Will lip injections change the shape of my lips?

Filler would give you a fuller pout but not change the shape of your lips, seek a reputable physician who can provide a result you wish to achieve 

If your injections are performed properly by a very experienced injector, no. Lip filler should add volume without changing the nice shape of your lips. This is not the case if you choose an injector without an aesthetic eye. Most plastic surgeon and dermatologist injectors will be able to create a fuller but still beautifully shaped lip for you.I hope this information is helpful.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Your lips have a very nice shape. Restyling injections properly done should enhance the appearance of your lips and not distort them. Typically fillers can be used to balance shape and size of the Lips so you should have a good discussion with your doctor about what you want before the injections. If you want to maintain a certain appearance to the Cupid's Bow and upper lip that should be easily accomplished. Also think about the size proportions for your lips- whether you want the upper lip fuller than the lower lip, vice versa or the same in size- as this can be changed if you want or you can leave them in a proportion similar to what they are now.

Having the lips injected when you already have a beautiful shaped lip should be easy with a skilled injector.  Please find a board certified Dermatologist with a great deal of experience in cosmetics for the best results.

It depends what you want and the skill of the injector. Patients like you that have nicely shaped lips and just desire a bigger version of what they have can be enhanced without changing the shape.  Shaping can be done with very thin lips by injecting behind the muscle, flap lips can be made more round, lack of definition under the nose can be created by injecting the columns, the cupid's bow can be accentuated, as can the tubercle in the upper middle lip. Some lower lips look better with injections of the middle third, others need selective volumization at the corner thirds. There is definitely an art to lip injections...
