The line running from the nose to the upper lip is also known as the nasolabial fold. With time, this line can become deeper and more apparent - this is due to gradual volume loss on the face due to the natural aging process. Dysport will not be effective at treating the nasolabial folds - these are better addressed with fillers, such as Voluma, Restylane, Restylane Lyft, Juvederm, etc. Neuromodulators like Dysport and Botox are used to treat lines and wrinkles created by repeated muscle movement. They can be used in the lower face, to address issues like a gummy smile, downturned lips, or to contour the jawline and reduce teeth grinding. That said, I typically recommend against using Dysport in these areas, as it tends to spread more than Botox and can affect other muscles in the area, causing facial asymmetry. Botox injections are fairly complex - I would recommend seeking a consultation with a board-certified dermatologist or plastic surgeon with extensive experience in Botox injections.
