Yes, this is normal. Lips can take up to 2 weeks to settle. Give it time and reassess. Sometimes arnica can help - occasionally premedications BEFORE filling such as antihistamines or predinisione can reduce future swelling. Physicians often prescribe these pre-meds to reduce the chances of swelling in the future. All the best, Dr Isobel Walker. Fiori Institute. Brisbane. Australia.
1.6 ml of juvederm is a bit high for the first treatment but you still have a nice result and I'm sure that over the next couple of weeks the swelling that you're feeling and tightness will dissipate. Good luck from New York City
