Hello.
This is Kim Gaeul from Hapjeong Station Dermatology Clinic.
Ultherapy continues to be well loved because it can improve both firmness and contour
without making an incision in the skin.
However, even a little searching will easily turn up reviews about side effects such as
Ultherapy cheek hollowness or burns.
Even if you are looking into it with the expectation of good results,
anyone would hesitate after seeing stories like these.
To help ease those worries today,
by using genuine tips and making precise energy adjustments,
we will explain how to prevent side effects such as burns and cheek hollowness,
and how to safely achieve lifting results. Haha.
🔍 The Principles and Effects of Ultherapy

Ultherapy is a lifting procedure that uses high-intensity focused ultrasound (HIFU)
technology to deliver energy
all the way to the SMAS fascia layer, the deep layer of the skin.
At this time, ultrasound creates tiny thermal coagulation points inside the skin,
causing proteins to denature and tissue to contract,
which produces the effect of lifting sagging skin.
During the recovery process after the procedure,
the production of new collagen is stimulated,
so you can also expect the added benefit of improved skin texture and elasticity.
However, if the energy is too strong
or the depth is not adjusted accurately,
side effects may occur.
Typical side effects include the following.
🔍 Ultherapy cheek hollowness (depression caused by damage to the fat layer)
🔍 Burns (when energy is concentrated near the epidermal layer)
🔍 Temporary swelling, nerve irritation
⚠️ Preventing Ultherapy Side Effects
① Precise energy adjustment
Above all, the precision of the energy settings
is important.
Even when using the same device,
results can vary greatly depending on the practitioner’s skill
and understanding of the skin layers.
For example,
for people with thin skin or little cheek fat,
it is safer to use a 3.0 mm
or 1.5 mm tip rather than a deep 4.5 mm tip
and stimulate mainly the dermal layer.
On the other hand, areas with a thick fat layer,
such as under the chin or a double chin,
are more effective when targeting deeper layers.
In this way, if energy is distributed and delivered by layer according to skin thickness,
fat distribution, and muscle structure,
side effects caused by overheating of the fat layer can be prevented.
💎 Preventing Ultherapy Side Effects
② Check whether genuine tips are used
The second most important thing
is whether genuine tips are being used.
The tip used in Ultherapy is a key component that delivers ultrasound energy,
and genuine tips automatically have a limited number of shots,
stopping operation after a certain number of uses.
However, if counterfeit or reprocessed tips are used,
energy output becomes uneven,
causing heat to concentrate excessively in certain areas,
or, conversely, reducing effectiveness.
This can then lead to Ultherapy side effects.
By contrast, genuine tips provide
📌 consistent energy maintenance
📌 even heat distribution
📌 safe shot-count management
which greatly reduces the risk of skin damage.
Therefore, before undergoing Ultherapy,
📌 whether the device is certified as genuine
📌 the tip’s usage history
📌 shot-count limit management
these three things must be checked.
Hapjeong Station Dermatology Clinic uses only officially certified devices
and transparently manages tip usage records.
💬 Q&A

Q1. If Ultherapy cheek hollowness occurs,
will it recover over time?
Mild Ultherapy cheek hollowness
will gradually recover over several months through the collagen regeneration process,
provided the fat layer has not been completely damaged.
However, if fat cells have actually been destroyed,
recovery may be slow, so early management is important.
Q2. If Ultherapy cheek hollowness occurs,
should I go to the hospital right away?
Yes, you should visit the clinic
as quickly as possible.
If diagnosed early, skin boosters or
regenerative care programs can help
support tissue recovery.
The longer it is delayed, the higher the chance that the hollowing will become fixed.
Q3. To prevent Ultherapy cheek hollowness,
what kind of clinic should I choose?
📌 Use of genuine devices
📌 Customized settings
📌 Experienced practitioners
Choose a place that meets
these three standards.
A clinic that carefully analyzes the skin layers and adjusts the treatment depth
during the pre-procedure consultation is safer.
Today, I talked about Ultherapy cheek hollowness, which many people worry about,
focused on its causes and prevention methods.
In summary,
1️⃣ Accurate energy adjustment
2️⃣ Use of genuine tips
3️⃣ The experience of skilled medical staff
These three things
are the key to Ultherapy without side effects.
If you are considering Ultherapy at Hapjeong Station Dermatology Clinic,
please receive a consultation that considers both safety and satisfaction.
Thank you for reading.
