NB Inner Thigh · Flow Design
A thigh gap is not a space created by removing a lot of inner fat alone. It is a lower-body design that looks at the whole-leg line together — the inner line, the above-knee flow, the hip-to-thigh connection and left-right balance.

Even the same inner-thigh concern leads to a different design direction depending on the above-knee area, the pelvic connection and left–right balanceWhy It Matters
A thigh gap is not a space created by removing a lot from the inner thigh; it is closer to a result that emerges after looking at the inner thigh, the above-knee area and the pelvis–thigh connection together.
Line Approach
Even with the same thigh and the same inner fat, the line turns out completely differently depending on the perspective. We have summarised the difference between reducing the inner side only and looking at the whole-leg flow.
"How the whole-leg flow will connect" comes before "how much to remove from the inner side"
Design Principle
We do not look at the inner side as a single plane. The inner line, the above-knee flow, front and back thickness, the connection with the pelvis and left–right balance all have to be seen together for the whole leg to connect naturally.
01Inner thigh line
After precisely assessing the thickness and position of the medial fat layer, we draw the line for how far and how much to refine. It is not simply removing a lot, but the work of creating a flow.
02Above-knee finishing
Removing only the inner thigh strongly can make above the knee stand out relatively. We look at the above-knee flow together and design it so the thigh falls smoothly toward the knee.
03Front and rear thickness balance
The thigh is a three-dimensional structure where the inner, outer, front and rear surfaces all move together. Reducing only the inner side can make the front-rear thickness difference stand out, so we look at the balance between the surfaces together.
04Hip-to-thigh connection
The connecting line where the thigh start meets the hip and under-buttock determines whether the leg looks long. If the connecting area is broken, the space can look awkward even when the inner gap is created.
05Left-right balance
The fat distribution and muscle development of the left and right thighs are often not the same. Looking at only one side as the reference can leave the two out of alignment, so we compare both legs together in planning.
The actual design scope can differ depending on individual body type, fat layer thickness, muscle development and prior procedure history.
Structural Zones
The space between the legs is not determined by inner fat alone. Pelvic-floor width, pelvic-floor muscles, the under-buttock line and the position of the pubic area can all have an influence, so we check them together at the assessment stage.
01
The width of the pelvic floor (perineum) needs to be sufficient to form the basic structure that can create inner space. If the width is narrow, the sense of space can look different even when the same amount is removed.
02
The impression of the inner space can vary depending on how well the pelvic-floor muscles support the pubic area and the structures within the pelvis.
03
When the under-buttock sags, the space above the thigh start looks filled in. The clearer the under-buttock line, the more the inner flow comes alive.
04
The volume and position of the pubic area can also influence the impression of the groin space. When needed, it is considered together with the feminine line.
The four factors carry different weight from case to case. Priorities and scope can change after an actual assessment, and not every factor becomes a target of the procedure.
Body Design Finder
An inner-fat-centered type, a complex type where above-knee and under-buttock are also involved, and a structural-analysis type where pelvic structure and prior procedures play a role — the design direction can differ by type, so organizing your own type before consultation helps.
The online assessment is not a definitive medical diagnosis but a guide tool to organize your own inner thigh concern type before consultation.
Check my thigh typeWhy NB
A thigh gap is not the work of emptying a space, but the process of designing the flow of the whole leg
01
Whole Leg Flow
Whole-leg flow analysis
We do not look only at the inner thigh. We analyze the whole-leg flow together — the inner thigh, above the knee, the hip-to-thigh connection and left-right balance.
02
Layered Design
Layer-by-layer precise design
The medial fat layer differs in thickness by position and thins out toward above the knee. We design the depth and range differently by area.
03
Hip-Thigh Connection
Consideration of the hip-to-thigh connection
Drawing on our experience with Heoeongmu (thigh, under-buttock, knee) integrated design, we ensure the whole-leg line continues naturally in the process of creating a thigh gap.

Direct analysis and surgery by the specialist
Body line design calls for different judgment in each case. A body-contouring specialist with 25 years' experience personally analyzes, designs and operates.
Type → Plan
Medial thigh fat typeThe inner thigh fat is thick · The pelvic width is fairly sufficient · The under-buttock and above-knee are relatively tidy
→Type A
Design direction
We center on precise suction of the inner line and look at the above-knee flow together.
Request a consultation →Complex line typeThere is inner fat along with above-knee or under-buttock involvement · The thighs spread sideways when sitting · The overall sense of leg thickness bothers you
→Type B
Design direction
We design the inner thigh, above-knee and under-buttock lines in an integrated way.
Request a consultation →Type needing structural analysisThe inner thigh is not especially thick, yet the space between the legs looks closed · A sense of narrow pelvic width or accompanying under-buttock sag · There is a prior procedure history
→Type C
Design direction
We precisely analyze the pelvic-floor structure, under-buttock and prior procedure history, then decide the direction.
Request a consultation →Even for the same "thigh gap", the whole-leg line is drawn differently in each case
Design Process
This is not simply a matter of removing a lot from the inner side. Following the order of assessment → line mapping → layer-by-layer precision liposuction → left–right balance finishing, we apply a different design perspective at each stage so that the whole-leg line connects naturally.
STEP 1
DiagnosisWe assess the whole leg — the inner fat layer, above-knee thickness, pelvic width, under-buttock line, left-right asymmetry and prior procedure history.
STEP 2
Line MappingWe map the inner line for how far, how much and at what depth to refine, and draw the above-knee finishing and the hip connection points together.
STEP 3
SculptingWe design the suction range and depth differently according to the medial fat layer thickness. We refine it so the inner flow falls naturally toward above the knee.
STEP 4
Balance FinishWe finish while comparing both legs together. Reflecting left-right differences in thickness and muscle, we adjust the line so it continues as a matched pair.
Expected Lines
These items are not intended to guarantee results; they are guidance summarising what line changes are typically observed in a design that considers the whole-leg flow together.
Inner line refinement
A flow where inner chafing eases when walking
Above-knee finishing
A line that falls smoothly from thigh to knee
Hip-to-thigh connection
A flow where the leg start continues without breaking
Front and rear thickness balance
A three-dimensional leg line even seen from the side
Left-right balance
A proportion where the two legs continue as a matched pair
Clothing line refinement
A silhouette that falls cleanly in trousers, skirts and swimwear
Actual line changes can differ depending on fat layer thickness, muscle development, pelvic structure, skin elasticity and prior procedure history, and the same result is not guaranteed in every case.

Case Review
Inner fat thickness, above-knee flow, pelvic width, under-buttock line and prior procedure history can look similar on the outside yet call for a different approach. Referring to cases with similar concerns can help you make your own direction more concrete before consultation.
Cases are not material to guarantee results but reference material to understand thigh line types and design directions. The actual plan may change after consultation and assessment.

Recovery & Care
The inner thigh, above the knee and around the under-buttock are areas with a lot of movement and friction, so swelling and bruising can appear, and compression and aftercare may be needed for the period advised.
Day 1–3
Compression garment worn, walking possible; care for inner-thigh chafing areas
Week 1
Return to daily life; avoid long-distance walking and intense exercise
Month 1
Swelling decreases; the inner and above-knee line contours begin to show
Month 3
The line settles; final refinement needs more time
01
To stabilize the inner and above-knee line, compression stockings or a compression garment may be needed for the period advised.
02
The inner thigh and above the knee are areas with a lot of movement, so early swelling and bruising can appear, and the swelling may look as if it moves downward.
03
To support tissue recovery and ease firmness, aftercare programs such as radiofrequency can be combined step by step.
04
It is good to adjust long-distance walking, strenuous exercise and strong stretching step by step while watching your recovery.
05
The speed and pattern of line refinement can vary depending on skin elasticity, cellulite and any prior adhesion.
06
The recovery process and final line vary by individual depending on fat layer thickness, muscle development, pelvic structure and the scope of surgery.
The content above is general recovery guidance, and the actual management plan and recovery period may vary by the scope of surgery and individual recovery status.
FAQ
The inner thigh line can call for a different approach depending on individual fat layer, above-knee flow, pelvic structure and prior procedure history, so it is important to check the range and limits together before consultation.
The degree to which it is possible can vary depending on pelvic width, pelvic-floor muscle support, any under-buttock and pubic-area sagging, and the state of the inner fat layer. Even with the same inner fat, a different structural condition changes the approach, so a direct assessment is needed.
When there is a lot of inner fat and the structural conditions support it, inner suction alone may produce a change. However, because the above-knee flow, under-buttock and pelvic width also play a role, an approach that looks only at the inner thigh can have limits.
Removing only the inner thigh excessively can make above the knee stand out or the leg line look awkward, so it is important to design the range while looking at the inner, above-knee and front-rear thickness together.
The inner thigh flow finishes above the knee. Evaluating the above-knee thickness and degree of sagging together lets us design the whole leg to continue more naturally.
When under-buttock sagging is involved, inner suction alone can have limits, so under-buttock line correction or a lifting procedure can be considered together. The direction may vary depending on the case.
Many people find friction eases when walking once the inner fat is refined, but how much you feel varies by individual depending on body type, posture and lifestyle habits.
The thigh 360° flow and thigh gap design are connected to each other. It can proceed as an integrated design that looks at the inner, front, rear, above-knee and under-buttock at once.
When there is adhesion, fibrosis or unevenness from a prior procedure, the approach can vary, so we decide the direction of revision or line correction after assessment.
