Can lip lengthening be possible (horizontally) ?

Hi and thank you for your question! In theory we can add more volume and reshape the lips to some degree by skillful injection of hyaluronic acid fillers, and this can increase the length of your lips a little bit. This combined with make-up can help you achieve the look you desire. When it comes to beauty, one of the main factors is the balance between various facial features such as mouth, nose, eyes, cheeks, etc, so a whole-face approach is often the best bet. I hope it helps and good luck!

Thank you for your question. I suggest that you move forward and consult with a board certified facial plastic surgeon to learn more about costs and your candidacy. Cost varies based on local market and surgeon. 
Best wishes,

Thank you for your question.Lip augmentation will help to plump the lips, but does not change the length. You cannot change the anatomy of your lips to lengthen them.

Hi,
Thanks for the question.
Before trying more aggressive stuff, do me a favor and try some Botox around the lips.
Botox will lengthen your lips a bit. It just need very minimal amount with less than $100 cost.
Let's try that out... if that is not enough then consider more aggressive possibilities.
Best of luck :) 

There are no  surgical or non surgical options available to help add length to your lips. Fillers and implants will be able to plump your natural lips but not add length.
