The procedure devoid of complications has NOT yet been invented and does not exist.
While lip augmentation capabilities have greatly improved in the past 5 years, predictably, permanent lip augmentation has remained stationary for several reasons.
The lip has multiple structural, textural and sensual requirements. An ideal lip filler would have to cause minimal to no lip inflammation and stiffening, create no foreign body sensation in the lip, leave the lip feeling soft and allow it to move without crinkling and folding unnaturally as we animate and move our lips. Finally, it would be great if such an implant aged at the same rate of the lip, changing its shape as the aging lip changes its shape. OBVIOUSLY, such an implant does not exist.
Having been a Plastic surgeon for quite a few years, I have seen implants come and go. They ALWAYS come in with great fanfare, ads in all the ladies journal, well-paid shills both doctors and celebrities touting the newest magical lip plumper - only to slowly retreat into obscurity as newer and better, yet STILL imperfect fillers appear.
For the doubters among you, research the use of paraffin (candle wax) and engine silicone lubricant - both as fillers. The first at the turn of the 20th century. The latter after WWII to die by the late 70's (Only to unfortunately come alive again as "micro droplet technique").
The only kind thing I could advise you if you are intent on putting a permanent implant in your lip is to make sure it can be readily removed. Some present day fillers are firmly distributed within your lip tissues and cannot be totally removed if you do not like the result.
To play it safe, for the time being, go with either Juvederm or Restylane.
