According to DocShop.com on thousands of clinical applications, Restylane related complications have a very low rate of occurrence. Some common, but not severe, Restylane side effects include redness, swelling, tenderness, itching, slight bruising, and other minor discomfort at the injection site, but these side effects tend to disappear within days or hours of the procedure. Additionally, for those receiving Restylane injections in their lips, it is common to experience swelling. Because hyaluronic acid is found naturally in the body, there is little chance of an allergic reaction or of the body rejecting Restylane® injections. Moreover, people with allergies to animal products do not have to worry about Restylane complications due to an allergic reaction and no pre-test is required.
