I've been using Juvederm for the last 6 years to fill in the nasolabial folds. I had moderate lines, about 2cm long, only slightly deep, so not too bad. Since using Juvederm, they've disappeared. I am 43 years old, and am now at the point of considering it for cheeks and on the chin.
After my first Juvederm, I needed a top up after 6 months. Third time it was something like 8, then 9, etc.. my last top-up was 12 months ago and I think I can easily wait another 3-4 months.
I take Juvederm that has anesthetic, it hurts only a little, while the other one was very painful.
