Is lipo effective for inner thighs, if I have sagging skin there?

Hello,Unfortunately, without an examination or at least photos, you can not expect an intelligent answer. Please visit a few ABPS certified/ASAPS member surgeons capable of performing not only liposuction, but all body contouring procedures; they will be most honest about the possibilities and limitations of liposuction.  Best of luck!

The inner thighs are very delicate areas to treat with liposuction. The skin is usually thin, with less elasticity than skin in other areas. That means that the surgeon must be more conservative and cautious in these areas. For inner thigh liposuction to produce a noticeable and satisfactory improvement, the skin must be of fairly good quality and elasticity. If it's very stretched and sagging, the results will likely be poor with liposuction alone. A procedure to excise and tighten skin (thigh lift) would then be advised.

You raise a good point liposuction and sagging skin. Liposuction does well in patients who skin is elastic and can shrink after the fat is removed. As sagging skin is present before liposuction is performed, then liposuction will only make the sagging worse. In that situation a removal procedure is recommended, such as a thigh lift.

I find that VASER hi def contouring combined with thermiRF is the best in this area. I suggest you see only an expert as there are a lot of problems that can occur if the procedure is done improperly.  Best, Dr. Emer.

Hello dear, thanka for your post and provided information as well. 

Thigh lift surgery reshapes the thighs by reducing excess skin, and in some cases fat, resulting in smoother skin and better-proportioned contours of the thighs and lower body.

If fitness and weight loss efforts have not achieved your goals for a body that is firmer, more youthful-looking and more proportionate to your overall body image, a surgical lift may be right for you.

Good candidates are:

People whose weight is relatively stableIndividuals with excess soft tissue along the inner or medial thigh region and/or the outer thighHealthy individuals who do not have medical conditions that impair healing or increase risk of surgeryNon-smokersIndividuals with a positive outlook and realistic goals for what thigh lift surgery can accomplishIndividuals committed to leading a healthy lifestyle, including proper nutrition and fitness

I recommend to contact a certified plastic surgeon to talk about your goals. 

Good luck :)
