Is there a way to INCREASE the philtrum to lengthen the upper lip with incompetent lips?

Thank you for your question. It is always helpful to post photos here to provide a recommendation based on your before (or after) photos. Lip augmentation in the form of non-surgical fillers and surgical lip lifting can be an excellent compliment to many plastic surgical procedures. In this way, your surgeon can leverage different options to provide you with a comprehensive treatment plan. I suggest that you move forward and consult with a board certified facial plastic surgeon.
Best wishes,

Yes, this is possible with lip augmentation. Technique will be important here, so you will want someone meticulous. I recommend using cannulas with injections.These fillers, (Volbella, Restylane, Juvederm) are good to create a symmetrical and full lip. Implants or fat are alternative options. See an expert.

Cosmetic fillers, such as hyaluronic acid, including Juvederm or Restylane, can be successfully ininjected in the upper cutaneous lip to accentuate or increase the philtrum column. In some patients, upper lip can be further lengthened with such fillers, but the ultimate decision as to whether such look is truly desirable will be determined during your consultation.
