Non-surgical Rhinoplasty
Non-surgical rhinoplasty is a medical aesthetic procedure in which injectable fillers, most commonly hyaluronic acid ones like Restylane and Juvederm or calcium hydroxyapatite (Radiesse), are used to alter and shape a person's nose without a surgery. The procedure fills in depressed areas on the nose, lifting the angle of the tip or smoothing the appearance of bumps on the bridge. Non surgical rhinoplasty is an augmentation procedure, so it cannot reduce the size of someone's nose. The cosmetic procedure carries the risk of causing serious skin damage or distant complications like blindness. If the filler product is injected into an artery, filler can travel in the arteries and blocks smaller size arteries like ophthalmic artery and cause blindness. If blood vessels of the skin is blocked, skin necrosis can develop. Hyaluronic acid based fillers can be reversed even if injected into a blood vessel with an enzyme called hyaluronidase, which can be also injected like fillers. Origina ...

Hyaluronic Acid
Hyaluronic acid (; abbreviated HA; conjugate base hyaluronate), also called hyaluronan, is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is unique among glycosaminoglycans as it is non-sulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large: human synovial HA averages about 7 million Da per molecule, or about 20,000 disaccharide monomers, while other sources mention 3–4 million Da. The average 70 kg (150 lb) person has roughly 15 grams of hyaluronan in the body, one-third of which is turned over (i.e., degraded and synthesized) per day. As one of the chief components of the extracellular matrix, it contributes significantly to cell proliferation and migration, and is involved in the progression of many malignant tumors. Hyaluronic acid is also a component of the group A streptococcal extracellular capsule, and is believed to play a role in virul ...
