Vaser Lipo Complications and Side Effects

What sort of side effects or after-effects are common with Vaser Liposelection? How long do side effects normally last, and how do I know if I need to go back to the doctor? Are there any specific problems that are a definite danger sign?

Issues relative to Vaser Liposelection are mainly the same as with Liposuction in general. One difference is that there tends to be drainage from the incision sites for a day or so after surgery. One good thing is I rarely seen any skin irregularities anymore. I have been doing liposuction for over 20 years and have used Vaser exclusively for many years now. I personally am convinced that results are better with Vaser.

I believe it untrue that there is no pain, bruising, or swelling, but it is true that these issues are reduced. Patients feel and look better quicker, especially if they combine pre and post-op Endermologie. Using Vaser properly takes some time so there is a learning curve. It took me awhile to really learn how to get the most out of this technology. I would suggest you make sure the plastic surgeon you consult with has adequate experience with the equipment to take full advantage of all Vaser has to offer.

To directly answer your question which asks for specific Vaser side effects. Burns! Any ultrasonic liposuction including Vaser (low power ultrasonic) can cause a second or even third degree burn. Otherwise the other frequent side effects from any type of liposuction can apply. I find the Vaser useful primarily in re do liposuction, male chest liposuction (gynecomastia), back areas where the fatty tissue is more fibrotic. Some of the drawbacks to Vaser is no skin tightening, slightly more bleeding and ecchymosis causing a longer healing ( these are my personal findings). Regards.

VASER is extremely safe when used by a well trained experienced surgeon. The side effects are typically swelling which peaks at 48 hours and then gradually disappears by 3 weeks. Skin contraction by 6 weeks is becoming evident, and is usually complete by 14 weeks. This is called lipodermatochalasis and is a powerful effect of VASER lipo. It does take some time to appear though. Other issues can be related to collateral damage to nerves in the skin. The effect is self limited and takes about 6 weeks to subside. It is associated with numbness and ultimately urning sensation along the path of the nerve. "Shark bites" or overzealous aspiration is less common with VASER than other techniques but can occur and will likely improve, but can require fat grafts to correct ultimately. Hope this helps.

As with all liposuction procedures side effects of swelling and bruising can be expected, however they are less with Vaser Ultrasonic Assisted liposuction. Patients will have some degree of initial swelling for the fist 8-12 weeks with the worst being the first 5-14 days. Swelling typically increases as the day progresses. It is not unusual to have morning stiffness when first getting out of bed. Liposuction can often feel like the toughest workout  times 5 for the first few days. I recommend that you receive written post-op instructions from your surgeon to help with commonly raised questions and describe what to contact their practice for between scheduled post-op visits, including the night of surgery. If you have a concern or question or if something just does not feel right do not hesitate to contact your surgeon, even after office hours or on weekends. Most practices are happy to address any post-op concerns and prefer that you call rather than not as sometimes serous complications require earlier attention, Although rare, possible complications with all liposuction procedures, including Vaser, can occur including but are not limited to: bleeding, infection, asymmetry, under or over liposuctioning of areas, injury to internal organs, seroma, failure of the skin to redrape well, skin contour irregularities or waviness, need for revision surgery, deep venous thrombosis (DVT), pulmonary embolus (PE) and death. Vaser patients may also experience temporary numbness or tingling of the skin in the treated areas as a result of the ultrasonic sound waves effect on the sensory nerves. If this occurs it is short lived and typically insignificant . In inexperienced hands complications such as burns of the skin may rarely occur. That is why one should seek a consultation with a Board Certified Plastic Surgeon well versed in this reliable and safe procedure.

Are there side effects or after effects of VASER lipo?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Hi there-

While I do personally believe that the VASER represents the safest and most effective tool for accomplishing lovely, natural improvements in body contour, it is critically important for you to realize that the tool used is not nearly important as the surgeon using it on you.

The surgeon you choose will make a much greater difference on the outcome you achieve, AND on the risk of having a complication.

I think that too many people make the mistake of believing that with the latest liposuction machine in their hand, ANYONE (for example an eye doctor or gynecologist) could achieve a safe and pleasing outcome for them- but unfortunately this is not the case.

Find a surgeon certified by The American Board of Plastic Surgery (how to know?- check here:

If you find a surgeon with the above credentials and some experience using the VASER, your risk of complications is very low, and the chances of being happy with your outcome very high. The most common problems are very minor ones that take care of themselves over time, like swelling that takes a bit longer to go away than the patient would have preferred. Skin irregularities are extremely rare with the VASER, but again, the technique and my education, training, and experience as a Board Certified Plastic Surgeon are part of the reason why.

Side effects after VASER

VASER liposuction is an extremely safe procedure.  Side effects are rare.  Some of the common after effects include swelling which can last up to 3 months.  Numbness is the area which was liposuctioned can last 6-8 weeks, but usually resolves.  In my practice, I have not seen any burns on the skin, but this is sometimes reported as a side effect after Vaser liposucion.  I have also not seen any infection after VASER.  I, however, leave many of the skin port holes open to drain.  This seems to prevent infection and fluid collections from forming under the skin.  Uneveness or area of skin irregularites is also rare after VASER and is much more common with traditional liposuction.
