How Many Botox Units Are Needed for Upper Lip Plumping?

Hello Missnataleigh,
Botox will not help for lip augmentation. We use Restylane or Juvederm in the lips. 
We do use Botox in the upper lip to relax the muscles responsible for contributing to smoker's lines.

Normally an injectable filler like Juvederm or Restylane is used to fill lips as opposed to Botox. Botox is used more for softening vertical lines around the lips or to raise the corners of the lips.

For Botox of the upper lip it will take 2 to 4 units. Your very first time visit at our faclity the Botox is $10.00 per unit. Reg. $13.00 per unit. So for 4 units on your first visit it would be $40.00. 

I agree with most of the others here. Please be cautious of getting Botox into your lips. While some have reported fair results in getting rid of vertical lip lines, there is a significant risk of lip weakness (which is much more unattractive than the lines).
Botox is a great medication when used correctly - but there are likely better choices for lip augmentation.

Botox can be used on the upper lip as a non-approved use for the vertical lines. Botox doesn’t plump the lip. You would need a filler for that. Botox can be used to affect the muscle of the skin-colored upper lip (moustache area, not pink lip) to minimize a “gummy” smile. There are some other unusual techniques as well, but I’m not aware of plumping the lip with Botox.

There is a great misconception that Botox Cosmetic plumps the lips or helps fill out smile lines. This is absolutely false. If there is a doctor or injector telling you this, then do not let them touch you. Botox Cosmetic works by paralyzing the underlying muscles which helps reduce the overlying dynamic lines. There is no volume to Botox. If you are looking for volume, then you need a dermal filler such as Juvederm or Evolence for the smile lines and lips and Radiesse or the cheeks.

Fillers such as Juvederm or Restylane are best to plump lips as they are fillers. Botox, on the other hand, effects the nerve impulses to muscles that create lines or wrinkles (dynamic rhytids). Having said this, I have on occasion injected Botox around the lips for "smoker's lines" and patients have felt that it also helped them achieve a fuller lip by effecting the way the lip roll is.

If you are being treated by a physician who claims that Botox treatments to your lips will result in plumping, please run. Botox will not plump your lips. Plumping or filling of lips can easily be performed safely with a variety of filler materials.
Botox can, however, be used to soften very fine lines around the mouth, but one has to be very conservative with this otherwise significant changes in lip function may result. Usually 2-4 units maximum are used for this purpose in the upper lip and 2-4 maximum in the lower lip. I also tell all of my patient who desire this treatment that they will have certain weaknesses in their lips such as when sucking from a straw or when puckering thie lips as if to give a kiss.
Good luck!

Botox relaxes muscles and is not a filler. It can be used around the lips to soften wrinkles or even curl the corners of the lips up, but if you are interested in fuller lips, I would recommend Juvederm-- I find it works very nicely and evenly in this area.

Botox does not exactly cause lip plumping but my patients do report that they feel that their lips are fuller.
I can only surmise that individuals who typically request Botox for the lips commonly have conditions which cause them to purse their lips which then creates wrinkles or "lipstick bleed lines". They frequently develop a resting tone of pursed lips which can make them small and contracted. Injecting Botox into these individuals causes the muscle to relax and secondarily creates the illusion of a fuller lip. In these instances, I will administer 4-8 units into the upper lip. However, be aware that this will relax the lip and some patients are bothered by this weakness and find it undesireable.
Injecting Botox into a person with a normally relaxed lip may have little if any effect on the shape.
I hope this helps.
