Do you use a different filter size with the body tip?

Hello Paul, No you don't need to use a different size filter. The body (the white part of the tip) is the same diameter as the other diamond tips. This just has a bigger head to allow for a bigger surface area to get covered. Hope this helps! Rowena Trophy Skin

What all comes with this?

Hi Jellybean! This is our Large Diamond Tip for use on the body, arms, and legs. This is an optional accessory for our Trophy Skin microdermabrasion devices such as the MicrodermMD, RejuvadermMD and MiniMD. Our MicrodermMD and RejuvadermMD comes with the standard diamond tip, pore infusion tip and pore extraction tip. The MiniMD only comes with the standard diamond tip. We offer this Large Body Tip as an optional accessory to make microdermabrasion on larger surface areas easier and quicker. I hope this clarifies your question. Thank you! Rowena Trophy Skin

How long does it take for the initial charge ?

I doesn’t need to be charged. You just 🔌 and it turns on.
