So using the static keyword will make your code a bit faster since no object creation is involved. An important point to note is that a static class in C# is different from one in Java. In Java, the static modifier is used to make a member class a nested top level class inside a package.
Lip augmentation may be performed from several minimally invasive techniques. First, dermal fillers are useful for temporary enhancement for approximately 8-12 months. Normally recovery will take 1-2 weeks from the dermal injectable fillers. The fillers may include collagen (Zyderm or Zyplast), Radiance, Juvaderm, and Restylane. AlloDerm, Fascia, Autologen, and dermal grafts may induce swelling for up to 2 weeks.
In general, fillers (Hyaluronic Acids) last from 6 months to a year. How long fillers last depends on: 1) the amount injected, 2) the location of placement and 3) the number of repeated injections. Placement in areas of motion (nasolabial folds and lips) cause the filler to dissipate more rapidly; whereas, injection in the tear trough region tends to be apparent longer.
