgical device that
reaches that SMAS layer (4.5 mm) directly,
so it works best at this stage.

So, is Ulthera right for me?
Type | Features | Recommended approach |
Early 40s, initial sagging stage | The line under the cheekbones starts to collapse slightly | Ulthera alone, about once a year |
Mid to late 40s, noticeable fat sagging | Nasolabial and marionette lines form | Ulthera + Shrink combined, at 6-month intervals |
Thin face with little volume | Risk of looking hollow after treatment | Adjust Ulthera shot count + consider combining with filler |
If you have a thin face,
reducing the number of shots or distributing the depth
is much safer.
Last week, a 53-year-old patient came in with a similar case,
and instead of going all in with full shots,
we adjusted it while checking her fat volume,
so the line was improved without the cheeks hollowing out.
If you’ve read this far,
you’re probably wondering this
Q1. Once you get Ulthera,
how long does the effect last?
This is a bit tricky,
so it’s hard to say exactly, “It lasts for X months.”
Right after the procedure, there is an immediate contraction effect for about a month,
and over the next 3 to 6 months,
many people gradually improve more
as collagen regenerates.
On average, you can think of it as lasting 8 to 12 months,
but there are big differences depending on your aging speed.
Q2. Please be honest about the cost and
the proper number of sessions
To be honest,
the standard recommendation for people in their 40s is once a year.
The price varies depending on the number of shots,
but around 300 shots is a reasonable full-face standard.
First-time patients often ask, “Wouldn’t two or three sessions in a row be better?”
but Ulthera doesn’t work that way.
You need to give enough time after one stimulation
for collagen to build back up before the next one becomes meaningful.
Q3. Are there any side effects or precautions?
But when you actually see patients in the clinic,
the most common thing is a feeling like muscle soreness
for a few days after the procedure.
In rare cases, there can be temporary bruising, or
in areas with thin fat,
the volume may look slightly reduced.
One important thing I must mention:
if it is shot incorrectly along a nerve pathway,
there is also a risk of temporary facial paralysis,
so it is really important to be treated by a doctor
who understands anatomy precisely.
In the next article, I’ll talk about “the real changes seen in the clinic during the first two weeks after Ulthera in your 40s.”
I’ll show with cases why the point at which people feel the effect differs.
If you’re unsure about the number of shots or the depth,
please send a side-view and front-facing photo on WhatsApp.
