Anal bleaching is the process of lightening the color of the skin around the anus. It is done for cosmetic purposes, to make the color of the anus more uniform with the surrounding area. Some treatments are applied in an office or salon by a cosmetic technician and others are sold as cream that can be applied at home.
Pornographic film actresses were the first to undergo the anal bleaching process, in an effort to lighten the color of their anuses to match the rest of their skin. [1] As Brazilian waxing became popular, due to the popularity of smaller swimsuits and lingerie, the spread of pornography into the mainstream, and endorsement of the procedure by celebrities, [2] women began noticing that their anuses were darker than the rest of their skin. [1] The increase in the number of women engaging in anal sex has also contributed to women's concern over the appearance of their anuses. [1] As a result of this perceived problem, anal bleaching began to gain appeal. [3] Some gay men also make use of the procedure. [4] [5]
The treatment was first offered in the US in California in 2005; it was reported to be available at the same time in Australia. [5] Spas outside of Hollywood were slow to begin offering it as a beauty treatment, with just one New York spa offering the service by 2007. [6] Creams are now sold for use at home. [7] Although the popularity of anal bleaching has not approached that of Brazilian waxing, it received mainstream recognition in the US in the 2010s.
There are several methods to carry out the anal lightening process. The most common method is to simply use an at-home lotion or gel to target the darkened anal and genital area and gradually fade the darkened area over time.
Many early cosmetics designed for anal bleaching contained ingredients that would irritate the sensitive anal area, creating temporary discomfort and even burning, scarring, or incontinence. [7] However, modern products are more likely to be designed with sensitive skin in mind, and are aimed at producing lightening effects without irritation.
The process performed with creams containing hydroquinone is banned in some countries, such as the member states of the EU. [8] In 2006, the FDA removed previous advice that stated hydroquinone was considered generally safe, as hydroquinone has been linked to ochronosis, where skin becomes permanently discoloured and disfigured, and because it may also be a carcinogen. [9] All over-the-counter (OTC) sales over hydroquinone were banned in the US with the CARES Act of 2020 and a prescription is now required for purchase. [10]
Other principal ingredients that are used in skin lightening cosmetics are arbutin and kojic acid. [8] Arbutin, often also called bearberry, can be converted by the body into hydroquinone. [11]
Kojic acid was developed as a safer alternative to hydroquinone, however it is less effective at lightening and also carcinogenic. [12]
Azelaic acid is another option.
Mercury was commonly used as a skin lightening agent. However, due to the known hazards of mercury (renal damage, neurotoxicity, anxiety and depression), [13] [14] the FDA has prohibited mercury in cosmetic products since 1974, [15] except for trace amount below 1 ppm (21CFR'700.13).
The procedure was briefly shown in 2004 in an episode of Cosmetic Surgery Live . [16] One salon that performed the procedure received an increase in queries in 2005 attributed to an episode of Dr. 90210 on E!, when porn star Tabitha Stevens was filmed having her anus bleached. [5]
Cosmetics are composed of mixtures of chemical compounds derived from either natural sources or synthetically created ones. Cosmetics have various purposes, including personal and skin care. They can also be used to conceal blemishes and enhance natural features. Makeup can also add colour to a person's face, or change the appearance of the face entirely to resemble a different person, creature, or object.
Hair coloring, or hair dyeing, is the practice of changing the color of the hair on humans' heads. The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a color to suit preference or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching.
Clobetasol propionate is a corticosteroid used to treat skin conditions such as eczema, contact dermatitis, seborrheic dermatitis, and psoriasis. It is applied to the skin as a cream, ointment, or shampoo. Use should be short term and only if other weaker corticosteroids are not effective. Use is not recommended in rosacea or perioral dermatitis.
Hyperpigmentation is the darkening of an area of skin or nails caused by increased melanin.
Periorbital dark circles are dark blemishes around the eyes. There are many causes of this symptom, including heredity and bruising.
Melasma is a tan or dark skin discoloration. Melasma is thought to be caused by sun exposure, genetic predisposition, hormone changes, and skin irritation. Although it can affect anyone, it is particularly common in women, especially pregnant women and those who are taking oral or patch contraceptives or hormone replacement therapy medications.
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also referred to as hydroquinones. The name "hydroquinone" was coined by Friedrich Wöhler in 1843.
Ochronosis is a syndrome caused by the accumulation of homogentisic acid in connective tissues. The condition was named after the yellowish (ocher-like) discoloration of the tissue seen on microscopic examination. Macroscopically, though, the affected tissues appear bluish-grey because of a light-scattering phenomenon known as the Tyndall effect. The condition is most often associated with alkaptonuria, but can occur from exogenous administration of phenol complexes such as hydroquinone. It was first described by Rudolf Virchow in 1865.
Natural skin care uses topical creams and lotions made of ingredients available in nature. Much of the recent literature reviews plant-derived ingredients, which may include herbs, roots, flowers and essential oils, but natural substances in skin care products include animal-derived products such as beeswax, and minerals. These substances may be combined with various carrier agents, preservatives, surfactants, humectants and emulsifiers.
A lentigo is a small pigmented spot on the skin with a clearly defined edge, surrounded by normal-appearing skin. It is a harmless (benign) hyperplasia of melanocytes which is linear in its spread. This means the hyperplasia of melanocytes is restricted to the cell layer directly above the basement membrane of the epidermis where melanocytes normally reside. This is in contrast to the "nests" of multi-layer melanocytes found in moles. Because of this characteristic feature, the adjective "lentiginous" is used to describe other skin lesions that similarly proliferate linearly within the basal cell layer.
Skin whitening, also known as skin lightening and skin bleaching, is the practice of using chemical substances in an attempt to lighten the skin or provide an even skin color by reducing the melanin concentration in the skin. Several chemicals have been shown to be effective in skin whitening, while some have proven to be toxic or have questionable safety profiles. This includes mercury compounds which may cause neurological problems and kidney problems.
Kojic acid is an organic compound with the formula HOCH2C5H2O2OH. It is a derivative of 4-pyrone that functions in nature as a chelation agent produced by several species of fungi, especially Aspergillus oryzae, which has the Japanese common name koji. Kojic acid is a by-product in the fermentation process of malting rice, for use in the manufacturing of sake, the Japanese rice wine. It is a mild inhibitor of the formation of pigment in plant and animal tissues, and is used in food and cosmetics to preserve or change colors of substances. It forms a bright red complex with ferric ions.
beta-Arbutin, also known as β-arbutin or by its International Nomenclature of Cosmetic Ingredients (INCI) name, arbutin, is a glycosylated derivative of hydroquinone. β-Arbutin is naturally present in the leaves and bark of a variety of plants, notably the bearberry plant, Arctostaphylos uva-ursi. Utilized as a biosynthetic active ingredient in topical treatments for skin lightening, β-arbutin is aimed at addressing hyperpigmentation issues. Its mechanism of action involves inhibiting the activity of tyrosinase, an essential enzyme for melanin synthesis in the human skin, thereby leading to a reduction in hyperpigmentation. It is important to distinguish β-arbutin from its structurally similar stereoisomer, α-arbutin, which exhibits similar effects in clinical applications.
The history of cosmetics spans at least 7,000 years and is present in almost every society on earth. Cosmetic body art is argued to have been the earliest form of a ritual in human culture. The evidence for this comes in the form of utilised red mineral pigments including crayons associated with the emergence of Homo sapiens in Africa. Cosmetics are mentioned in the Old Testament—2 Kings 9:30 where Jezebel painted her eyelids—approximately 840 BC—and the book of Esther describes various beauty treatments as well.
Bihaku is a Japanese term coined in the 1990s with the emergence of skin whitening products and cosmetics.
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO3. Sodium bisulfite in fact is not a real compound, but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions. It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide. Regardless of its ill-defined nature, sodium bisulfite is used in many different industries such as a food additive with E number E222 in the food industry, a reducing agent in the cosmetic industry, and a decomposer of residual hypochlorite used in the bleaching industry.
The cosmetic industry describes the industry that manufactures and distributes cosmetic products. These include colour cosmetics, like foundation and mascara, skincare such as moisturisers and cleansers, haircare such as shampoos, conditioners and hair colours, and toiletries such as bubble bath and soap. The manufacturing industry is dominated by a small number of multinational corporations that originated in the early 20th century, but the distribution and sale of cosmetics is spread among a wide range of different businesses. Cosmetics must be safe when customers use them in accordance with the label's instructions or in the conventional or expected manner. One measure a producer may take to guarantee the safety of a cosmetic product is product testing. FDA occasionally does testing as part of its research program or when looking into potential safety issues with a product. Both the cosmetics business and consumers can benefit from the FDA's resources on product testing.
alpha-Arbutin, or α-arbutin, is a glycosylated hydroquinone, and an anomer of the naturally occurring arbutin. α-Arbutin is used in the cosmetic and pharmaceutical industries for its skin lightening effects, treatment of hyperpigmentation, and as a safer alternative to hydroquinone.
Cetyl tranexamate mesylate is a bioavailable derivative of tranexamic acid for use in cosmetic formulations. Its primary use is in skincare products aimed at enhancing appearance by targeting hyperpigmentation, uneven skin tone, inflammation, dark spots, UV induced erythema, acne scars, and overall skin clarity.
