I’m getting VASER lipo with skin tightening J Plasma, but still concerned with excess skin after surgery. I am a 25 yr old male.

It depends on how much fat is removed. For procedures such as a tummy tuck, there is often a lot of excess skin due to the amount of fat that is removed. On the contrary, VASER lipo to stubborn areas like the arms or flanks doesn't usually result in excessive loose skin, this way J plasma or renuvion skin tightening is a viable option. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.

Patients who have significant skin laxity need skin removal with open surgery.This generally means a tummy tuck for the abdomen.I own a Renuvion device and have found it to under Deliver and be fairly uninspiring for skin tightening. It’s better than not using it but the amount of skin tightening is actually fairly minimal. I don’t believe this is my lack of skill but rather that this and all other previous attempts of non-surgical skin tightening continue to be unimpressive.Well done Liposuction generally doesn’t make the skin looser. It does deflate the envelope and the skin can look a bit different.  take a look at my liposuction results posted under my profile on real self. You’ll see patients with significant skin laxity which shows only Liposuction and you can get an idea of what results look like for those who didn’t have great skin to start with.skin laxity is in my opinion the number one reason patients fail to get a good liposuction results.The reason for this is to fold. Loose skin is often perceived as being fat by many people. They pinch or recruit their skin When showing how much body fat they have. Often the skin laxity is the problem not body fat. Since skin laxity is not treated by Liposuction the results tend to be weak because the primary problem isn’t treated and the primary problem as perceived as being a different problem.The best way to assess how thick your fat layers is to put your skin under tension and gently pushing until you feel the underlying muscle or bone structure. It’s also important to recognize that skin laxity contributed significantly to body contour. When that’s the case removing the fat isn’t going to change the body contour all that much. Another way to assess for this is to pull up on the skin, put it under tension and see if this changes the contour to a more desirable shape. If it does then skin laxity is for sure a big part of the equation.If the contour looks the same when the skin is under tension and most likely fat manipulation will have a much greater impact.Male weight loss patients typically don’t do all that great with Liposuction but that is a very general statement.Instead, the ideal Liposuction candidate is a tight pudgy younger woman who hasn’t had children. anytime the primary problem is excess subcutaneous fat and there are no other variables contributing to undesirable contour Liposuction will deliver.Best, Mats Hagstrom MD
