Dermal fillers such as Juvederm and Restylane are widely used to restore volume and enhance facial features, and while generally very safe, it’s important to be aware of potential side effects and how to care for your skin after treatment. Some people may experience mild swelling, redness, tenderness, or bruising around the injection site. These effects are temporary and usually settle within a few days, although in some cases they may last up to 10 days. Lip treatments in particular can cause more noticeable swelling for 24–72 hours, so it’s best to avoid planning big social events immediately after your appointment. If you have a history of cold sores, dermal fillers can sometimes trigger a recurrence, so keeping prescribed antiviral medication on hand is advised. Treatments are not recommended during pregnancy or while breastfeeding, as their safety has not been established. To help minimise bruising and swelling, you may be advised to avoid certain medications such as aspirin or ibuprofen in the week leading up to and shortly after your treatment. It’s also best to avoid Vitamin E supplements or St. John’s Wort for a few days, and to skip strenuous exercise for 24 hours. Some clients also take arnica tablets before their appointment to support the healing process. With the right preparation and aftercare, dermal fillers deliver natural-looking results safely and effectively, leaving you with a refreshed and rejuvenated appearance.
