Cosmetology
Cosmetology (from Greek , ''kosmētikos'', "beautifying"; and , '' -logia'') is the study and application of beauty treatment. Branches of specialty include hairstyling, skin care, cosmetics, manicures/ pedicures, non-permanent hair removal such as waxing and sugaring, and permanent hair removal processes such as electrology and intense pulsed light (IPL). In the United States as of 2018, an occupational license is required in all states to be a cosmetologist, with the average cost of a certificate from a for-profit school being $17,000 and 1,500 required hours, (ten times the hours required for an EMT), with cosmetologists making a median wage of $25,000. Cosmetology specialties Cosmetologist Cosmetologists are trained and licensed to perform cosmetic treatments to the hair, skin, and nails. This can be expanded into multiple parts including cutting and chemically treating hair, chemical hair removal, fashion trends, wigs, nails and skin care, skin and hair analysis; ...

Cosmetic Electrotherapy
Cosmetic electrotherapy is a range of beauty treatments that uses low electric currents passed through the skin to produce several therapeutic effects such as muscle toning in the body and micro-lifting of the face.Dawn Mernagh-Ward, Jennifer Cartwright, ''Health and beauty therapy: a practical approach for NVQ level 3'', Edition 3, Publisher Nelson Thornes, 2004, , . 420 pagespage 109 It is based on electrotherapy, which has been researched and accepted in the field of rehabilitation, though the "scientific and medical communities have tended to sideline or dismiss the use of electrotherapy for healthy muscles". The use of electricity in cosmetics goes back to the end of the 19th century, almost a hundred years after Luigi Galvani discovered that electricity can make the muscle in a frog's leg twitch (see galvanism). Subsequent research in electrophysiology has been carried out by people such as Robert O. Becker, Dr Björn Nordenström, a former chair of the Nobel Selection C ...

Cosmetics
Cosmetics are constituted mixtures of chemical compounds derived from either natural sources, or synthetically created ones. Cosmetics have various purposes. Those designed for personal care and skin care can be used to cleanse or protect the body or skin. Cosmetics designed to enhance or alter one's appearance (makeup) can be used to conceal blemishes, enhance one's natural features (such as the eyebrows and eyelashes), add color to a person's face, or change the appearance of the face entirely to resemble a different person, creature or object. Cosmetics can also be designed to add fragrance to the body. Definition and etymology The word ''cosmetics'' derives from the Greek (), meaning "technique of dress and ornament", from (), "skilled in ordering or arranging" and that from (), meaning "order" and "ornament". Cosmetics are constituted from a mixture of chemical compounds derived from either natural sources, or synthetically created ones. Legal definition ...

Pedicure
A pedicure is a cosmetic treatment of the feet and toenails, analogous to a manicure. Pedicures include care not only for the toenails; dead skin cells are rubbed off the bottom of the feet using a rough stone (often a pumice stone). Skincare is often provided up to the knee, including granular exfoliation, moisturizing, and massage. The word ''pedicure'' is derived from the Latin words '' pedis'', which means "of the foot", and ''cura'', which means "care". History People have been pedicuring their nails for more than 4,000 years. In southern Babylonia, noblemen used solid gold tools to give themselves manicures and pedicures. The use of fingernail polish can be traced back even further. Originating in China in 3000 BC, nail colour indicated one’s social status, according to a Ming Dynasty manuscript; royal fingernails were painted black and red. Ancient Egyptians have been manicuring all the way back to 2300 BC. A depiction of early manicures and pedicures was foun ...

Microdermabrasion
Dermabrasion is a type of surgical skin planing, generally with the goal of removing acne, scarring and other skin or tissue irregularities, typically performed in a professional medical setting by a dermatologist or plastic surgeon trained specifically in this procedure. Dermabrasion has been practiced for many years (before the advent of lasers) and involves the controlled deeper abrasion (wearing away) of the upper to mid layers of the skin with any variety of strong abrasive devices including a wire brush, diamond wheel or fraise, sterilized sandpaper, salt crystals or other mechanical means. Dermabrasion should not be confused with microdermabrasion which is a newer and non-surgical cosmetic procedure performed by non-physician personnel, nurses, aestheticians and medical assistants. Dermabrasion procedures are surgical, invasive procedures that typically require a local anaesthetic. Often, they are performed in surgical suites or in professional medical centers. Since the ...

Hairstyle
A hairstyle, hairdo, haircut or coiffure refers to the styling of hair, usually on the human scalp. Sometimes, this could also mean an editing of facial or body hair. The fashioning of hair can be considered an aspect of personal grooming, fashion, and cosmetics, although practical, cultural, and popular considerations also influence some hairstyles. The oldest known depiction of hair styling is hair braiding which dates back about 30,000 years. In history, women's hair was often elaborately and carefully dressed in special ways, though it was also often kept covered outside the home, especially for married women. From the time of the Roman Empire until the Middle Ages, most women grew their hair as long as it would naturally grow. Between the late 15th century and the 16th century, a very high hairline on the forehead was considered attractive. Around the same period, European men often wore their hair cropped no longer than shoulder-length. In the early 17th century, m ...

Dibutyl Phthalate
Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C6H4(CO2C4H9)2, it is a colorless oil, although commercial samples are often yellow.Peter M. Lorz, Friedrich K. Towae, Walter Enke, Rudolf Jäckh, Naresh Bhargava, Wolfgang Hillesheim "Phthalic Acid and Derivatives" in Ullmann's Encyclopedia of Industrial Chemistry, 2007, Wiley-VCH, Weinheim. Production and use DBP is produced by the reaction of ''n''-butanol with phthalic anhydride. DBP is an important plasticizer that enhances the utility of some major engineering plastics, such as PVC. Such modified PVC is widely used in plumbing for carrying sewerage and other corrosive materials. Degradation Hydrolysis of DBP leads to phthalic acid and 1-butanol. Monobutyl phthalate (MBP) is its major metabolite. Biodegradation Biodegradation by microorganisms represents one route for remediation of DBP. For example, ''Enter ...

Toluene
Toluene (), also known as toluol (), is a substituted aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent. As the solvent in some types of paint thinner, permanent markers, contact cement and certain types of glue, toluene is sometimes used as a recreational inhalant and has the potential of causing severe neurological harm. History The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it ''rétinnaphte''. In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree '' Myroxylon balsamum''), which Deville recognized as simil ...

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (U ...

Acne Vulgaris
Acne, also known as ''acne vulgaris'', is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide. Susceptibility to acne is primarily genetic in 80% of cases. The roles of diet and cigarette smoking in the condition are unclear, and neither cleanliness nor exposure to sunlight appear to play a part. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum. Another common factor is the excessive growth of the bacterium ''Cutibacterium acnes'', which is present on the skin. Treatments for acne are ...

Dermatologist
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία ''-logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.
