A firm, voluminous buttock line is one of the important factors that determine overall body balance. However, many people are concerned about sagging buttocks or reduced volume due to various causes, including dieting, weight fluctuations, and reduced skin elasticity with age.
The shape of the buttocks is not determined by fat volume alone. It is also influenced by the muscles, fat, skin elasticity, and skeletal structure. Therefore, even with diligent exercise, sagging skin or insufficient volume may not improve as much as desired.

Squats and hip exercises can help strengthen the buttock muscles, but they may have limitations when the buttocks are naturally lacking in volume or the buttock line has been affected by changes in body shape.
One option that may be considered in such cases is #HipLiftSurgery.
Recently, rather than simply aiming to make the buttocks larger, more people have come to value natural hip-line design that also takes the waist, pelvis, and leg lines into account.
Why do sagging buttocks develop?
Is it simply due to insufficient fat?

It is difficult to explain the cause of sagging buttocks in terms of just one factor. Common causes include reduced skin elasticity with age, loose skin remaining after weight loss, reduced buttock fat, insufficient muscle mass, poor posture and lifestyle habits, and naturally determined body-shape characteristics. In particular, when weight decreases rapidly during dieting, buttock volume may also decrease as fat is lost.
In addition, insufficient volume in the upper buttocks can create the impression that the lower portion is sagging, and it may also affect the overall silhouette when wearing clothes. At this point, the important thing is not simply to add volume, but to identify the sagging areas and areas lacking volume in order to create a balanced shape. Hip lift surgery is a surgical approach tailored to each person’s condition to address these body-shape concerns.
Hip Lift Surgery Method ① Fat Transfer
A method that naturally adds volume using your own fat

Fat-transfer hip lift surgery involves harvesting fat from your own body and injecting it into the areas where it is needed. Fat is generally collected from areas such as the abdomen or thighs, purified, and then transferred to the buttocks. The main characteristic of the fat-transfer method is that it uses your own tissue.
✔ Natural-feeling texture may be expected
✔ Creates soft lines suited to your body shape
✔ The body-contouring effect of the fat-harvesting area may also be considered
Fat transfer may be considered particularly when someone wants “natural-looking volume rather than an overly artificial appearance.” However, because some of the transferred fat may be absorbed, it is important to establish a surgical plan that takes each person’s fat volume and fat-retention rate into account.
Hip Lift Surgery Method ② Implant-Based Hip Lift Surgery
For cases requiring definite volume enhancement

Implant-based hip lift surgery creates volume by inserting specially designed implants into the buttock area. It may be considered when it is difficult to achieve the desired size change with fat transfer alone or when a clear increase in volume is desired.
✔ The desired increase in volume can be planned
✔ Can be used to design the shape of the buttocks
✔ Can be considered even for body types with little fat
For people with a slim body type who do not have enough fat in the buttocks, implants may be one option. However, with implant surgery, it is also important to select the size and position according to the individual’s skeletal structure and buttock shape. Rather than choosing implants that are unconditionally large, considering the proportions and harmony of the entire body is key to achieving a natural result.
Fat Transfer vs. Implants: What Are the Differences?

Both methods aim to create a hip-lift effect, but their approaches differ.
Fat-Transfer Hip Lift Surgery
-
Uses the patient’s own fat
-
Natural-feeling texture may be expected
-
Body-contouring effects may also be considered
-
Fat volume and retention are important
Implant-Based Hip Lift Surgery
-
Creates volume with implants
-
Allows the desired volume to be designed
-
Can be considered for body types with insufficient fat
-
Implant selection and positioning are important
There is no single method that is definitively better. The appropriate method may vary depending on the individual’s body shape, the desired degree of change, fat volume, and skin condition.
What Is Hybrid Hip Lift Surgery for Natural-Looking Lines?

Recently, an approach that combines the advantages of both methods has also been considered. Hybrid hip lift surgery uses implants and fat transfer together. It creates the basic volume with implants and uses fat transfer to enhance areas that lack volume or need refinement of their contours.
For example, the central volume of the buttocks may be created with implants, while the surrounding lines are naturally refined with fat transfer. Rather than simply increasing size, this method aims to create a natural curve extending from the waist to the pelvis and buttocks. Because the areas requiring adjustment can be tailored to the body shape, it may be considered for people who want a natural-looking hip line.
Another Method for Natural-Looking Volume:
What Is BiVOL Hip Lift Surgery?

Recently, approaches that differ from conventional methods, such as BiVOL hip lift surgery, have also attracted attention. The BiVOL method is known as an approach that uses highly biocompatible materials to encourage volume formation through a natural response from the body’s tissues.
Rather than simply filling a space with an external substance, it aims to create natural-looking volume that harmonizes with the surrounding tissues over time. Various hip lift methods may be considered depending on the individual’s body shape and desired direction of change. The important thing is to choose a method suited to your own physical condition.

Sagging buttocks are not simply a matter of insufficient exercise; various factors, including skin elasticity, fat distribution, and muscle structure, may have an influence. Therefore, when considering hip lift surgery, the important process is not determining “which method is best,” but finding the method suited to the current shape of your buttocks and the results you want.
A beautiful hip line is completed not by size alone, but by a design that is proportionate to and harmonizes with the entire body. If you are concerned about sagging buttocks, it is important to accurately understand your body shape and goals, consult thoroughly with a medical professional, and choose an appropriate method.
