Philtrum Botox (Lip Flip): How to Refine the Midface Without Shortening the Philtrum

Let me start with the core of philtrum Botox, often referred to as a Lip Flip. Philtrum Botox is a non-surgical procedure that injects a very small amount of botulinum toxin into the orbicularis oris muscle, which is the muscle inside the upper lip, to gently roll the upper lip line outward. Because it temporarily relaxes the muscle tension rather than cutting away the skin or tissue of the philtrum, the actual physical philtrum length is not reduced. However, by making the red part of the upper lip appear slightly fuller, it can create the impression of a shorter distance between the nose and the lips, giving the middle of the face a more refined look.

So, before worrying about whether you need to cut the philtrum, it is worth considering this as a non-surgical option to refine your appearance first. The procedure takes only about 5 to 10 minutes, and there is almost no downtime, allowing you to return to your daily routine immediately on the same day. However, you must keep in mind that this is not a permanent procedure, and because the lips are a very sensitive area, precise dosage control determines the outcome.

🔎 How exactly does philtrum Botox work?

Botulinum Toxin Type A works on the principle of preventing the release of a neurotransmitter called Acetylcholine at nerve endings, temporarily blocking muscle contraction. When muscles relax, the skin and tissues above them relax as well.

The main muscle where the toxin is injected in philtrum Botox is the **Orbicularis Oris**. When this muscle is slightly relaxed, the upper lip, which used to roll inward when smiling or talking, rolls slightly outward. As a result, the exposure above the Vermilion Border (the border of the lip mucosa) increases, making the upper lip look plumper and giving the relative effect of a shorter philtrum.

The injection points are 2 to 6 points around the Cupid's Bow, just above the upper lip. The dosage used is very small, roughly **4 to 10 Units** based on the upper lip. If you also worry about a gummy smile where your gums show excessively, the **Levator Labii Superioris**, which lifts the upper lip, may also be considered.

📌 Key Summary: Philtrum Botox works on the principle of slightly relaxing the orbicularis oris muscle to roll the upper lip outward and make the philtrum appear shorter. It is a procedure that changes your impression, not one that physically reduces length.

⏱️ When do the effects appear, and how long do they last?

The effects do not appear immediately. You will start to feel the effects gradually 2 to 5 days after the procedure, reaching the maximum effect in about 1 to 2 weeks. Therefore, there is no need to feel disappointed or anxious when looking in the mirror on the day of the procedure.

The maintenance period is on average 2 to 4 months. However, because the area around the lips is highly active due to eating, talking, and smiling, the duration may feel shorter—around 2 to 3 months—than other facial areas. The toxin naturally breaks down over time, and the muscles return to their original state.

If you are considering maintenance procedures, it is helpful to have another consultation just before the effect completely disappears (around 2.5 to 3 months) to stably maintain the line.

📌 Key Summary: Effects start 2 to 5 days after the procedure, peaking in 1 to 2 weeks, with an average duration of 2 to 4 months, which may feel shorter due to lip characteristics.

💉 Philtrum Botox vs. Lip Fillers vs. Philtrum Reduction Surgery

Even though they may look similar, these procedures have different purposes and principles. Let's organize them into a table.

A lip flip and lip fillers can also be performed together. Muscle relaxation (Botox) and adding volume (filler) are often used together to achieve synergy. On the other hand, if your philtrum is structurally long and you want physical shortening, philtrum reduction surgery can be discussed, but it carries the burden of incision, recovery, and irreversibility. If structural issues are not significant, we recommend exploring non-surgical options to refine your look before going under the knife.

📌 Key Summary: Fillers are for volume, Botox is for muscle relaxation, and surgery is for permanent shortening. Since only fillers can be reversed, Botox should be approached carefully, starting with small doses.

⚠️ Side Effects and Precautions

Side effects are rare if the dosage is well-controlled, but if an excessive dose is injected, functional discomfort can occur.

• Feeling that pronouncing lip plosives like 'b', 'm', and 'p' is awkward

• Difficulty using a straw or a feeling of water leaking when drinking

• Facial asymmetry when smiling

• Drooling, discomfort during meals

Although rare, adverse reactions such as difficulty swallowing, difficulty breathing, and systemic muscle weakness may occur. If you experience these symptoms, contact a medical institution without delay.

In particular, those whose lip function is professionally important, such as announcers, singers, lecturers, and wind instrument players, must approach this more cautiously. If you have a history of drooling, swallowing disorders, or neuromuscular disease, you must inform us in advance. Botulinum toxin cosmetic procedures are not recommended during pregnancy or breastfeeding.

📌 Key Summary: Overdosage can lead to pronunciation and expression discomfort, and those with professions requiring lip function, or who are pregnant or breastfeeding, should be cautious. In case of severe adverse reactions, contact a medical institution immediately.

🧬 Products, Tolerance, and Good Things to Know

There are several types of botulinum toxin products used in Korea. These include the original Botox (Allergan) and Xeomin, which is free of complexing proteins.

Here is a common misconception: Because potency and dilution methods differ for each product, simply comparing the number of 'units' across different products is not accurate. 1U of Botox and 1U of another product cannot be assumed to produce the same effect. Therefore, rather than judging solely by the unit number, what your goal is, how much is injected, and where it is placed are much more important.

Another thing: Repetitive, high-dose, or too-frequent procedures can lead to a decrease in effectiveness due to the formation of neutralizing antibodies, causing tolerance. It is best not to get injections more often or in larger quantities than necessary. For reference, botulinum toxin procedures are classified as medical procedures in Korea and can only be legally performed at medical institutions.

📌 Key Summary: Units cannot be simply compared between products, and frequent, high-dose procedures increase the risk of tolerance. Small doses and appropriate intervals are the rule.

✨ Onlif's Approach — Refining, Not Altering

Gangnam Onlif Clinic does not aim for plastic surgery that changes the shape of the eyes, nose, and mouth, but rather points towards bringing out your natural balance. The same goes for the philtrum and lips. The goal is not to cut and shorten the philtrum, but to carefully relax muscle tension to naturally refine the impression of the midface.

Onlif focuses on non-surgical treatments from a dermatological perspective. We aim for moderate improvement through procedures such as lip/nasolabial fold fillers, Botox, skin boosters, and thread lifts. Based on the philosophy that one doctor cannot do everything perfectly, we operate a medical specialty system where doctors in charge perform the procedures they excel at most.

For sensitive areas like the philtrum, a conservative approach of starting with a small dose and making judgments after recording expressions (expressionless, smiling, and side profile) from various angles is key to reducing side effects.

📌 Key Summary: Onlif prioritizes 'refining' the philtrum non-surgically rather than 'altering' it, and operates on the principle of a small-dose, conservative approach.

❓ Frequently Asked Questions (FAQ)

Does philtrum Botox actually shorten the philtrum?

The actual length of the philtrum is not reduced. It is closer to a visual change where the philtrum appears shorter as the upper lip slightly rolls out due to the relaxation of the orbicularis oris muscle. If physical shortening is desired, other methods should be considered.

When will I feel the effects, and how long do they last?

The effects appear gradually 2 to 5 days after the procedure, reaching maximum effect in 1 to 2 weeks. The average maintenance period is 2 to 4 months, and because the lips move a lot, it may feel shorter, around 2 to 3 months.

If I don't like the results, can I reverse it immediately?

Unlike fillers, there is no way to instantly erase Botox. While fillers can be dissolved with hyaluronidase, you must wait for Botox to naturally dissipate over time. Therefore, it is safe to start with a small amount.

Can my pronunciation become awkward or can using a straw become difficult?

This is rare with appropriate doses, but if an excessive dose is injected, the pronunciation of plosives like 'b', 'm', and 'p' may become awkward, and using a straw or drinking water may become uncomfortable. It recovers over time.

Can people with occupations where pronunciation is crucial, like announcers or singers, receive this?

It is not impossible, but they must be extremely cautious. If lip function is professionally important, it is recommended to approach with a very small dose, or decide after sufficient consultation on whether to proceed at all.

Can I receive it at the same time as lip fillers?

Yes, it is possible. Combined procedures that aim for synergy by using muscle relaxation (Botox) and adding volume (filler) together are common. They are performed individually or in combination depending on the goal.

Will I develop tolerance if I get it frequently?

Repetitive, high-dose, or too-frequent procedures can increase the risk of developing tolerance, where effectiveness decreases due to the formation of neutralizing antibodies. It is best to receive them only as needed and at appropriate intervals.

Can I receive it while pregnant or breastfeeding?

Botulinum toxin cosmetic procedures are not recommended during pregnancy or breastfeeding. If you have plans for a procedure, you must inform us of your condition through a consultation beforehand.

Philtrum Botox, What to Check Before Choosing a Clinic

Even for the same procedure, the results and recovery process can vary depending on where, by whom, and how it is performed.

Asking these questions during your consultation can help you make a decision.

• Do they perform this procedure frequently? — Every clinic has different procedures they focus on. Check if it is a place that regularly performs philtrum Botox.

• Can I verify the products and equipment used? — Ask if you can verify the product name and authenticity (whether it is an officially imported product and if there is a process to confirm its unsealing) during the consultation.

• Do they explain the cost breakdown? — Rather than just hearing the total amount, you need to hear an explanation of what product, how much, and on which area it is used to make a proper judgment.

• Do they design the treatment looking at the entire face? — Even for the same procedure, the injection points and amount vary depending on the facial shape, skin condition, and left-right asymmetry.

• Do they explain adverse reactions and the recovery process first? — It is better to choose a place that informs you of potential adverse reactions and how to handle them, rather than a consultation that only speaks of expected positive changes.

• Is there a way to follow up after the procedure? — Check if there is a set timeline for checking progress, a way to contact them if there are issues, and criteria for follow-up visits.

This is how Onlif Clinic performs philtrum Botox

• We divide responsibilities — Based on the philosophy that one doctor cannot handle every procedure, Onlif divides medical treatment among specialized doctors for each field.

• We verify products and equipment together during consultations — We guide you through the products used and the process of verifying their unsealing during the consultation process.

• Costs are guided along with the plan after diagnosis — Since the area, dosage, and range differ for each person, we explain what costs how much together.

• We design treatments looking at the balance of the entire face — We view the face through three axes: texture, balance, and youth signals, and plan in a direction that cleans up the parts overshadowing your natural impression rather than changing its shape.

• We inform you of adverse reactions and the recovery process first — Along with the changes you can expect, we guide you through individual differences, potential adverse reactions, and countermeasures before the procedure.

• We monitor progress together after the procedure — If checks are needed during the recovery period, we guide you through follow-up visits and contact channels.

If you are considering philtrum Botox, it is best to check first what is possible and what is difficult in your current condition.

An accurate diagnosis and treatment plan can only be determined through an in-person medical examination. Confirm it through a consultation at Gangnam Onlif Clinic.
