Although the lips are a small part of the facial features, it is not just the upper and lower lips that matter. The surrounding muscles, the corners of the mouth, and the philtrum must also be in harmony. Looking at philtrum reduction surgery, you can see that as this area, which was long, becomes shorter, the lip line changes as well, and the three-dimensionality and sense of length of the face are also improved. In the reviews for A-top Plastic Surgery, both the inner and outer areas are improved together so that the overall lip shape, facial proportions, and length can all be improved, creating a natural-looking impression.

Inner and outer philtrum

The central part of the philtrum that we usually refer to is the inner area, which is the sunken part that curves inward. It corresponds to the vertically grooved area extending from below the nose to above the lips. This area sits vertically along the centerline of the face, and in philtrum reduction surgery, it is the main point where length is adjusted and three-dimensionality is refined.

The outer area refers to the slightly raised lines located on both sides of the inner philtrum. It is the pillar-like part and serves as a contour line that surrounds the area around the lips and the sunken part of the philtrum. Depending on the volume and definition of this area, the appearance of the lip line and the three-dimensionality of the philtrum can change, so it is an important part.

For this reason, the inner and outer philtrum should be operated on together. When the face looks long, reducing the inner area can make it appear relatively shorter, and when there is a lack of three-dimensionality and it looks flat, the surgery should preserve the outer lines so that philtrum reduction surgery can look natural and attractive.

It is not simply a reduction surgery that only shortens length; for facial three-dimensionality, proportions, and a natural lip line, inner and outer procedures must be performed together. Only then can you expect improvements in a natural lip shape and mouth line, as seen in the A-top Plastic Surgery reviews.

Designing to an ideal ratio

Philtrum reduction is different in purpose, principle, surgical process, and method from a simple procedure that pulls up sagging skin or performs a lift. This area, located at the center of the face, is both noticeable and a key factor that determines the overall impression and proportions, so it must be designed with precise ratios and balance in mind. Even just a few millimeters can change the harmony, proportions, and sense of length of the face. Carefully compare philtrum reduction surgery and have the procedure done with a customized design suited to you at a place with sufficient surgical experience and know-how.

In general, this area is ideally adjusted so that the ratio of the length from below the nose to the upper lip and the length to the chin is about 1:2 to 1:2.5. This can make the face look more three-dimensional and give a natural, youthful impression. The ideal length is usually around 10 to 10.5 mm, but this is only a guideline, and detailed adjustments are necessary depending on each person’s bone structure, facial length, proportions, and lip anatomy.

If the design takes into account the overall vertical proportion of the face, the position of the lips, and the length to the tip of the chin, a natural result can be expected. In particular, if you focus only on shortening the philtrum, the result may look unnatural and disrupt the balance of the entire face. The length may be reduced, but the upper lip can appear unbalanced and too thick, or the cupid’s bow may stand out sharply, making it look artificial. The corners of the mouth may also appear droopy, or the smile may become unnatural, so caution is needed.

In addition, it can also affect the length of the chin and the degree of tooth exposure. For this reason, rather than operating on the philtrum alone, it is important to design the procedure while considering the overall harmony of the face and the appearance of the mouth line.

A natural operation with no visible incision line

To shorten the philtrum, an incision is made along the line below the nose. Rather than making a straight incision, the cut is made in a contoured, irregular shape to match the curves, so the scar can be kept as inconspicuous as possible. However, a delicate incision rather than an excessive one is necessary. After that, the tissue that has sagged downward is pulled upward and fixed in place with sutures.

If lifting is performed at the same time by enhancing the curve of the upper lip in this process, the line connecting the nose, philtrum, and lips becomes more natural, resulting in a prettier and more three-dimensional side profile. If the reduction is too excessive, the upper lip may curl up too much, so after the incision, only a moderate amount of lifting should be done to create a soft philtrum and lip line.

Because the incision is made below the nose, it is especially important not to affect the shape of the nostrils or the line of the nasal tip. If the shape of the nose is distorted, it can look unnatural, so consulting with medical staff who understand the anatomical structure of the nose and mouth well can help achieve a natural and attractive philtrum reduction surgery that is barely noticeable.

A beautiful appearance is influenced not only by attractive facial features, but also greatly by overall proportions. In the case of a satisfying philtrum reduction surgery at A-top Plastic Surgery, only the necessary amount is reduced appropriately, and the procedure is performed so that the scar is not easily noticeable. Rather than rushing to reduce as much as possible, the surgery should be designed according to each person’s facial proportions. After sufficient consultation, I hope you can improve to a natural, attractive, and ideal proportion with a 1:1 customized design suited to you.
