Radiesse is a great filler for the nasolabial grooves.
Radiesse lasts about 1 yr and is a great filler for the creases by the nose. cost is roughly $650/syringe and easy to undergo. Artefill is a good choice as well and is a permanent filler which lasts about 4-5 yrs at a cost of $1000 per syringe. Sincerely, David Hansen,MD
