After receiving injections of Perlane or Restylane in Toronto, you might have some swelling, redness, pain, bruising, and tenderness. This normally lasts less than seven days. Although rare, red or swollen small bumps may occur. If you have had facial cold sores before, an injection can cause another outbreak. In extremely rare circumstances, the nurse may inject into a blood vessel, which could damage the skin. To avoid bruising or bleeding, you should not use Restylane if you have recently used drugs that thin your blood or prevent clotting. If you are pregnant, breastfeeding, or under the age of 18, you should not use Restylane or Perlane.

Restylane and Perlane should not be used by people with previous bad allergies, particularly to certain microorganisms known as gram positive bacteria, by people with previous bad allergies to drugs that have required in-hospital treatment, or by people with bleeding disorders. Restylane and Perlane should not be injected anywhere except the skin or just under the skin.

The use of Restylane and Perlane at the site of skin sores, pimples, rashes, hives, cysts, or infection should be postponed until healing is complete. Use of Restylane and Perlane in these instances could delay healing or make your skin problems worse.
