I just turned 50 and when I looked in a mirror, the valley created by the 'sunken' skin was all I saw. It was like I had been socked or had just woken up from a 100 years of sleep. After much research on this site and others, I had juvederm injections to make me look human again. The dermatologist was not that keen to do the procedure as she said it can have mixed results, but I wanted to go forward. She suggested a full vial, but I preferred to try the least amount possible. Just a bit of bruising on one eye where the needle went it improperly. Now, after over 2 weeks, results are mixed. I should have had the full vial. Depending on the light, it goes from being a big difference to just a little bit better. Will definitely get again, but with a full vial.
Typically puffiness from a filler lasts no more than one week. An allergy to Juvederm is extremely rare. If you have swelling lasting 2 more weeks ( a total of 6 weeks) I would encourage you to have the area treated with hyaluronidase to remove as much of the product as possible. In regards to the "joker's grin", did you have any neuromuscular block such as Botox or Dysport placed in your lower face? These can sometimes relax the depressor angularis oris - DAO (muscle that pulls the corner of the mouth down) while this usually gives a pleasing subtle lift of the corner, sometimes it can lift too much giving that "joker" appearance. If you had no neuromuscular blocks placed at the DAO, I'm wondering if you had nerve blocks or some irritation of the nerve in that area of the jaw, this would usually resolve with time. In regards to broken capillaries occuring on the skin after filler, this is not routinely seen but can occur anytime an individual has swelling as you have. These vessels can be readily treated with the VBeam laser, but may resolve with time and may be improved with topical anti-inflammatory products. Even over the counter products such as a Nia product might be helpful. Gentle prescription products that help with vessels include: Finacea, and possibly Epiceram. Hope this information is helpful.
