Which one is better Facetite or Accutite? And how much does it cost?

Hi There glnjln! 
Depends on what areas you want treated or what results you're looking for. 
Let me start by telling you about each and how they differ, then you can see which fits you best. 
I would also recommend finding a specialist you trust and having a thorough conversation about your expectations and what your options are. 
Accutite and Facetite are both members of the BodyTite® Radiofrequency-assisted liposuction (RFAL) family from Inmode. They both are used to reduce wrinkles, folds and sagging areas of the face without the need for general anesthesia, sedation, incisions or downtime.
Facetite is designed specifically for the face, neck, jawline and other small areas of the body. It is a safe and effective non-invasive contouring procedure that replaces a traditional Facelift. Facetite is also useful as an enhancement to liposuction when cement-like fibrofatty tissue needs to be treated.
Facetite can be used to treat:
Sagging jaw line – a.k.a. The jowlsDouble chins and neck areaOther small areas of the body
Accutite is designed for smaller areas of the face and body that require more specific attention. Truly that is the only difference in the two. Accutite can even be used in replacement of a Labiaplasty. 
Accutite is recommended to treat: 
The brow lineThe periorbital region – The area around the eyesNasolabial folds – a.k.a. Parentheses line around the nose and mouthVulva 
Hope this helps! Best of Luck
