Restylane is an excellent hyaluronic acid product. In Canada, they have recently introduced the restylane and perlane (thicker version of restylane, longer-lasting) mixed with a small amount of local anesthetic. This makes the procedures less traumatic to our patients and minimize any larger bruising seen with the traditional dental blocks. Juvederm is an excellent alternative, which also comes mixed with local anesthetic, and is available in Toronto Canada.
The real question to ask is "what are your goals with fillers?". Restylane is a hyaluronic acid (HA) filler which is very appropriate for lip augmentation and perioral line filling. Juvederm is another HA filler which works very well for this purpose. If your concerns relate to Nasolabial folds and/or facial volume, a more durable filler/volumizer like Radiesse or Sculptra should be considered.
