Primer (cosmetics)
A cosmetic primer is a cream applied before another cosmetic to improve coverage and lengthen the amount of time the cosmetic lasts on the face. Variations There are different kinds of cosmetic primers, such as foundation primer, eyelid primer, under-eye primer, lip primer, mascara primer, and mattifying primers. A foundation primer may work like a moisturizer, or it may absorb oil with salicylic acid to aid in creating a less oily, more matte appearance. Some contain antioxidants such as A, C, and E, or other ingredients such as grape seed extract and green tea extract. There are water-based and silicon-based foundation primers. Ingredients may include cyclomethicone and dimethicone. Some primers do not contain preservatives, oil or fragrance. Some may also have sun protection factor (SPF). Some foundation primers are tinted to even out or improve skin tone or color. Others give a pearlized finish to make the complexion more light-reflective. There are also foundation prime ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile elastic plates. This characteristic is described as ''perfect basal cleavage''. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, and fillers, especially in parts for automobiles, roofing, and in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost". Properties and structure The mica group comprises 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are translucent to opa ...

Exfoliation (cosmetology)
In cosmetology, exfoliation is the removal of the surface skin cells and built-up dirt from the skin's surface. The term comes from the Latin word ('to strip off leaves'). This is a regular practice within the cosmetic industry, both for its outcome of promoting skin regeneration as well as providing a deep cleanse of the skin barrier. Being used in facials, this process can be achieved by mechanical or chemical means, such as microdermabrasion or chemical peels. Exfoliants are advertised as treatments that enhance beauty and promote a youthful and healthy appearance. History Exfoliation was first practiced among the ancient Egyptians. This was also used in Asia, specifically in China, during the Qing Dynasty (1644–1944). Mechanical exfoliation Mechanical exfoliation methods involve physically scrubbing the skin with an abrasive material. These types of exfoliants include microfiber cloths, adhesive exfoliation sheets, microbead facial scrubs, crêpe paper, crushed ...

Lip Gloss
Lip gloss is a cosmetic used primarily to give lips a glossy luster, and sometimes to add a subtle color. It is distributed as a fluid or a soft solid (not to be confused with lip balm, which generally has medical or soothing purposes, or lipstick, which generally is a solid, cream-like substance that gives off a more pigmented color.) The product is available in ranges of opacity from translucent to solid and can have variously frosted, glittery, glossy, and metallic finishes. Types Like lipstick, lip gloss comes in many forms and may be applied differently. It can be contained in a small cylinder and applied with a rounded or sloped applicator wand (known as a doe foot applicator) or with a built-in lip brush. It can come in a small, soft, squeezable plastic tube designed to be applied directly to the lips or applied with a fingertip or lip brush. Solid or semisolid glosses come in boxes or tubes and sometimes blur the distinction between lip gloss and lip balm. Basic lip ...

Lipstick
Lipstick is a cosmetics, cosmetic product used to apply coloration and texture to lips, often made of wax and oil. Different pigments are used to produce color, and minerals such as silica may be used to provide texture. The use of lipstick dates back to early civilizations such as Sumer and the Indus Valley Civilisation, and was popularized in the Western world in the 16th century. Some lipsticks contain traces of toxic materials, such as lead and PFAS, which prompted health concerns and regulation. Lipstick has been prominent in several women's fashion trends, often associated with women's sexuality. The color of lipstick has aesthetic and cultural significance, as different colors carry different connotations. Red lipstick has historically been associated with sensuality or women's independence, while black lipstick is worn by both men and women in alternative subcultures, especially Punk subculture, punk and Goth subculture, goth. Celebrities such as Marilyn Monroe, Eliza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mascara
Mascara (, ) is a Cosmetics, cosmetic commonly used to enhance the upper and lower eyelashes. It is used to darken, thicken, lengthen, and/or define the eyelashes. Normally in one of three forms—liquid, powder, or cream—the modern mascara product has various formulas; however, most contain the same basic components of pigments, oils, waxes, and preservatives. The most common form of mascara is a liquid in a tube with an application brush. Definition The ''Collins English Dictionary'' defines ''mascara'' as "a cosmetic substance for darkening, lengthening, curling, coloring, and thickening the eyelashes, applied with a brush or rod." The ''Oxford English Dictionary'' (''OED'') adds that mascara is occasionally used on the eyebrows as well. The ''OED'' also references ''mascaro'' from works published in the late 19th century. In 1886, the ''Peck & Snyder Catalogue'' advertises, "Mascaro or Water Cosmetique... For darkening the eyebrow and moustaches without greasing them a ...

Eye Shadow
Eye shadow (or eyeshadow) is a cosmetic applied primarily to the eyelids to attract attention to the wearer's eyes, making them stand out or look more attractive. Eye shadow can also be applied under the eyes, on the cheeks, or to brow bones. Civilizations around the world use and have used eye shadow across genders. In ancient Egypt, it was customarily used by both men and women. Kohl, an ancient eye cosmetic, played a prominent role in various cultures and religious practices. The use of eye shadow attempts to replicate the natural eyelid coloration that some women exhibit due to a natural contrasting pigmentation on their eyelids. Natural eye shadow can range from a glossy shine on one's eyelids to a pinkish tone or even a silver look. Use Eye shadow can add depth and dimension to one's eyes, complement one's eye color, make one's eyes appear larger, or simply draw attention to the eyes. Eye shadow comes in many different colors and textures. It is usually made from a po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eyelid
An eyelid ( ) is a thin fold of skin that covers and protects an eye. The levator palpebrae superioris muscle retracts the eyelid, exposing the cornea to the outside, giving vision. This can be either voluntarily or involuntarily. "Palpebral" (and "blepharal") means relating to the eyelids. Its key function is to regularly spread the tears and other secretions on the eye surface to keep it moist, since the cornea must be continuously moist. They keep the eyes from drying out when asleep. Moreover, the blink reflex protects the eye from foreign bodies. A set of specialized hairs known as lashes grow from the upper and lower eyelid margins to further protect the eye from dust and debris. The appearance of the human upper eyelid often varies between different populations. The prevalence of an epicanthic fold covering the inner corner of the eye account for the majority of East Asian and Southeast Asian populations, and is also found in varying degrees among other populat ...

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , commonly found in nature as quartz. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product. Examples include fused quartz, fumed silica, opal, and aerogels. It is used in structural materials, microelectronics, and as components in the food and pharmaceutical industries. All forms are white or colorless, although impure samples can be colored. Silicon dioxide is a common fundamental constituent of glass. Structure In the majority of silicon dioxides, the silicon atom shows Tetrahedral molecular geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. ...

Sun Protection Factor
Sunscreen, also known as sunblock, sun lotion or sun cream, is a photoprotective topical product for the skin that helps protect against sunburn and prevent skin cancer. Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion), sticks, powders and other topical products. Sunscreens are common supplements to clothing, particularly sunglasses, sunhats and special sun protective clothing, and other forms of photoprotection (such as umbrellas). Sunscreens may be classified according to the type of active ingredient(s) present in the formulation (inorganic compounds or organic molecules) as: * Mineral sunscreens (also referred to as physical), which use only inorganic compounds (zinc oxide and/or titanium dioxide) as active ingredients. These ingredients primarily work by absorbing UV rays but also through reflection and refraction. * Chemical sunscreens, which use organic molecules as active ingredients. These products are sometimes r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moisturizer
A moisturizer, or emollient, is a Cosmetics, cosmetic preparation used for protecting, moisturizing, and lubricating the Human skin, skin. These functions are normally performed by Sebaceous gland, sebum produced by healthy skin. The word "emollient" is derived from the Latin verb ''mollire'', to soften. Mechanism of action In the human body, water constantly evaporates from the deeper layers of the skin through an effect known as transepidermal water loss. By regulating its water content, human skin naturally maintains a dry, easily shed surface as a Innate immune system#Anatomical barriers, barrier against pathogens, dirt, or damage, while protecting itself from drying out and becoming brittle and rigid. The ability to retain moisture depends on the lipid bilayer between the corneocytes, dead skin cells. Moisturizers modify the rate of water loss, with active ingredients of moisturizers falling into one of two categories: occlusives and humectants. ''Occlusives'' form a hydr ...

Dimethicone
Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling. PDMS is particularly known for its unusual rheological (or flow) properties. It is optically clear and, in general, inert, non-toxic, and non-flammable. It is one of several types of silicone oil (polymerized siloxane). The applications of PDMS range from contact lenses and medical devices to elastomers; it is also present in shampoos (as it makes hair shiny and slippery), food (antifoaming agent), caulk, lubricants and heat-resistant tiles. Structure The chemical formula of PDMS is , where ''n'' is the number of repeating monomer units. Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: : + (''n''+1) The polymerization reaction evolves hydrochloric acid.
