FaceTite is primarily used for the lower face and neck. It can be used in the midface to help tighten this area as well. I would not recommend it for the upper eyelids. The skin is very thin and the risk of causing a burn is higher. There are great surgical and nonsurgical options(laser resurfacing) that you can consider to tighten and remove excess skin. Hope this helps.
There are much better options for the upper eyelids. FaceTite combined with miniliposuction is best for the mid and lower face. The thicker tissues allow more delivery of the radiofrequency wavelength energy to treat multiple levels.
