Thank you for your question. Both Volbella and Restylane Silk are used to treat rhytids and creases around the lips (ie. "smoker's lines"), and both yield great results. Personally, I've noticed that Restylane Silk tends to swell a little more initially, but Volbella takes a little longer to settle into the skin tissue. As for longevity, one is not better than the other. For periorbital lines, I suggest trying Botox initially, and determine whether that is enough to soften the lines to your liking. If creases are deeper than what Botox can correct, consider resurfacing modalities for a more corrective treatment, or dermal filler for temporary resolution of the creases. Best of luck!
