Neuderma Fibroblast Plasma Pen Used twice. Retails at $350. All 5 star reviews online. Really works, I just never have time to use it, and own 100+ beauty devices and I get PRP facials so I don't need this. Works on moles, dark spots, sun spots, skin tags, removing dark circles under eyes, collagen production stimulatio, anything. Works the same way fibroblast / plasma skin treatments work with a cosmetologist (which cost $300-600+ per facial). Has settings of 0-9 so works on all skin types (I have bi-racial tan skin, and it doesn't cause any issues or hyper pigmentation).

Comes with unused pen needles, even though the 2 cases are open (not touched). Kept sanitary - always stored in a dry cabinet, non smoking home, and kept in the original box it came in (all items it came with come with this item). New pin attachments can be bought inexpensively from Neuderma.
