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.
Patients often ask us how long fillers last. It really depends on which filler is used and where it is injected. For example, hyaluronic fillers such as Restylane, Perlane, Belotero and Juvederm, used to smooth fine lines and wrinkles and create 'poutiness' to the lips typically last 6-9 months.
