Would microneedling after CoolSculpting be beneficial to encourage treatment effectiveness and fat loss?

microneedling will not help fat removal however doing trsculptFLEX with the coolsculpting and /or RF like venus legacy or forma can help. I would suggest seieng an expert.  liposuction maybe a better options for you too.  
If you have small problem areas you can use non invasive methods like coolsculpting with vanquish or TrusculptID to get small areas of fat reduced.  Skin also tightens if you combine this with exilis ultra, venus legacy, Inmode Forma/Contoura radiofrequency treatments.  You boost the results from coolsculpting if you add in Kybella injections to melt fat as well.  We also combine coolsculpting with shock therapy like Z wave, EVIVE, and cellutone to get even faster results, more improvement, and less risk of combinations like nodules, swelling, neuropathy or paradoxical hyperplasia.  Best, Dr. Emer.

If you are looking to reduce fat in the area by about 25%, CoolSculpting should provide you with a very good result. In my practice, we follow up CoolSculpting treatments with Z Wave at no additional charge. Z Wave delivers sound waves to the treatment area to provide additional smoothing and tightening. Make sure the doctor performing your treatment is board-certified and has extensive experience with the CoolSculpting device to ensure an optimal outcome. 

I do not believe that micro needling or topical products would have any influence on the effectiveness of CoolSculpting.  CoolSculpting can reduce fat, but micro needling and topical products would not penetrate deep enough to have any effect on the fat.  Those treatments could help with the skin however.  

For my patients that don't desire surgery and have reasonable quality skin, we can sometimes do "Fire and Ice". This is a combination of ThermiSmooth (non invasive radiofrequency that feels like a hot stone massage) and Coolsculpting for fat reduction. Coolsculpting results may be a 25% fat reduction per applicator and sometimes two treatments need to be done in the same area for maximal results. Plus the ThermiSmooth can also be slimming with some skin improvement. Make sure to find someone with experience with layering techniques. 

Dear hailyeah:I understand your concerns, but you don’t need to worry that CoolSculpting will not be effective. It reduces fat in treated areas by 20 to 28% in every treated patient (the higher percentage is achieved with after-treatment massage).  One of the unique features of CoolSculpting is its reliability and the reproducible results. If you wish to enhance your results and help with additional loss of fat both beneath the skin as well as within the abdominal cavity, you could combine CoolSculpting with Emsculpt, which increases muscle mass and reduces subcutaneous and visceral fat. ThermiSmooth or another radiofrequency treatment like PelleFirm or HIFU with Ultherapy would tighten the skin if your problem is laxity rather than excess fat, but will not reduce fat. It sounds like you need an in-person consultation with someone who has these devices to see how you should proceed.All the best!Sheryl Clark MD FAAD

Microneedling will not help with fat reduction in any way.  However, combining coolsculpting with a heat based procedure such as Vanquish ME, Exilis Ultra or Warmsculpting can give a nice "fire and ice" combination procedure and work even better for fat reduction.  Additionally, using Zwave afterwards (shock wave therapy) will further enhance results.  You are on the right track thinking about combination procedures as it greatly enhances results when procedures are used concurrently.  

 The effectiveness of cool sculpting is marginal at best. But without a good set of photographs or an in-person consultation, it is difficult to tell you if it will be beneficial for you personally. You should be evaluated by a plastic surgeon who will give you his opinion and recommendations that are suitable to your needs. I hope this helps and good luck from New York City plastic surgery
