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.
To be safe I ask my patients to wait about a week before re injection. The reason for this is that hyaluronic acid fillers (like Juvederm and Restylane) often cause some swelling. Even though the hyaluronic acid fillers will be gone within an hour, the swelling may persist. That swelling normally is gone by one week.
