A: More than 20 million treatments have been performed since the launch of Restylane in 1996. Product related reactions are rare. There are some injection related reactions which may occur after any injection; they typically resolve spontaneously a few days after injection to the skin, within a week after injection into the lips and within two weeks after injection with Restylane SubQ. These reactions include redness, swelling, pain, itching, bruising or tenderness at the injection site.
After a lip enhancement, your lips may be swollen for up to a week.
In case of more pronounced reactions or if they last longer than a week contact your practitioner.
As with all skin injection procedures there is a small risk of infection. Local inflammatory reactions described as mild to moderate and usually self-limiting within 2 weeks have rarely been reported.
