Is RF Microneedling over saline breast implants safe? Implants are under the muscle.

I'm curious if under-the-muscle older saline breast implants will pose any problem with treating the breasts using microneedling radio frequency ("MnRF") with a 25 pin head at a needle depth of 1.5mm with a minimum depth of 16 mm (0.5 inch + 3mm) from the skin's surface to the implants; breasts have very thin skin with 30+ year old severe stretch marks. Has anyone had experiences treating breasts with implants using MnRF?
