  • Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). Following initial infection, a person may not notice any symptoms or may experience a brief period of influenza-like illness.  Typically, this is followed by a prolonged period with no symptoms.  As the infection progresses, it interferes more with the immune system, increasing the risk of common infections like tuberculosis, as well as other opportunistic infections, and tumors that rarely affect people who have working immune systems. These late symptoms of infection are referred to as AIDS. This stage is often also associated with weight loss.

 Injectable filler (injectable cosmetic filler, injectable facial filler)

  • Soft tissue filler injected into the skin to help fill in facial wrinkles, restoring a smoother appearance. Most of these wrinkle fillers are temporary because they are eventually absorbed by the body.

It usually has a smooth top and a pink or purple color. Keloids are irregularly shaped and tend to enlarge progressively. Unlike scars, keloids do not regress over time.
