Both these injectables are hyaluronic acids. They are injected into the skin to smoothen out wrinkles. Common areas treated are the nasolabial lines (the lines lateral to the nostrils and above the lips), marionette lines, and cheek lines. The lips can also be augmented or plumped up. These injections are generally done under local anesthetic block to minimize the discomfort of the injection. The effects last about 6 months, though sometimes longer by my clinical observations. If you are getting your lips treated and have a history of cold sores of the lips, you will need to be treated with anti-viral medications before and after treatment. The charge for the injectables is by the number of syringes used or requested. Expect some bruising and swelling after injection.
