The Truth About Kendall Jenner Videos and the Isotretinoin Nose-Reduction Effect

"People say that if you take isotretinoin, your nose gets smaller. Is that true?"

"I got curious after watching a video about Kendall Jenner."

For a while, stories about "taking isotretinoin and having a smaller nose" have circulated often on social media and short-form video platforms.

In particular, many people asked whether a medication alone could really change the shape of the nose, using videos of celebrities as examples.

To get straight to the point,

isotretinoin alone does not cause structural changes such as the nose bone shrinking or spread cartilage coming together.

However, some people may feel that after taking it, their nose looks less swollen than before,

and that the tip looks a little more refined.

Today, at MOOi Plastic Surgery,

we’ll explain the difference simply so you don’t get it confused.

The claim that "taking isotretinoin makes your nose smaller" has gone viral online—how much of it is true? Questions about isotretinoin use and nose-reduction effects

What does isotretinoin actually do?

Isotretinoin is originally a medication used to treat acne.

Simply put, it helps reduce sebum production

and calms the environment where inflammatory breakouts keep recurring.

So if you usually have a lot of sebum around the nose, or if red inflammation and swelling often appear there,

after taking the medication, the skin on the nose may look less oily and less swollen than before.

This is why many people feel that their nose has gotten smaller.

But that is closer to a change in skin condition, swelling, and oiliness.

It does not mean the structure itself has changed.

Isotretinoin may affect inflammation, sebum, and swelling, but it is not a medication that reduces the nose bone or cartilage itself

Why do some people really feel like their nose has gotten smaller?

In particular, for people with thick nose skin and active sebaceous glands,

the nose tip can look slightly swollen all the time, making it appear larger than the actual structure.

When inflammation and sebum decrease in this state, the surface can look much smoother,

and the outline of the nose tip may appear a bit more defined.

In other words, it is closer to "the elements that made it look thick have calmed down" than to "the size has decreased."

There can be a change in the way it looks from the outside,

but it does not happen to everyone to the same degree, and it is clearly different from structural reduction.

After taking isotretinoin, if inflammation, swelling, and sebum decrease, the overall volume can settle down and the nose may look less bulky (explaining isotretinoin effects and reasons)

There may be other real reasons why the nose looks larger

In reality, the reason a nose looks large is often not only due to the skin.

If structural factors are significant, such as a wide nasal bridge bone, spread tip cartilage, or a flared columella–alar line,

you may not get the change you want with medication alone.

That is why some people see almost no change even after taking isotretinoin,

while others may feel that the nose tip looks a little more refined.

This is because the approach changes completely depending on whether the issue is the skin,

the structure, or both.

The reason a nose can look large is not only the skin, but also structural factors such as a wide nasal bridge bone and spread tip cartilage (explaining structural reasons a nose can look large)

Then what approach is appropriate in these cases?

If the nose skin is thick and oily, making the tip look especially congested,

an approach that first stabilizes skin condition may be helpful.

On the other hand, if the bone and cartilage themselves are wide or spread out,

you need a consultation in a direction that addresses the structure.

What matters most is not starting the medication on your own just because of a single sentence you saw online.

There are many things to check before taking isotretinoin, and side effects must also be monitored.

In particular, if you are considering rhinoplasty, you must tell the doctor in charge in advance about any history of taking dermatology medications.

Frequently Asked Questions (FAQ)

Q. Does taking isotretinoin really reduce the nasal bone?

A. You should not understand it as the nasal bone or nasal cartilage actually shrinking.

However, as sebum, inflammation, and swelling decrease, the visible fullness can change, so it may feel like it has gotten smaller.

Q. Then can I take isotretinoin instead of nose surgery?

A. No. If the nose looks large due to structural reasons, medication alone will not easily create the change you want.

Medication has its own role, and surgery has its own role.

Q. Can it help if I have thick nose skin?

A. If the skin is thick and sebaceous gland activity is high, it may help to some extent in refining the appearance.

However, whether to take it and when must be decided only after a medical consultation.

Q. Is it okay to take it just by looking at SNS reviews?

A. No, we do not recommend that.

Isotretinoin is a medication that requires medical evaluation and monitoring.

Online cases should be used only as reference, and the decision to take it should be made in the clinic.

To summarize

• Isotretinoin may affect sebum, inflammation, and swelling.

• So the nose may look less bulky, and you may feel that it has gotten smaller.

• But it is difficult to change structural causes such as the nasal bone or cartilage with medication alone.

• Only after distinguishing between a skin problem and a structural problem can you decide whether medication or a consultation is the right direction.

The nose creates its impression through both "visible thickness" and "internal structure."

Even if it looks similar on the outside, the causes may be different,

so we recommend visiting a clinic to accurately check why your nose looks large.
