Cleanser
The term cleanser refers to a product that cleans or removes dirt or other substances. A cleanser could be a detergent, and there are many types of cleansers that are produced with a specific objective or focus. For instance, a degreaser or carburetor cleanser used in automotive mechanics for cleaning certain engine and car parts. Other varieties include the ones used in cosmetology, dermatology or general skin care. In this case, a cleanser is a facial care product that is used to remove make-up, skin care product residue, microbes, dead skin cells, oils, sweat, dirt and other types of daily pollutants from the face. These washing aids help prevent filth-accumulation, infections, clogged pores, irritation and cosmetic issues like dullness from dead skin buildup and excessive skin shine from sebum buildup. This can also aid in preventing or treating certain skin conditions, such as acne. Cleansing is the first step in a skin care regimen and can be used in addition of a toner ...

Make-up
Cosmetics are substances that are intended for application to the body for cleansing, beautifying, promoting attractiveness, or altering appearance. They are mixtures of chemical compounds derived from either natural sources or created synthetically. Cosmetics have various purposes, including personal and skin care. They can also be used to conceal blemishes and enhance natural features (such as the eyebrows and eyelashes). Makeup can also add colour to a person's face, enhance a person's features or change the appearance of the face entirely to resemble a different person, creature, or object. People have used cosmetics for thousands of years for skin care and appearance enhancement. Visible cosmetics for both women and men have gone in and out of fashion over the centuries. Some early forms of cosmetics contained harmful ingredients such as lead that caused serious health problems and sometimes resulted in death. Modern commercial cosmetics are generally tested for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skin Care
Skin care or skincare is the practice of maintaining and improving the health and appearance of the skin. It includes washing, moisturizing, protecting from the sun, and treating skin problems like acne and dryness. Skin care can help prevent infections and irritation and is an important part of daily hygiene. Skin care is at the interface of cosmetics and dermatology. Skin care differs from dermatology by its inclusion of non-physician professionals, such as estheticians and nursing staff. Skin care includes modifications of individual behavior and of environmental and working conditions. Skin care is an essential part of wound healing, radiation therapy, and the management of some medications. General care The skin is the largest organ in the human body. It protects against germs, dirt, and harmful substances. Simple habits like washing and applying lotion can make a big difference in skin health, but little is known scientifically about the benefits and clinical effica ...

Acne
Acne ( ), also known as ''acne vulgaris'', is a long-term Cutaneous condition, skin condition that occurs when Keratinocyte, dead skin cells and Sebum, oil from the skin clog hair follicles. Typical features of the condition include comedo, blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of sebaceous gland, oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to lack of confidence, anxiety (mood), anxiety, reduced self-esteem, and, in extreme cases, clinical depression, depression or suicidal ideations, 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 hygiene, cleanliness nor exposure to sunlight are associated with acne. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Cream
Cold cream, also known as ''ceratum refrigerans'', is an emulsion of water and certain fats, usually including beeswax and various scent agents, designed to smooth skin and remove makeup. Cold cream is a water-in-oil emulsion (emulsion of small amount of water in a larger amount of oil), unlike the oil-in-water emulsion of vanishing cream, so-called because it seems to disappear when applied on skin. The name "cold cream" derives from the cooling feeling that the cream leaves on the skin. Variations of the product have been used for nearly 2000 years. Cold cream is mainly used for skin treatment (such as a facial mask or lip balm), due to its moisturizing properties. It can also be used as shaving cream and as a makeup remover. History The invention of cold cream is credited to Galen, a physician in second century Greece. The original formulation involved rose water, beeswax, and either almond or olive oil. The beeswax is essential to a successful cream, as it is the emuls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In cosmetics, skin toner or simply toner refers to a water-based lotion, Herbal tonic, tonic, or wash designed to cleanse the skin and prepare it for other skincare products, such as moisturizers and serums. Typically used on the face, toners remove any remaining impurities after cleansing, balance the skin’s pH, and hydrate the skin. They also serve to protect and refresh the skin, often containing ingredients that can soothe, moisturize, exfoliate, or target specific skin concerns like oil control or pore minimization. Toners are typically categorized by their function and intensity into types such as skin bracers, tonics, acid toners, and astringents.

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 ...

Sebaceous Glands
A sebaceous gland or oil gland is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet. In the eyelids, meibomian glands, also called tarsal glands, are a type of sebaceous gland that secrete a special type of sebum into tears. Surrounding the female nipples, areolar glands are specialized sebaceous glands for lubricating the nipples. Fordyce spots are benign, visible, sebaceous glands found usually on the lips, gums and inner cheeks, and genitals. Structure Location In humans, sebaceous glands are found throughout all areas of the skin, except the palms of the hands and soles of the feet. There are two types of sebaceous glands: those connected to hair follicles and those that exist indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Detergent
A detergent is a surfactant or a mixture of surfactants with Cleanliness, cleansing properties when in Concentration, dilute Solution (chemistry), solutions. There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ions found in hard water. Definitions The word ''detergent'' is derived from the Latin adjective , from the verb , meaning to wipe or polish off. Detergent can be defined as a surfactant or a mixture of surfactants with cleansing properties when in Concentration, dilute Solution (chemistry), solutions. However, conventionally, detergent is used to mean synthetic cleaning compounds as opposed to ''soap'' (a salt of the natural fatty acid), even though soap is also a detergent in the true sense.

Soap
Soap is a salt (chemistry), salt of a fatty acid (sometimes other carboxylic acids) used for cleaning and lubricating products as well as other applications. In a domestic setting, soaps, specifically "toilet soaps", are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, emulsifiers, and catalysts. Soaps are often produced by mixing fats and oils with a Base (chemistry), base. Humans have used soap for millennia; evidence exists for the production of soap-like materials in ancient Babylon around 2800 BC. Types Toilet soaps In a domestic setting, "soap" usually refers to what is technically called a toilet soap, used for household and personal cleaning. Toilet soaps are salts of fatty acids with the general formula (Carboxylate ion, RCO2−)M+, where M is Sodium, Na (sodium) or Potassium, K (potassium).
