Although modern makeup has been traditionally used mainly by women, men also use makeup to enhance their own facial features or cover blemishes and dark circles.

Cosmetics brands have increasingly targeted men in the sale of cosmetics, with some products targeted specifically at men.


Types

Though there are a large number of differing cosmetics used for a variety of different purposes, all cosmetics are typically intended to be applied externally. These products can be applied to the face (on the skin, lips, eyebrows and eyes), to the body (on the skin, in particular the hands and nails), and to the hair. These products may be intended for use as skincare, personal care or to alter the appearance, with the subset of cosmetics known as makeup primarily referring to products containing colour pigments intended for the purpose of altering the wearer's appearance; some manufacturers will distinguish only between "decorative" cosmetics intended to alter the appearance and "care" cosmetics designed for skincare and personal care. Most cosmetics are also distinguished by the area of the body intended for application, with cosmetics designed to be used on the face and eye area usually applied with a brush, a makeup sponge, or the fingertips. Cosmetics can be also described by the physical composition of the product. Cosmetics can be liquid or cream

Decorative

* Primers are used on the face before makeup is applied, creating a typically transparent, smooth layer over the top of the skin, allowing for makeup to be applied smoothly and evenly. Some primers may also be tinted, and this tint may match the wearer's skin tone, or may colour correct it, using greens, oranges and purples to even out the wearer's skin tone and correct redness, purple shadows or orange discolouration respectively. *
Concealer A concealer or color corrector is a type of cosmetic that is used to mask imperfections on the skin. These imperfections can include dark circles under the eyes, blemishes, and hyperpigmentation. Concealer is similar to, and can be used in conjun ...
is a cream or liquid product used to conceal marks or blemishes of the skin. Concealer is typically the colour of the user's skin tone, and is generally applied after the face has been primed to even out the wearer's skin tone before foundation can be applied. Concealer is usually more heavily pigmented, higher coverage and thicker than foundation or tinted primers. Though concealer is often more heavy duty in terms of pigment and consistency than foundation, a number of different formulations intended for different styles of use - such as a lighter concealer for the eyes and a heavier concealer for stage makeup - are available, as well as colour correcting concealers intended to balance out discolouration of the skin specifically. * Foundation is a cream, liquid, mousse or powder product applied to the entirety of the face to create a smooth and even base in the user's skin tone. Foundation provides a generally lower amount of coverage than concealer, and is sold in formulations that can provide sheer, matte, dewy or full coverage to the skin. * Rouge , blush, or blusher is a liquid, cream or powder product applied to the centre of the cheeks with the intention of adding or enhancing their natural colour. Blushers are typically available in shades of pink or warm tan and brown, and may also be used to make the cheekbones appear more defined. *

is a powder, cream or liquid product that adds colour to the skin, typically in bronze or tan shades intended to give the skin a tanned appearance and enhance the colour of the face. Bronzer, like highlighter, may also contain substances providing a shimmer or glitter effect, and comes in either matte, semi-matte, satin, or shimmer finishes. * Highlighter is a liquid, cream or powder product applied to the high points of the face such as the eyebrows, nose and cheekbones. Highlighter commonly has substances added providing a shimmer or glitter effect. Alternatively, a lighter toned foundation or concealer can be used as a highlighter. *

is a powder, cream or liquid pigmented product used to draw attention to, accentuate and change the shape of the area around the eyes, on the eyelid and the space below the eyebrows. Eyeshadow is typically applied using an eyeshadow brush, with generally small and rounded bristles, though liquid and cream formulations may also be applied with the fingers. Eyeshadow is available in almost every colour, as well as being sold in a number of different finishes, ranging from matte finishes with sheer coverage to glossy, shimmery, glittery and highly pigmented finishes. Many different colours and finishes of eyeshadow may be combined in one look and blended together to achieve different effects. * Eyeliner is used to enhance and elongate the apparent size or depth of the eye; though eyeliner is commonly black, it can come in many different colours, including brown, white and blue. Eyeliner can come in the form of a pencil, a gel or a liquid. * False eyelashes are used to extend, exaggerate and add volume to the eyelashes. Consisting generally of a small strip to which hair - either human, mink or synthetic - is attached, false eyelashes are typically applied to the lash line using glue, which can come in latex and latex free varieties; magnetic false eyelashes, which attach to the eyelid after magnetic eyeliner is applied, are also available. Designs vary in length and colour, with rhinestones, gems, feathers and lace available as false eyelash designs. False eyelashes are not permanent, and can be easily taken off with the fingers. Eyelash extensions are a more permanent way to achieve this look. Each set lasts for two to three weeks, then the set can be filled, similar to the maintenance of acrylic nails. To apply to extensions the certified lash artist would start by taping down the bottom eyelashes. The lash artist would then use two tweezers, one to isolate the natural eyelash and one to apply the false eyelash. An individual false eyelash, or lash fan, is applied to one natural eyelash using a lash glue specific for this process. The eyelashes should not be stuck together. The length and thickness of the false lash should not be to heavy for the natural eyelash. If this process is done correctly no harm will be done to the natural eyelashes. *

Other styles of lip colouration products such as lip stains temporarily saturate the lips with a dye, and typically do not alter the texture of the lips. Both lip colour products and lip liners may be waterproof, and may be applied directly to the lips, with a brush, or with the fingers. Lip balms, though designed to moisturise and protect the lips (such as through the addition of UV protection) may also tint the lips. *

Skincare

Cleansing is a standard step in skin care routines. Skin cleansing includes some or all of these steps or cosmetics: * Cleansers or foaming washes are used to remove excess dirt, oil, and makeup left on the skin. Different cleansing products are aimed at various types of skin, such as sulfate-free cleansers and spin brushes. ** Cleansing oil or oil cleanser is an oil-based solution that gently emulsifies the skin's natural oils and removes makeup. Cleansing oils are typically used as part of a two-step cleansing process. After the skin has been cleansed with an oil cleanser, a second cleanse is done using a mild gel, milk or cream cleanser to ensure any traces of the oil cleanser and makeup are removed. * Toners are used after cleansing to remove any remaining traces of cleanser and restore the pH of the skin. They also may add some hydration. They are usually applied to a cotton pad and wiped over the skin, but can be sprayed onto the skin from a spray bottle or poured onto the hand and patted directly onto the skin. Toners usually contain water, citric acid, herbal extracts and other ingredients. Witch hazel is still commonly used in toners to tighten the pores and refresh the skin. Alcohol is used less often as it is drying and can be irritating to the skin. It may still be found in toners specially for those with oily skin. Some toners contain active ingredients and target particular skin types, such as tea tree oil,

, or glycolic acid. * Hyperpigmentation treatment: Kojic Acid soap, cream or powder and Arbutin (b-D-glucopyranoside derivative of hydroquinone) serum or cream helps to get rid of hyperpigmentation spots of the skin. * Facial masks are treatments applied to the skin and then removed. Typically, they are applied to a dry, cleansed face, avoiding the eyes and lips. ** Clay-based masks use kaolin clay or fuller's earth to transport essential oils and chemicals to the skin, and are typically left on until completely dry. As the clay dries, it absorbs excess oil and dirt from the surface of the skin and may help to clear blocked pores or draw comedones to the surface. Because of its drying actions, clay-based masks should only be used on oily skins. ** Peel masks are typically gel-like in consistency and contain acids or exfoliating agents to help exfoliate the skin, along with other ingredients to hydrate, discourage wrinkles, or treat uneven skin tone. They are left on to dry and then gently peeled off. They should be avoided by people with dry or sensitive skin, as they tend to be very drying. ** Sheet masks are a relatively new product that are becoming extremely popular in Asia. Sheet masks consist of a thin cotton or fiber sheet with holes cut out for the eyes and lips and cut to fit the contours of the face, onto which serums and skin treatments are brushed in a thin layer; the sheets may be soaked in the treatment. Masks are available to suit almost all skin types and skin complaints. Sheet masks are quicker, less messy, and require no specialized knowledge or equipment for their use compared to other types of face masks, but they may be difficult to find and purchase outside Asia. ** Exfoliants are products that help slough off dead skin cells from the topmost layer of the skin to improve the appearance of the skin. This is achieved either by using mild acids or other chemicals to loosen old skin cells or lightly abrasive substances to physically remove them. Exfoliation can also help even out patches of rough skin, improve cell turnover, clear blocked pores to discourage acne, and improve the appearance and healing of scars. ** Chemical exfoliants include azelaic acid, citric acid, acetic acid, malic acid, mandelic acid, glycolic acid, lactic acid, salicylic acid, papain and bromelain. They may be found in cleansers, scrubs and peels, but also leave-on products such as toners, serums and moisturisers. Chemical exfoliants mainly fall into the categories of AHAs, BHAs, PHAs or enzymes. ** Abrasive exfoliants include gels, creams or lotions, as well as physical objects. *

Sunscreens are marked with 'spf' which means 'sun protection factor' this shows that a product provides protection against UVB. UVA ratings on sunscreens can be denoted by the amount of stars or plus symbols varying amongst countries. It is to be noted UVA ratings do not specifically depict the amount of UVA protection a sunscreen is providing but rather the ratio of equal UVA and UVB protection. The recommended 'gold standard' of a sunscreen should be at least SPF 30 and at least 4 stars or plus symbols. Daily sunscreen application is very important but uses of shade, clothing, and hats are as important and more effective for sun protection.

Using the appropriate brush to apply a certain product allows the product to blend into the skin smoothly and evenly. * A foundation brush is usually a dense brush that distributes the product evenly while smoothing out the face. This brush is best used to achieve full coverage. * A

This brush is best used to achieve light to medium coverage. * A blush brush comes in all shapes and sizes and is used to apply blush, allowing the blush to look natural while giving a flush of color. * A powder brush tends to be big and fluffy for quick and easy application of dusting powder all over the face. Powder gives the appearance of a matte effect. * A bronzer blush, which can also serve as a contour brush is an angled brush that gives the face dimensions and illusions, by allowing the makeup to be placed in substitution of bone structure. This brush can also be used to add a shimmering highlight illusion to the cheekbones, nose and chin. * A highlight brush, also known as a fan brush, has bristles that are typically spread out and is used to apply where the sun would naturally hit. * An

is a popular applicator. Makeup sponges can be used to apply foundation, blend concealer, and apply powder or highlighter. Loofahs, microfiber cloths, natural sponges, or brushes may be used to exfoliate skin, simply by rubbing them over the face in a circular motion. Gels, creams, or lotions may contain an acid to encourage dead skin cells to loosen, and an abrasive such as microbeads, sea salt and sugar, ground nut shells, rice bran, or ground apricot kernels to scrub the dead cells off the skin. Salt and sugar scrubs tend to be the harshest, while scrubs containing beads or rice bran are typically very gentle.

s. Lipsticks, liquid foundations, and other liquid cosmetics, as well as compressed makeups such as eye shadow and blush in compacts, are often called mineral makeup if they have the same primary ingredients as dry mineral makeups. Liquid makeups must contain preservatives and compressed makeups must contain binders, which dry mineral makeups do not. Mineral makeup usually does not contain synthetic fragrances, preservatives, parabens, mineral oil, and chemical dyes. For this reason, dermatologists may consider mineral makeup to be gentler to the skin than makeup that contains those ingredients. Some minerals are nacreous or pearlescent, giving the skin a shining or sparking appearance. One example is bismuth oxychloride. There are various mineral-based makeup brands, including: Bare Minerals, Tarte, Bobbi Brown, and Stila.


Porous minerals

Porous minerals is a subcategory of mineral makeup ingredients where the porosity of the mineral particles enables extraordinary absorption capacity compared to non-porous mineral materials. This feature improves sebum control, long-lasting mattifying effect or gives a matte texture when used in makeup. Porous minerals can also act as carriers, absorbing a wide range of substances into its porous network.


Advertised benefits of mineral-based makeup

Although some ingredients in cosmetics may cause concerns, some are seen as beneficial. Titanium dioxide, found in sunscreens, and zinc oxide have anti-inflammatory properties. Many mineral based makeup create a barrier between the skin and outside elements, which allows it to provide some protection against the sun and its possible harmful effects. Mineral makeup is noncomedogenic (as long as it does not contain talc) and offers a mild amount of sun protection (because of the titanium dioxide and zinc oxide).


Packaging

The term cosmetic packaging is used for primary packaging and secondary packaging of cosmetic products. Primary packaging, also called cosmetic container, is housing the cosmetic product. It is in direct contact with the cosmetic product. Secondary packaging is the outer wrapping of one or several cosmetic container(s). An important difference between primary and secondary packaging is that any information that is necessary to clarify the safety of the product must appear on the primary package. Otherwise, much of the required information can appear on just the secondary packaging. Cosmetic packaging is standardized by the ISO 22715, set by the

Controversy

During the 20th century, the popularity of cosmetics increased rapidly. Cosmetics are used by girls at increasingly young ages, especially in the United States. Because of the fast-decreasing age of makeup users, many companies, from high-street brands like Rimmel to higher-end products like Estee Lauder, cater to this expanding market by introducing flavored lipsticks and glosses, cosmetics packaged in glittery and sparkly packaging, and marketing and advertising using young

Safety

In the United States: "Under the law, cosmetic products and ingredients do not need FDA premarket approval." The EU and other regulatory agencies around the world have more stringent regulations. The FDA does not have to approve or review cosmetics, or what goes in them, before they are sold to the consumers. The FDA only regulates against some colors that can be used in the cosmetics and hair dyes. The cosmetic companies do not have to report any injuries from the products; they also only have voluntary recalls of products. There has been a marketing trend towards the sale of cosmetics lacking controversial ingredients, especially those derived from

light), and mutagenicity. Due to the ethical concerns around animal testing, some nations have legislated against animal testing for cosmetics. An updated list can be found on the Humane Societies website. According to the Humane Society of the United States, there are nearly 50 non-animal tests that have been validated for use, with many more in development, that may replace animal testing and are potentially more efficacious. In the United States, mice, rats, rabbits, and cats are the most used animals for testing. In 2018, California banned the sale of animal tested cosmetics. Cosmetics testing is banned in the Netherlands, India, Norway, Israel, New Zealand, Belgium, and the UK, and in 2002, the European Union agreed to phase in a near-total ban on the sale of animal-tested cosmetics throughout the EU from 2009, and to ban all cosmetics-related animal testing. In December 2009, the European Parliament and Council passed the

, a bill to regulate the cosmetic industry in the EU. EC Regulation 1223/2009 took effect on July 11, 2013. In March 2013, the EU banned the import and sale of cosmetics containing ingredients tested on animals. China required animal testing on cosmetic products until 2014, when they waived animal testing requirements for domestically produced products. In 2019, China approved nine non-animal testing methods, and announced that by 2020 laws making animal testing compulsory would be lifted. In June 2017, legislation was proposed in Australia to end animal testing in the cosmetics industry. In March 2019, the Australian Senate passed a bill banning the use of data from animal testing in the cosmetic industry after July 1, 2020.


Legislation


Europe

In the European Union, the manufacture, labelling, and supply of cosmetics and personal care products are regulated by Regulation EC 1223/2009. It applies to all the countries of the EU as well as Iceland, Norway, and Switzerland. This regulation applies to single-person companies making or importing just one product as well as to large multinationals. Manufacturers and importers of cosmetic products must comply with the applicable regulations in order to sell their products in the EU. In this industry, it is common fall back on a suitably qualified person, such as an independent third party inspection and testing company, to verify the cosmetics' compliance with the requirements of applicable cosmetic regulations and other relevant legislation, including

The current law on cosmetics in the U.S. does not require cosmetic products and ingredients to have FDA approval before going on the market except from color additives. The Cosmetic Safety Enhancement Act was introduced in December 2019 by Representative Frank Pallone.

(ISO) published new guidelines on the safe manufacturing of cosmetic products under a Good Manufacturing Practices (GMP) regime. Regulators in several countries and regions have adopted this standard, ISO 22716:2007, effectively replacing existing guidance and standards. ISO 22716 provides a comprehensive approach for a quality management system for those engaged in the manufacturing, packaging, testing, storage, and transportation of cosmetic end products. The standard deals with all aspects of the supply chain, from the early delivery of raw materials and components until the shipment of the final product to the consumer. The standard is based on other quality management systems, ensuring smooth integration with such systems as ISO 9001 or the British Retail Consortium (BRC) standard for consumer products. Therefore, it combines the benefits of GMP, linking cosmetic product safety with overall business improvement tools that enable organisations to meet global consumer demand for cosmetic product safety certification.ISO 22716

In July 2012, since microbial contamination is one of the greatest concerns regarding the quality of cosmetic products, the ISO has introduced a new standard for evaluating the antimicrobial protection of a cosmetic product by preservation efficacy testing and microbiological risk assessment.
