Restylane
Restylane is the trade name for a range of injectable fillers with a specific formulation of non-animal sourced hyaluronic acid (HA). In the United States, Restylane was the first hyaluronic acid filler to be approved by the U.S. Food and Drug Administration (FDA) for cosmetic injection into subdermal facial tissues. Restylane is produced by Galderma. Medical uses Restylane is most commonly used for lip enhancement (volume and contouring). It is used to diminish wrinkles and aging lines of the face such as the nasolabial folds (nose to mouth lines) and melomental folds (sad mouth corners). It may also be used for filling aging-related facial hollows and "orbital troughs" (under and around the eyes), as well as for cheek volume and contouring of the chin, lips and nose. Side effects A treatment with a dermal filler like Restylane can cause some temporary bruising in addition to swelling and numbness for a few days. In rare cases there has been reports of lumps or granulomas. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lip Enhancement
Lip augmentation is a cosmetic procedure that modifies the shape of the lips using fillers, such as collagen or implants. The procedure may be performed to increase lip size, correct asymmetry, create protrusion, or adjust the ratio of the top and bottom lips. The procedure typically involves surgical injection, though temporary non-surgical alternatives exist. Swelling and bruising are common after lip augmentation, and irritation or allergic reaction may also occur. Lip augmentations can have undesired cosmetic effects, including scarring and lumping, and implants pose the risk of shifting underneath the lip or breaking through the skin. History Around 1900, surgeons tried injecting paraffin into the lips without success. Liquid silicone was used for lip augmentation, starting in the early 1960s but was abandoned thirty years later due to fears about the effects of silicone on general health and long term aesthetic outcome. About 1980, injectable bovine collagen was introd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injectable Filler
Injectable filler (injectable cosmetic filler, injectable facial filler) is a soft tissue filler injected into the skin at different depths to help fill in facial wrinkles, provide facial volume, and augment facial features: restoring a smoother appearance. Most of these wrinkle fillers are temporary because they are eventually absorbed by the body. Most dermal fillers today consist of hyaluronic acid, a naturally occurring polysaccharide that is present in skin and cartilage. Some people may need more than one injection to achieve the wrinkle-smoothing effect. The effect lasts for about six months or longer. Successful results depend on health of the skin, skill of the health care provider, and type of filler used. Regardless of material (whether synthetic or organic) filler duration is highly dependent on amount of activity in the region where it is injected. Exercise and high intensity activities such as manual labor can stimulate blood flow and shorten the lifespan of fillers. ...

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 virule ...

Food And Drug Administration (United States)
The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), but the agency also enforces other laws, notably Section 361 of the Public Health Service Act, as well as associated regulations. Much of this regulatory-enforcement work is not directly related to food or drugs, but involves such things as regulating lasers, cellular phones, and condoms, as well as control of disease in contexts varying fro ...

Wrinkles
A wrinkle, also known as a rhytid, is a fold, ridge or crease in an otherwise smooth surface, such as on skin or fabric. Skin wrinkles typically appear as a result of ageing processes such as glycation, habitual sleeping positions, loss of body mass, sun damage, or temporarily, as the result of prolonged immersion in water. Age wrinkling in the skin is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors. In humans, it can also be prevented to some degree by avoiding excessive solar exposure and through diet (in particular through consumption of carotenoids, tocopherols and flavonoids, vitamins (A, C, D and E), essential omega-3-fatty acids, certain proteins and lactobacilli). Skin Causes for aging wrinkles Development of facial wrinkles is a kind of fibrosis of the skin. Misrepair-accumulation aging theory suggests that wrinkles develop from incorrect repairs of injured elastic fibers and collagen fibers. Repea ...

Nasolabial Fold
The nasolabial folds, commonly known as "smile lines" or "laugh lines", are facial features. They are the two skin folds that run from each side of the nose (human), nose to the corners of the mouth (human), mouth. They are defined by facial structures that support the buccal fat pad. They separate the cheeks from the upper lip. The term derives from Latin language, Latin '':wikt:nasus#Latin, nasus'' for "nose" and '':wikt:labium#Latin, labium'' for "lip". Nasolabial fold is a misnomer, however. The proper anatomical term is melolabial fold, meaning the fold between the cheek and lip. Cosmetology issues With ageing the fold may grow in length and depth. Injectable filler, Dermal fillings may be used to replace lost fats and collagen in this facial area. Facial exercises give effective results in erasing the appearance of nasolabial folds. See also *Epicanthal fold *Nasalis muscle References Facial features Cosmetics Skin anatomy {{anatomy-stub ...

Hyaluronidase
Hyaluronidases are a family of enzymes that catalyse the degradation of hyaluronic acid (HA). Karl Meyer classified these enzymes in 1971, into three distinct groups, a scheme based on the enzyme reaction products. The three main types of hyaluronidases are two classes of eukaryotic endoglycosidase hydrolases and a prokaryotic lyase-type of glycosidase. In humans, there are five functional hyaluronidases: HYAL1, HYAL2, HYAL3, HYAL4 and HYAL5 (also known as SPAM1 or PH-20); plus a pseudogene, HYAL6 (also known as HYALP1). The genes for HYAL1-3 are clustered in chromosome 3, while HYAL4-6 are clustered in chromosome 7. HYAL1 and HYAL2 are the major hyaluronidases in most tissues. GPI-anchored HYAL2 is responsible for cleaving high-molecular weight HA, which is mostly bound to the CD44 receptor. The resulting HA fragments of variable size are then further hydrolized by HYAL1 after being internalized into endo-lysosomes; this generates HA oligosaccharides. According to their en ...

Glycosaminoglycans
Glycosaminoglycans (GAGs) or mucopolysaccharides are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a galactose unit. GAGs are found in vertebrates, invertebrates and bacteria. Because GAGs are highly polar molecules and attract water; the body uses them as lubricants or shock absorbers. Mucopolysaccharidoses are a group of metabolic disorders in which abnormal accumulations of glycosaminoglycans occur due to enzyme deficiencies. Production Glycosaminoglycans vary greatly in molecular mass, disaccharide structure, and sulfation. This is because GAG synthesis is not template driven, as are proteins or nucleic acids, but constantly altered by processing enzymes. GAGs are classified into four groups, based on their core disaccharide structures. Hepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
