Read this page to the end and you will understand why your arm looks the way it doesARM LINE PLANNING
Even the same upper-arm concern can call for a different plan depending on the outer, inner and rear arm, the front and back of the armpit, and the bra line.
Arm 360 reads the outer, inner and rear arm and the line above the elbow separately, but connected into one arm silhouette. The U-line is the concept of reading not the upper arm alone but the front and back of the armpit, the accessory breast, the bra line and the rear upper body together. The surgical plan can differ with your fat layer, a muscular arm, the structure of the shoulder and armpit, and skin firmness.
ARM 360 · U-LINE MAP
Thinning one part of the arm does not by itself make the line natural. The line settles without breaking only when you read together how the front, rear, inner and outer surfaces of the arm join, and how the U-line flows from the arm into the armpit, the bra line and the back. NB decides the direction of the line design after assessing both together.
Arm 360 Surfaces
01
The surface seen first from the front. As it meets the straight line of clothing, even a slight change in flow can read as thickness, so we read it as the starting point of the whole line, not thickness alone.
02
The surface that feels gravity first, where the effects of skin firmness and sagging appear together. We diagnose firmness and flow together, rather than fat volume alone.
03
The surface that moves most when you raise or wave the arm. A flow invisible in a still pose can appear in a dynamic one, so we read movement too.
04
The surface where the flow that joins the shoulder is decided. We reflect the start and end of the line in the design direction so the connection to the shoulder line is not broken.
U-Line Connections
01
When only the arm is thinned, the border with the armpit can stand out. We read the two areas together so the inner flow of the arm runs naturally into the armpit.
02
The armpit and bra line meet the line of clothing and underwear directly, so they are the connecting area where a difference in flow shows first. If only the arm is tidied and this area remains, it can stand out — so we read it together.
03
The rear arm is part of the flow that runs on into the back line. Even if the back of the arm looks natural in isolation, a broken flow into the back can make the rear silhouette read awkward — so we read it together.
Four-surface design and three-connection design are not a standard operation applied identically to everyone, but a diagnostic view that reads the line together. The actual extent of surgery is decided after assessing your fat layer, skin firmness, muscle use, adhesion and the state of the connecting areas.
BODY DESIGN FINDER
An outer arm, inner-arm sag, rear-arm volume, flesh front and back of the armpit, and the bra-line connection may each call for a different plan. You can organise your own type before the consultation.
The online check is not a medical diagnosis. It is a guide for organising the type of your arm and upper-body concern before consultation.
Check my arm typeWHY ARM FAT IS DIFFERENT
The nature of outer-rear fat
The fat on the outer and rear arm has progressed into cellulite, with fibrous tissue tangled through it. Unlike ordinary fat, it is not removed by exercise or dieting.
Gravity and skin sagging
Fat on the back of the arm sags easily under gravity. Removing fat alone may not be enough, so sagging and skin firmness have to be assessed together to help tidy the line.
The 360° connected structure
The front, side, rear and armpit of the arm are one connected line. Reduce only one direction and another stands out more. An all-round 360° design is needed.

An outer arm, inner-arm sag, rear-arm volume, flesh front and back of the armpit, and the bra-line connection can look alike but call for different approaches. Looking at cases with a similar concern helps you shape your own direction before the consultation.
Cases are not material for showing a result. They are reference for understanding arm and upper-body types and directions of planning. The actual plan can differ after consultation and assessment.
ABOUT ARM LIPOSUCTION
Before
After
A slimmer arm is the point A smooth, straight-falling line An arm that reads natural from any angle in 360°
NB METHOD
STEP 1
VASER2 · AnalysisEmulsifying cellulite with VASER2
VASER2 ultrasound energy is applied to the fibrosed cellulite fat on the outer-rear arm to dissolve the hard fibrous tissue first. This step is the key to even removal.
STEP 2
Handmade + PowerHandmade + power, suctioned together
The hand feel of a 25-year surgeon (handmade) and rotational power liposuction are combined where each belongs. Delicate areas by handmade, broad areas evenly by power.
STEP 3
BodyTite · OptionalBodyTite alongside where sagging is present
Where there is sagging, BodyTite RF tightening is done at the same time as the liposuction. It contracts the skin without excision for a smoother result.
It is not which method is used but when and how — that is the skill of a 25-year surgeon
U-LINE · BONUS EFFECT
When the accessory breast, armpit flesh and rear-fold flesh (the U-line) are planned together with the arm liposuction, an armpit gap appears. An armpit gap is the space that appears between the arm and the torso when the arm is lowered. Like a thigh gap, an armpit gap makes the whole silhouette read far slimmer and more elegant.

The silhouette separates and reads slimmerWHY NB
01
VASER2 for cellulite
The fibrosed cellulite fat on the outer-rear arm is hard to remove evenly with a standard cannula alone. NB emulsifies the fibrous tissue with VASER2 first, for a more even and smoother result.
02
All-round 360° line design
We design the front, side, rear and armpit of the arm as one connected line. Remove only one direction and another stands out. NB makes a straight-falling arm with balanced all-round 360° suction.
03
Handmade + power, 25 years of practice
For delicate arm areas the surgeon's hand feel matters. A surgeon with 25 years of experience combines handmade technique and power liposuction, each where it belongs, case by case.
04
Sagging and the U-line, planned as one
This is not simple fat removal. Where there is sagging we consider BodyTite; where the armpit area is a concern we consider a U-line design. We plan the whole arm as one flow.

RECOVERY
RECOVERY CARE
The upper arm, the front and back of the armpit and the bra line move a great deal, so swelling care, compression, radiofrequency aftercare and activity control all have to be considered after surgery.
01
To settle the arm line and manage swelling, an arm compression garment or band may be needed for the period you are advised.
02
Around the arm and armpit, early swelling and bruising can appear, and the swelling can seem to move.
03
Aftercare programmes such as radiofrequency may be used alongside, to help tissue recovery and ease firmness.
04
Light everyday movement may be possible, but strong arm exercise or upper-body strength training is better increased in stages, watching how recovery goes.
05
How quickly and in what way the line settles can differ with skin firmness, sagging, cellulite and any existing adhesion.
06
Recovery and the final line vary from person to person, with the fat layer, muscle mass, armpit structure and the extent of surgery.
The following is general recovery guidance. The actual care plan can differ with the extent of surgery and your individual recovery.
FAQ
Will my arm fall straight after arm liposuction?
If only the arm is tidied, the flow with the armpit, bra line and back connection can read awkward. NB plans by reading the arm 360° together with the connecting areas, but the actual extent depends on your fat layer, skin firmness and the state of the connecting areas. Whether it is possible is explained after consultation and assessment.
Does the uneven cellulite on the back of the arm improve too?
The wobble and unevenness on the inner and rear arm can involve changes in skin firmness and inner tissue flow together, more than fat volume alone. The degree of wobble and the direction of approach can differ with your skin condition and tissue flow, so it is explained after assessment.
Is it possible if I have arm sagging?
We design the incision to the smallest possible extent, but depending on the recovery process and your skin, a mark can remain. NB manages it together through recovery care and aftercare so the mark settles as naturally as possible.
Can the U-line (armpit area) be done together?
The accessory breast, flesh front and back of the armpit, and rear-fold flesh can look connected to the arm line, so they are often assessed together. The actual extent of combining depends on the upper-body structure, the fat layer, skin firmness and the state of the connecting areas. Whether it is possible is explained after consultation and assessment.
Can it be corrected if only one side is thick?
A difference in thickness or line between the sides can arise from the activity of the arm you use more, fat distribution and differences in tissue flow. We assess each side separately and design toward balance, but rather than aiming for the two sides to become identical, we prioritise a natural balance of flow.
How long does the line last?
The line takes several months to settle, and how it is maintained afterwards can differ with skin firmness, weight change, lifestyle and the pace of ageing. Rather than the moment right after surgery, NB manages the process by which the line settles naturally, together with you.
This is general guidance and does not replace a medical examination.
