Chemical Peel
A chemical peel is a treatment used to improve and smooth the texture of the skin. The skin on the face is most commonly treated, but peels can also be performed on the body. Chemical peels are intended to remove the outermost layers of the skin. To accomplish this task, the chosen peel solution induces a controlled injury to the skin, which causes the skin to peel. This process leads to smoother skin can improve fine lines, acne scars, and pigment. Medium depth peels must be performed by a medical provider (MD, NP, RN, or AP Esthetician in certain states). There are several types of chemical peels. ''α''-hydroxy acid peels Alpha hydroxy acids (AHAs) are naturally occurring carboxylic acids such as glycolic acid, a natural constituent of sugar cane juice, and lactic acid, found in sour milk and tomato juice as well as being produced endogenously during normal metabolism and exercise. This is the mildest of the peel formulas and produces light peels for treatment of fine wr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skin
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/ os clitoris. All mammals have some hair on their skin, even marine mammals like whales, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinoid
The retinoids are a class of chemical compounds that are natural derivatives of vitamin A or are chemically related to it. Synthetic retinoids are utilized in cosmetic formulations, clinical dermatology, and the treatment of some forms of cancer. Retinoids have many important functions throughout the body, including in vision, regulation of skin proliferation and differentiation, growth of bone tissue, immune function, and male fertility. The biology of retinoids is complex, having well-documented effectiveness in the management of conditions ranging from acute promyelocytic leukemia to acne to photoaging. On the other hand, retinoids may be involved in metabolic dysfunction and, at least in some forms, carcinogenesis. Types Retinoids are divided into four generations based on their molecular structure and receptor selectivity. Structure The basic structure of the hydrophobic retinoid molecule consists of a cyclic end group, a polyene side chain and a polar end group. Th ...

Tranquilizer
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or excitement. They are central nervous system (CNS) depressants and interact with brain activity, causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter gamma-aminobutyric acid (GABA). Most sedatives produce relaxing effects by increasing GABA activity. This group is related to hypnotics. The term ''sedative'' describes drugs that serve to calm or relieve anxiety, whereas the term ''hypnotic'' describes drugs whose main purpose is to initiate, sustain, or lengthen sleep. Because these two functions frequently overlap, and because drugs in this class generally produce dose-dependent effects (ranging from anxiolysis to loss of consciousness), they are often referred to collectively as ''sedative–hypnotic'' drugs. Terminology There is some overlap between the terms "sedative" and "hypnotic". Advances in pharmacolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambulatory Surgery Center
Outpatient surgery, also known as ambulatory surgery, day surgery, day case surgery, or same-day surgery, is surgery that does not require an overnight hospital stay.The International Association for Ambulatory Surgery (IAAS) would not consider all of these terms synonymous. In a 2003 documen"Ambulatory (day) surgery: suggested international terminology and definitions" the IAAS recommends defining an "outpatient" procedure as one "carried out in the outpatient department of a hospital" and an "ambulatory" procedure as one "excluding an office/surgery or outpatient operation/procedure, where the patient is discharged on the same working day." That is, "ambulatory surgery" occurs in an "ambulatory surgery center." The term “outpatient” arises from the fact that surgery patients may enter and leave the facility on the same day. The advantages of outpatient surgery over inpatient surgery include greater convenience and reduced costs. Outpatient surgery may occur in an inpatient fa ...

Trichloroacetic Acid
Trichloroacetic acid (TCA; TCAA; also known as trichloroethanoic acid) is an analogue of acetic acid in which the three hydrogen atoms of the methyl group have all been replaced by chlorine atoms. Salts and esters of trichloroacetic acid are called trichloroacetates. Synthesis Trichloroacetic acid was discovered by Jean-Baptiste Dumas in 1830. It is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst such as red phosphorus. This reaction is Hell–Volhard–Zelinsky halogenation. : + 3 → + 3 Another route to trichloroacetic acid is the oxidation of trichloroacetaldehyde. Use It is widely used in biochemistry for the precipitation of macromolecules, such as proteins, DNA, and RNA. TCA and DCA are both used in cosmetic treatments (such as chemical peels and tattoo removal) and as topical medication for chemoablation of warts, including genital warts. It can kill normal cells as well. It is considered safe for use fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solution (chemistry)
In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes. When, as is often but not necessarily the case, the sum of the mole fractions of solutes is small compared with unity, the solution is called a dilute solution. A superscript attached to the ∞ symbol for a property of a solution denotes the property in the limit of infinite dilution." One important parameter of a solution is the concentration, which is a measure of the amount of solute in a given amount of solution or solvent. The term " aqueous solution" is used when one of the solvents is water. Types ''Homogeneous'' means that the components of the mixture form a single phase. ''Heterogeneous'' means that the components of the mixture are of different phase. The properties of the mixture (such as concentration, temp ...

Anesthetic
An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesiology, but others are used commonly in various fields of healthcare. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. Anesthetics are distinct from analgesics, which block only sensation of painful stimuli. Analgesics are typically used in conjunction with anesthetics to control pre-, intra-, and postop ...

Discomfort
Comfort is a state of physical or psychological ease, often characterized by the absence of hardship. Individuals experiencing a lack of comfort are typically described as uncomfortable or in discomfort. A degree of psychological comfort can be achieved by recreating experiences that are associated with pleasant memories, such as engaging in familiar activities, maintaining the presence of familiar objects, and consumption of comfort foods. Comfort is a particular concern in health care, as providing comfort to the sick and injured is one goal of healthcare, and can facilitate recovery.Katharine Kolcaba, Comfort Theory and Practice: A Vision for Holistic Health Care and Research' (2003). . The phrase "comfort zone" is sometimes used to describe a psychological state associated with perceived safety and familiarity. Because of the personal nature of positive associations, psychological comfort is highly subjective. As a verb, "to comfort" generally denotes the act of providing ...

Milium (disease)
A milium (: milia), also called a milk spot or an oil seed, is a clog of the eccrine sweat gland. It is a keratin-filled cyst that may appear just under the epidermis or on the roof of the mouth.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. . Milia are commonly associated with newborn babies, but may appear on people of any age. They are usually found around the nose and eyes, and sometimes on the genitalia, often mistaken by those affected as warts or other sexually transmitted diseases. Milia can also be confused with stubborn whiteheads. In children, milia often disappear within two to four weeks. For adults, they may be removed by a physician (a dermatologist has specialist knowledge in this area). A common method that a dermatologist uses to remove a milium is to nick the skin with a #11 surgical blade and then use a comedone extractor to press the cyst out.

Erythema
Erythema (, ) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. Types * Erythema ab igne * Erythema chronicum migrans * Erythema induratum * Erythema infectiosum (or fifth disease) * Erythema marginatum * Erythema migrans * Erythema multiforme (EM) * Erythema nodosum * Erythema toxicum * Erythema elevatum diutinum * Erythema gyratum repens * Keratolytic winter erythema * Palmar erythema Causes It can be caused by infection, massage, electrical treatment, acne medication, allergies, exercise, solar radiation (sunburn), photosensitization, acute radiation syndrome, mercury toxicity, blister agents, niacin administration, or waxing and tweezing of the hairs—any of which can cause the affected capillaries to dilate, resulting in redness. Erythema is a common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Ritter Von Hebra
Ferdinand Karl Franz Schwarzmann, Ritter von Hebra (7 September 1816 – 5 August 1880) was an Austrian physician and dermatologist known as the founder of the New Vienna School of Dermatology, an important group of physicians who established the foundations of modern dermatology. Life Ferdinand Schwarzmann von Hebra was born in Brno, Moravia, Austrian Empire (in present-day Czech Republic), to a military officer. He first studied in Graz, then entered the University of Vienna and graduated in medicine in 1841. He was influenced by Carl Freiherr von Rokitansky, one of the founders of modern pathological anatomy. Though not its original discoverer, von Hebra's 1844 research dispelled any remaining doubt that the itch mite was the cause of scabies, helping to dispel the humoral theory of skin disease. This publication was the inflection point where the term 'scabies' transitioned from referring to a collection of non-specific itchy ailments, to a particular pathological pr ...

Croton Oil
Croton oil (''Crotonis oleum'') is an oil prepared from the seeds of '' Croton tiglium'', a tree belonging to the order Euphorbiales and family Euphorbiaceae, and native or cultivated in India and the Malay Archipelago. Small doses taken internally cause diarrhea. Externally, the oil can cause irritation and swelling. Croton oil is used in Phenol-croton oil chemical peels for its caustic exfoliating effects it has on the skin. Used in conjunction with phenol solutions, it results in an intense reaction that leads to initial skin sloughing. Since croton oil is very irritating and painful, it is used in laboratory animals to study how pain works, pain-relieving and anti-inflammatory drugs, and immunology. Because croton tiglium oil is cocarcinogenic, it has been used in tumor research. Berenblum and Shubik saw croton oil as a “promoting” agent: a kind of carcinogen that acted through an inflammatory response. Mice painted only with croton oil hadn’t developed tumors. C ...
