Liposuction under the iliac crest, also known as the BIC technique by Below Iliac CrestIt focuses on a very specific area of fat located just below the upper edge of the hip bone. Although it is a small area, it can have a significant impact on the final result of body contouring.
This area defines the transition between the waist, upper hip, and upper buttocks. When the liposuction is performed correctly, the curve appears cleaner, more natural, and more defined. If too much fat is left, the buttocks may appear more square. If too much is removed, a visible indentation may appear along the bony edge.
Therefore, this case should not be understood as a generic page about BBL, hip dips o love handlesThe focus is on a very specific technical area: the exact level of liposuction below the iliac crest.
The difference may be just a few millimeters, but it makes a big visual difference. In the BIC technique, the goal isn't to remove more fat, but to sculpt that area to the right level so that the hip-buttock transition doesn't look square or sunken, but rather defined and harmonious.

Quick facts about the case
Why the area below the iliac crest matters
The iliac crest is the upper edge of the hip bone. The fat just below it creates a visual bridge between the waist, hips, and upper buttocks. When this area is properly sculpted, the transition appears smoother and the buttocks look lifted and more defined.
When too much volume is left in this area, the upper part of the buttocks can appear flat or square, even if volume has been added to other areas. Conversely, when too much is removed, a visible depression can appear because the bony edge becomes too prominent. This is why Dr. Aslani treats this area as a matter of level, not simply the amount of fat removed.
Before and after photos: the core of the case
Too little, too much, right level
This is the most important section of the article. The BIC zone has a very narrow margin: it's not about aspiring further, but about reaching the correct level so that the curve looks natural.
Too little → square
If there is too much volume above the hip, the upper part of the buttocks will appear flat or square. Adding volume will not correct this effect if the buttocks are not properly shaped.
Too much → sunk
If excessive suction is used, the edge of the bone can become skeletal, resulting in a visible depression. This is a delicate area and difficult to correct afterward.
Correct level → defined
Between these two extremes there is an exact level where the transition flows smoothly and the buttocks look lifted, clean and defined.
It's not aggressive liposuction: it's level contouring.
In the BIC technique, the question isn't how much volume can be removed, but rather to what level that band should be reshaped so that the anatomy flows smoothly into the buttocks. This distinction is important because overly aggressive liposuction can disrupt the smoothness of the transition.
The goal is for the high waist, hip edge, and upper buttocks to be perceived as a continuous line. Therefore, this article does not compete with a general guide to... Lipo 360 before and afterThe value here lies in explaining a very specific technical area within the body contour.
It's not the same as hip dips, love handles, or square hips.
These terms may come up in conversation because they refer to nearby areas, but they don't mean the same thing. Liposuction below the iliac crest focuses on the upper edge of the hip and how that area defines the upper part of the buttocks.
Hip dips
Hip dips are lower lateral dips, between the hip and thigh. The BIC zone is higher, just below the edge of the iliac crest. See hip dips guide.
Love handles
Love handles, or rolls, are localized fat deposits on the flanks and waist. They may be close together, but the BIC technique focuses on the hip rim. See the love handles guide.
Square hips
The square appearance can be due to multiple factors. In this case, the key point was the excess level in the band below the iliac crest.
The lesson in one sentence
The shape of the buttocks is determined in a strip a few millimeters below the edge of the hip: If you remove too little, it will be square; if you remove too much, a depression will appear; only the exact level creates a defined and natural curve.

Personalized assessment
Each case depends on the exact level of fat, hip anatomy, tissue quality, and aesthetic goal. A medical evaluation determines whether the BIC area should be treated, preserved, or combined with other body contouring techniques.

FAQ
What is liposuction under the iliac crest or BIC technique?
It is the precise reshaping of the fat pad located just below the upper edge of the hip bone. Its goal is not to remove as much fat as possible, but to adjust the exact level so that the waist-hip-buttock transition appears smooth and defined.
Why can the buttocks look square even after surgery?
Sometimes the cause isn't a lack of volume, but rather fat that remains too thick over the hip area. If this band isn't shaped to the correct level, the upper part of the buttocks can continue to appear flat or square.
Can excessive liposuction in this area create depressions?
Yes. If the suction is applied too low below the iliac crest, the bony edge can become too prominent, resulting in a visible depression. Therefore, this area requires precision and gentleness.
Is it the same as correcting hip dips?
No. Hip dips are located lower, in the lateral area between the hip and thigh. The BIC technique works a higher area, below the iliac crest, which defines the upper edge of the transition to the gluteus.
Can it be combined with BBL or Lipo 360?
Yes, it can be part of a comprehensive body contouring plan, BBL, or Lipo 360. The difference is that this article focuses on a specific technical area: the level below the iliac crest.
