I was treated yesterday with this device. The doctor told me that it was Secret RF but it doesn't look like the machines I have seen pictures of online. I also found what looks like the same device on a Chinese wholesale site for only $1000. Would a machine like this even have disposable needle tips? The doctor told me he was using a fresh disposable cartridge. I am worried I have been treated with one of these non-FDA approved devices - what should I do? Thank you.
