What's the best lip injection technique?

Lip injections can be performed to either restore the appearance of lips which have changed over time or 2 enhance the appearance of lips by making them a bit more full.  These goals are separate and distinct.  Injection of lips is something of an art.   When performed well the results are spectacularly.  I would recommend a finding an injector in your area who has an outstanding reputation for performing lip injections.  I would not micro-manage the injector by telling them exactly which technique they should use to treat you.

The lips should be viewed in balance wth the other facial features. Treatment goals can be very different depending on the age of the person and their goals. Reestablishing volume and definition in an older person is different from enhancing features in a younger person. The proper balance and proportion should also be maintained between the upper and lower lip. Ultimately it comes down to the aesthetic vision of the injector and experience in making the desired changes.  Sometimes the lip border needs definition and enhancement. Other times the lips need volume and fulness. The right product should also be selected. Anticipated swelling needs to be considered. Sometimes it is better to recheck and touch up areas after a couple  weeks when swelling has resolved.

You are correct that the exact technique of lip injection varies significantly from one physician to the next.  I agree with you that injecting the actual lip generally gives a more natural result, but sometimes injections in the vermillion can accentuate the lips in a natural and attractive way as well.  Good luck!

this is something that you need to have a consult with the doctor.  some people do injections, silicon, or lip implants. your doctor should know which option is best for you.

When you consider augmenting the lip, you really need to consider the entire lip and the surrounding area. Often it's not just the lip itself that needs to be filled, but the surrounding area that serves as structural support.If you have little volume loss in the lip body, you can sometimes get away with a small enhancement of the border and philtral column, but usually you'll need some additional fill to evert the lip so it's not tucked under - as happens often as you age.The goal is to stay natural looking and true to your own facial proportions. There are effective ways to enhance the appearance of your lips without sacrificing natural movement or projection.Downturned corners can be lifted with Botox or filler - this one step can make a big difference in how the size of your lips is perceived.We have to remember that the face is a compilation of many muscles, fat compartments and a complicated and ever-changing skeletal support so it's often not the best idea to try to select a single feature to change.
