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.
the science of clinically using hyaluronidase is still being worked out. How long it lasts is questionable. I would wait at least a week if not a month before injecting more filler to even it out. Otherwise, injecting the new filler in an area injected with hyaluronidase too soon, may produce more thinning than desired of the new filler.
