Hello, I'm Dr. Jaeho Cho, Director of TheLINE Plastic Surgery.
Will the treated area become completely smooth after liposuction?
If you pinch your thigh or abdomen, you'll grab fat and skin together in one hold. Liposuction reduces the fat part of that. So what happens to the skin that was covering the fat once it's gone? And is the fat that liposuction reduces all of the fat in your body?
So far, we've looked one by one at what exactly happens to fat cells "Does Liposuction Eliminate Fat Cells, or Just Shrink Them?", whether the firmness felt after liposuction goes away on its own "That Firm Feeling After Liposuction: Will It Go Away on Its Own? (The Truth About Fibrosis?)", cases where body weight is normal but body fat is a concern "My Weight Is Normal: Could I Still? Need Liposuction?", and why certain areas don't slim down even after weight loss "I've Lost Weight: So Why is My Belly Still the Same?". The natural next question is: "So what exactly changes when you get liposuction?"
To get straight to the point: liposuction is a procedure that refines body contour by reducing the volume of subcutaneous fat in the treated area. The elasticity of the overlying skin, the visceral fat deep in the abdomen, body weight, and cellulite are not things liposuction directly changes. In particular, whether the skin smoothly contracts in step with the reduced fat depends less on liposuction itself than on the elasticity that person's skin already has.
What liposuction changes: volume and contour of the treated area
What liposuction clearly changes is the volume of subcutaneous fat in the treated area, and the body contour that results. When you lose weight through exercise or diet, you can't choose where the fat comes off — liposuction directly removes fat from the area you want.
Research has also confirmed that this holds in the treated area. In a randomized controlled trial that followed women for six months after abdominal liposuction, the reduction in abdominal subcutaneous fat in the treated area was maintained through the six-month point, and fat did not refill the treated area[1].
However, changes in the treated area and the total amount of fat in the body need to be looked at separately. In a randomized controlled trial of small-volume liposuction on one area — the lower abdomen, hips, or thighs — in non-obese women, total body fat returned to pre-surgery levels within a year, and that fat showed a pattern of redistribution toward the abdomen rather than the treated thighs[2]. In other words, liposuction reduces subcutaneous fat in a specific area; it is not a procedure that manages the body's total fat over the long term. Weight and overall body fat need to be managed separately.
Why are reducing fat and skin following along two separate things?
How well the skin follows the reduced fat volume is influenced by the skin's elasticity and condition. If the skin has sufficient elasticity, it can contract along with the reduced fat volume; but if there is already sagging or elasticity has declined, excess skin may remain.
A 2021 review in Seminars in Plastic Surgery on deformities after body contouring surgery and their correction identified two cases of skin laxity remaining after liposuction. One is when the skin fails to contract sufficiently after surgery; the other is when liposuction alone is performed on a patient who would have been better suited to skin excision or lifting surgery[3]. The review explains that the many patients who showed more noticeable skin laxity after surgery in the early years of liposuction were largely a result of this patient-selection problem[3].
So does older skin always fail to follow?
Age is often the first thing that comes to mind as a reason skin doesn't follow. On this point, there is a study that measured skin contraction for three months after laser-assisted abdominal liposuction in about 60 patients with mild to moderate skin laxity above the navel. In this study, demographic factors such as age, sex, and body mass index were not significantly associated with the degree of postoperative skin contraction; instead, higher preoperative skin elasticity was linked to better skin contraction[4].
That said, this study observed one area and one technique, in a relatively small number of people over a short period. So rather than generalizing that "age doesn't matter," it's more accurate to take it as a reminder that before judging by the number of your age alone, it's important to directly check your current skin elasticity and degree of laxity.
What else liposuction doesn't change
Beyond skin elasticity, there are three things that fall outside the scope of liposuction and need to be considered separately.
Visceral fat — Liposuction addresses subcutaneous fat beneath the skin; visceral fat around the abdominal organs is not a target of suction. In a study that randomly divided women who had undergone abdominal liposuction into exercise and non-exercise groups and observed them for six months, subcutaneous fat in the treated area did not increase again, but visceral fat increased by about 10% in the group that did not exercise[1]. In the group that exercised, this increase was effectively suppressed[1]. If your abdominal concern comes from visceral fat, liposuction alone won't resolve it, and lifestyle management after surgery is needed as well.
Body weight — A 2015 systematic review analyzing changes in weight and body fat in women who had abdominal subcutaneous fat removed by liposuction or abdominoplasty found that the reductions in weight and body fat after surgery were temporary, fading after a few months[5]. The researchers related this to the body's response of redistributing fat and compensatorily increasing it after fat removal[5]. A reduction of fat cells in the treated area and keeping overall body weight and fat lower over time are two separate matters. It helps to keep in mind that the goal of liposuction is not the number on the scale, but the volume and contour of a specific area.
Cellulite — Cellulite is a dimpled unevenness created when the fibrous septae connecting the skin to the tissue beneath pull the skin downward. Although its cause has not been fully elucidated, substantial clinical evidence indicates that these septae play a central role[6]. According to a 2020 review in Dermatologic Surgery on the pathophysiology of cellulite, a study of 72 women found no cellulite improvement in the ultrasound-assisted liposuction group, and there is also a view that fibrosis after liposuction may create new cellulite or worsen it[6]. However, the review notes that in most cases liposuction neither improves nor worsens cellulite[6]. Because cellulite is a matter of septal structure rather than the amount of fat, it requires an approach different from liposuction.
Individual Variation & Precautions
Skin elasticity and the degree of laxity vary greatly between individuals, so it's most accurate to have your skin condition checked directly through an examination before the procedure.
The more fat that is removed, the greater the range the skin needs to contract to follow along.
If skin laxity is pronounced, other methods such as excisional surgery may need to be considered alongside, rather than liposuction alone[3].
Research suggests that regular exercise after surgery helps suppress the compensatory increase in visceral fat[1].
The studies above analyze the scope of the procedure's effects and do not guarantee any individual's results.
Three Key takeaways
1. Liposuction changes contour by reducing subcutaneous fat volume in the treated area, and that reduction is maintained in the treated area — but it is not a procedure that changes the skin's own elasticity[1][3].
2. How well the skin follows depends heavily on an individual's skin elasticity, and in one study, preoperative skin elasticity predicted outcomes better than age[4].
3. Visceral fat, body weight, and cellulite are not things liposuction directly changes, so it's best to clarify what change you want before your consultation[5][1][6].
Your skin elasticity and the approach that suits it are best confirmed through a direct examination by a specialist. How liposuction is actually performed, including specific surgical techniques, will be covered in the next article.
