Same Size for Both Lips During Augmentation?

As already correctly noted, the upper lip is generally smaller than the lower.  For purposes of augmentation, this relationship should be preserved.  However, there are anatomic variants and at times, the upper lip may be at least equal in size to the lower.  If the patient so desires, this ratio can be maintained during the procedure.  Generally speaking, making a small upper lip larger than the lower lip is less aesthetically appealing.

Lips need to be balanced. The key is to think about not just the size of the lips, but also their position relative to the rest of the face.
As we age, our upper lips get longer in addition to thinner. You need to think about this as getting the upper teeth to show a bit either with a lip lift or with a filler can help you get the results you really want.
It can also be a good idea to bring in a picture of lips you find attractive. While you can't necessarily get that look exactly, your facial plastic surgeon can speak with you about the characteristics you like and work with you towards an excellent outcome.

Hi,

Most experienced injectors preserve and enhance your normal anatomy which is a proportion or 30-40% upper lip to 70-60% lower lip.  That being said, each person's lips in relationship to other aspects of their face especially the lips and nose are different.  I often hear of patients saying that they unlike unnaturally full upper and lower lips.  It is best to bring in pictures of lips that you like that fit your facial structure and ask your provider if that is possible to achieve in your face.  During the process of augmentation, have the provider show you what they have done so far to see if it is close to achieving the look you want.  Always remember, less is more.  You can always do more later after you get used to your new look.
