Hello.
I’m Kim Ha-won from Beauty’s Doctor.
When looking for reviews of InMode,
some people say that FX caused significant bruising,
while others say that Forma only felt warm
and caused no particular discomfort,
so it can be confusing to know which is typical.
The two modes above
belong to the same category of radiofrequency devices,
but they deliver energy differently,
so the reactions after treatment should also be considered separately.
When assessing InMode side effects,
it is more important to first check whether the symptoms decrease over time
or instead become worse than to focus on the name of the symptom.
3-Line Summary
- FX uses suction and radiofrequency together,
so circular marks, bruising, or tenderness may occur.
- Forma may leave redness, warmth,
and temporary dryness
as heat is delivered to the skin.
- If pain becomes severe
or blisters, oozing, or changes in skin color appear,
do not wait—contact a medical institution and report your condition.
- What is the difference between FX and Forma?

Forma delivers bipolar radiofrequency
through a tip that remains in contact with the skin
while checking the surface temperature and adjusting the heat.
During the treatment, you may feel as though
a warm device is being rubbed over your skin,
and redness or warmth may remain immediately afterward.
FX, on the other hand, uses negative pressure to draw the skin into the tip
before delivering radiofrequency energy.
Because suction is added,
you may feel the skin being pulled or a brief prickling sensation,
and circular red marks or bruising may appear.
Therefore, rather than grouping Forma and FX together
simply as InMode treatments,
you should first distinguish whether your current concern is skin elasticity
or the thickness of the tissue beneath the chin or in the lower face,
and then determine the areas to be treated.
- Which reactions are common?

After FX, suction marks and bruising,
along with tenderness when pressed or mild swelling,
may temporarily appear.
After Forma, redness and a slight warm sensation,
as well as temporary tightness or dryness,
may persist for a short time.

These reactions generally
show a pattern of decreasing in extent and intensity
over time.
However, the recovery rate
may vary depending on skin thickness, the treatment area, energy settings,
and an individual’s tendency to bruise.
Rather than comparing your condition with the duration mentioned in online reviews,
check whether the redness is lighter than it was yesterday
and whether the tenderness and warmth are decreasing.
- How should you view concerns about hollowing of the cheeks and burns?

When searching for InMode side effects,
concerns about cheek hollowing and burns
are particularly noticeable.
For people with little facial fat or existing hollow areas,
the areas where FX is applied
need to be divided more carefully.
A plan intended to define the area beneath the chin
cannot be viewed in the same way
as a plan that broadly treats the central cheeks.

If a particular area continues to look hollow
even after the swelling has subsided,
or if the difference between the two sides becomes more pronounced,
take photos to document and check the condition.
Because Forma also uses heat,
caution is needed if one area feels unusually hot
and the pain gradually worsens.
If blisters and oozing,

or white or dark reddish-black
changes in skin color appear,
do not dismiss them as simple warmth.
Also contact the medical institution where you received the treatment
if numbness spreads
or your facial expressions feel different from usual.
- What should you check before and after treatment?

Before treatment,
tell the medical staff about any medications you are taking and allergies,
as well as whether you have dermatitis or any wounds.
Information about the areas and timing of
recent fillers and thread lifting,
as well as other radiofrequency, ultrasound, or laser treatments,
is also necessary.
If you have an implanted electrical device or metal implant in your body,
or if you are pregnant,
confirm in advance whether the treatment can be performed.
While warmth and redness remain after treatment,
postpone hot showers, saunas, and Korean-style heated rooms for a while.
It is also better to wait until the skin has calmed down
before resuming strenuous exercise and alcohol,
as well as massages that apply strong pressure to the face and scrubs.
Wash your face gently with lukewarm water
and care for the recovering skin with a mild moisturizer and sunscreen.
In conclusion

Information about InMode side effects
can feel more confusing if the reactions to FX and Forma are not distinguished.
FX may make bruising and marks more noticeable because suction is added,
while Forma may make redness and warmth relatively more noticeable
because it delivers heat.

What matters is not whether a reaction occurs,
but whether it decreases over time
or, conversely, whether the pain and affected area become more extensive.
Rather than following the intensity and number of treatments mentioned in reviews,
check your skin thickness, amount of facial fat, and any pre-existing cheek hollowing,
then determine the appropriate mode and treatment areas.

Frequently Asked Questions
Q1. Is bruising from FX common?
Circular red marks or bruising
may appear during the suction process.
However, if the affected area continues to expand
or pain and warmth worsen together,
visit a medical institution to have your condition checked.
Q2. Does Forma have almost no side effects?
Because Forma does not use suction,
its pattern of reactions may differ from that of FX.
That does not mean there will be no reaction at all;
redness and warmth, dryness, or tenderness
may occur.
Q3. Can I receive InMode treatment even if I have little facial fat?
After checking your skin thickness and amount of facial fat,
as well as any areas of existing hollowing,
the mode and treatment area should be determined.
If you have little facial fat,
a more careful plan is needed to avoid applying FX broadly to unnecessary areas.
Q4. If I develop a blister, can I apply ointment first?
Do not pop it yourself
or apply ointment from home without guidance.
Take a photo and contact the medical institution where you received the treatment
to receive instructions appropriate for your current condition.
