How to Reduce Side Effects and Get Better Results from Hongdae Corner-of-Mouth Botox

Hello. I’m Dr. Jo Wonjin, and I’ve been practicing medicine for 10 years.

I got corner-of-mouth Botox done wrong,

and now only one side lifts when I smile ㅠㅠ

If you chose the procedure to make your expression look brighter, but smiling has instead become stressful, that disappointment is beyond words.

Today, under the topic of how to reduce side effects and get better results from Hongdae corner-of-mouth Botox,

I’ll explain why side effects from corner-of-mouth Botox happen, how to address them, and what to keep in mind to improve results.

5. What is corner-of-mouth Botox?

The principle behind Hongdae corner-of-mouth Botox is simpler than you might think.

The muscles in our face are constantly in a tug-of-war.

The muscles that lift the corners of the mouth and the muscles that pull them downward are firmly opposed to each other.

The green muscle in the photo is the depressor anguli oris.

At this point, the key is to inject a small amount of medication into the depressor anguli oris, which strongly pulls the corners of the mouth downward, and weaken that force.

As the downward pulling force weakens, the upward lifting muscles become relatively stronger,

so the corners of the mouth appear to lift slightly even when you are at rest.

2. Side effects of corner-of-mouth Botox and how to prevent them

Although the procedure itself may seem simple, the area around the mouth is a region that constantly moves as we speak and eat,

so preventing side effects is especially important.

Mouth asymmetry The most common side effect after Hongdae corner-of-mouth Botox,

You’ve probably seen cases where the mouth looks pulled to one side or becomes crooked when smiling.

This happens because the medication moves beyond the target muscle, the depressor anguli oris,

and affects nearby muscles.

That is why conservative design is important.

In particular, the smaller the lower face and the narrower the facial area, the more densely packed the muscles are.

Even a slight misplacement can easily lead to the so-called Nike-shaped asymmetric mouth.

So in such cases, we set the injection point slightly lower and more outward.

This secures a safety margin so that other facial expression muscles are not affected.

Unnatural facial expression The second issue is when the area around the mouth feels stiff, as if paralyzed, or when it seems like saliva might leak.

This occurs due to an error in Botox dosage control or an incorrect depth adjustment.

Because the area around the mouth requires calculating even very shallow muscle movements,

rather than injecting a large amount at once, the muscle movement must be examined in detail and the injection layer chosen carefully.

The key is to avoid injecting too much.

3. Tips for getting better results from corner-of-mouth Botox

Hongdae corner-of-mouth Botox is a procedure that requires more detailed diagnosis and adjustment than it may seem.

So to get the full effect, you need to pay attention to the following.

First, if one side is already lower or the muscle strength differs between sides, you should not inject the same amount on both sides.

To achieve symmetry, the dosage must be distributed differently depending on the strength of the muscles on each side.

Second, with Botox, how it is diluted is just as important as the product itself.

If it is diluted too much in an attempt to increase the volume,

the diffusion range becomes wider,

and the medication may spread to unintended areas,

while the effect itself may also be insufficient.

On the other hand, if it is too concentrated, side effects can occur.

Wouldn’t it be reassuring to receive it only when the hospital follows the proper mixing ratio?

Third, for about one week after the procedure, you should avoid rubbing the area around the mouth vigorously or getting lymphatic drainage massage.

This is to prevent the medication from spreading before it settles in place.

Also, if you consciously reduce habits such as firmly biting your lips or closing your mouth with downward tension,

you can maintain the effects of Botox much longer.

4. Frequently Asked Questions (Q&A)

Q. Does it hurt a lot?

A. Since a very thin injection needle is used, it feels like a slight prick. The procedure also takes only about 5–10 minutes, so it barely interferes with daily life.

Q. When do the effects start to appear?

A. Although it varies by person, you can usually feel the muscles relaxing and the mouth area becoming lighter about 3–7 days after the procedure, and the most natural effect appears after 2 weeks.

Q. How long does it last?

A. It usually lasts about 3–4 months. If you receive another treatment before the effect completely fades and before the muscle strength begins to return, the corrective effect can last even longer.

If you did not get the desired effect as described above,

it may also be a good idea to look at the post below and choose a suitable clinic.

Today’s 3-line summary

• Hongdae corner-of-mouth Botox is a procedure that creates a smile by weakening the muscles that pull downward

• To prevent asymmetry side effects (the Nike mouth), especially for a smaller lower face, a more conservative approach with a lower and more outward injection point is needed

• It is not about injecting exactly the same amount for everyone; accurate diagnosis and dosage adjustment based on each person’s muscle strength are the key

Even if just one corner of the mouth lifts slightly, the overall impression of the face can look different.

I hope today’s information helps you bring out the best features of your face in the most natural way.

Thank you. This has been Jo Wonjin.
