Permalip implants - two implants in the same lip?

 Hi, I have performed many lip augmentation procedures using dermal fillers or lip implants for over 30 years.  Non smiling photos of your lips would help in the evaluation.   The upper lip should be approximately 75 % the size of the lower lip for the lips to appear balanced. The lips can be augmented using a dermal filler or a Permalip implant.
Dermal filers and lip implants offer a much more reliable volume for augmentation of the lips than permanent fillers or fat injections which are associated with increased, unwanted, side effects.
 Implants are typically not "stacked" as they can't be secured to one another.  There's also the issue of overwhelming the existing lip tissue that would result in extrusion of the implant.  In other words, there is a finite amount of implant volume that can and should be placed in each lip.  10mm's of anything would far exceed that ability in my humble opinion.  For additional lip volume, following Perma lip implant placement, your best course of action is to have the lips filled with an off the shelf dermal filler.  Whatever volume is derived from the implants is a permanent enhancement which is the main benefit of having lip augmentation with implants versus dermal fillers.  That however doesn't mean that there's an unlimited degree of augmentation, to the lips, that an implant can or should provide.
Hope this helps.
