Venus Freeze treatments

I recently had a breast reduction with upper arm liposuction 5 months ago.  The lipo reduced my arm circumference by 2 inches! Very happy with that but due to my age of 55, I have lost that youthful elasticity leaving my skin a bit lax.  My PC suggests the Venus Freeze to tighten the skin.  My question is, has anyone had this done following liposuction and any concerns since I still have some numbness and skin sensitivity.  Its a bit pricey but am willing to try if it is safe to do this early post lipo.  Appreciate any feedback!
