1/2 syringe enough to cover gummy smile and uneven upper lip?

Thank you for sharing your question and photograph.  I would recommend only treating your lips with a thicker hyaluronic acid filler like Juvederm Ultra Plus.  Often with lip augmentations the lower border of the upper lip will cover more of the gums and upper teeth of a patient to help improve their smile appearance.  Your smile asymmetry is so subtle I think this is all you will likely need.  Hope this helps.

Thank you for your question. The gummy smile is when the gums are seen while smiling. To correct this you can have a small amount of Botox injected to each side of the nostril to help improve it. Also, a small amount of Botox placed above the upper lip can provide a subtle pout. Fillers, such as Juvederm and Restylane can be used to improve the fullness of the lips. I recommend having a consultation with an expert to discuss your concerns and to determine the best treatment plan for you. Best of Luck!
