It has been 5 months and I am pleased to say the results have stayed the same! I have heard Juvederm can last a year, so I am optimistic. I purchased 2 syringes, one for each side. There was a little left over after injecting the right side, so my doctor (a dermatologist) injected some into the "cupids bow" of my upper lip. I am also happy with those results. It wasn't painful (I had numbing cream applied 30 min. prior). I did have a little swelling, but ice packs helped a lot. I also had 2 small bruises, but they disappeared after 3 days. I recommend getting this procedure on a Friday morning (if you can take the day off from work) so you have the weekend to recover.
I was so happy with the results, I went back a month later and had Botox injected for $300 into my frown lines ("elevens" - AKA glabellar lines) between my eyes. I am glad my doctor didn't over inject the site, as I was worried about getting a droopy eye. (A good friend had this happen at one of those medi-spas that have coupon discounts, so I was cautious). Again, I am very pleased with the results. It has been 4 months and I have noticed that the Botox is wearing off and my frown lines are coming back. I will probably go back in 2 months to have it redone. If so, I will update my experience with the Juvederm Ultra.
I would definitely recommend this procedure, but make sure you do your research and find a doctor with the proper experience to do it.
