Juvederm
It can take up to two weeks for bruising and swelling to resolve and your final results to be seen from your initial treatment. After that time you can evaluate if you would like further product and it can be injected at that time.
Dear nat744,generally speaking, you can get additional filler when ever you want. If you are considering a treatment, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MDCertified, American Board of Plastic SurgeryMember, American Society of Plastic SurgeryMember, American Society of Aesthetic Plastic Surgery
