Both Perlane and Juvederm are great choices for treating the nasolabial folds. They are both hyaluronic acids that last long, are very forgiving, and can be reversed if necessary. Their use in different areas is largely up to the preference of the practitioner and patient. However, there are some very important distinctions:
Juvederm is probably better than Perlane for treating the lips as it has a silky almost liquid-like consistency.
However, this same silkiness makes Juvederm not as suitable as Perlane for under the eyes, because it has a tendency to collect fluid and cause edema under the eyes.
Both Juvederm and Perlane are great for non-surgical rhinoplasty.
They are both great for the nasolabial folds, although I think it's much more important to treat the cheeks primarily than to treat the nasolabial folds. When done correctly, treating the cheeks will support the eyes, and lift the cheeks, also improving the nasolabial folds.
Perlane and Juvederm both last about a year in all, however most of my patients are seen at 6 months, when half of the effects have faded.
In summary, they are both great products doing great things! Good luck!
