Collagen, and other injectable "fillers" are used to fill in facial defects such as wrinkles and scars, and often to enhance and fill-out other areas such as the lips. It is different than BOTOX® in that it does not inhibit the facial muscles from causing new lines and wrinkles. Whether BOTOX® or Collagen is best suited for the patient is decided during the initial evaluation. Oftentimes a combination of treatments (BOTOX®, Collagen, +/– laser) is most beneficial. Before using Collagen, patients are required to have a Collagen skin test to assure that there will be no allergic reactions to the injection. Like BOTOX®, the process is quick, simple, and effective.
