Lip injections for African American woman?

Thank you for sharing your question and photographs.  Well placed hyaluronic acid based dermal fillers - Juvederm Vollure, Restylane Defyne - can improve upon your lip volume while smiling as well as narrow the asymmetries between your lips.  Be sure to see an ASPS board certified plastic surgeon in consultation to maximize your results.  

Thank you for your question. Yes, fillers can create a more symmetrical lip and improve your lip when you smile. I suggest that you consult with your board certified facial plastic surgeon to determine your candidacy.
Best wishes,

The hyaluronic-acid based dermal fillers, such as Juvederm, Restylane Silk, and Volbella can help you achieve the symmetry and volume you desire. Depending on where you want the most volume and where the least, you could sculpt your upper lip by layering different fillers, as they have different properties. Volbella and Restylane Silk are best for restoring symmetry and making subtle changes. Juvederm adds more dramatic volume. Consulting with a board-certified dermatologist will let you achieve the look you want.
