The first thing you should expect after a Juvederm treatment is for the treated area to be swollen. Don’t be alarmed if your lips look larger than you anticipated. It can take up to 14 days for the swelling to subside and for you to see the final results of your new perfected pout. Also, some patients have the habit of touching their lips or cheeks afterwards and are alarmed when they feel lumps and bumps. While some of the lumpiness will smooth out over time, you may always feel small differences and this is normal. The important aspect is how the area looks, visually, not how it feels. As with any injection, you may experience some bruising or redness around the injection sites. You can expect side effects with Juvederm Ultra XC and Ultra Plus XC up to 14 days and side effects with Juvederm Voluma can up to four weeks. Think of it this way: since results with Juvederm Voluma last the longest (up to two years), the side effects can take the longest to subside.
