Can lip augmentation reduce my philtrum length?

Thanks for your question. Without any photos it's difficult to give an exact recommendation. However, strategically  placed filler, containing hyaluronic acids such as Juvederm, Restylane, and Volbella, can create fuller volume in the lips. Indeed, it can even suddenly change the shape of the lip as well. However, if you have significant lip shape issues, such as a long upper lip or drooping corners, then you could opt for other procedures, such as an upper or corner lip lift, in order for you to achieve your ideal lip shape. Additional options also include fat grafting or implants. Best to consult with a board certified physician in order to achieve best individual results.

Thank you for sharing your question.  Though fillers will not physically change the distance if placed correctly they will camouflage the 15mm to make the distance appear smaller. Hope this helps.
