Vitiligo Essay

This treatment can significantly revitalize your skin. This innovative laser resurfacing treatment helps to counteract acne scarring or sun damage. Noticeable results can be obtained in a single treatment. Pixel fractional skin rejuvenation provides dramatic results with the use of superior technology. It involves

Human beings are no exception to biological evolution. Like other organisms around the world, humans have significantly changed overtime and have developed all sorts of diverse characteristics. One noticeable characteristic of human beings is the variation of skin

It develops in the melanocytes, which are cells that produce melanin that gives the skin its pigment or color and protects tissues from ultra violet radiation. Dark skinned people have more melanin than light skinned people do. For this reason, Melanomia is more frequent in light skinned people. (“Detailed description “, 2000, P.2

The basic component in tanning is ultraviolet light. Ultraviolet light, whether produced by a tanning unit or by the sun, contains two components; UVA and UVB. These are the two types of ultraviolet radiation that are known to negatively effect the skin. UVA has a longer wavelength that causes photoaging and can produce some melanomas. UVB has a shorter wavelength that also causes photoaging and has been implicated in skin cancers. Photoaging is the premature aging or deep wrinkling of skin. Indoor tanning units utilize both forms of light waves to tan a person with a minimized risk of sunburn. Tanning outdoors does not give you this option because the sun omits every type of UV rays, so a person is more likely to burn. A person’s skin epidermis consists of two layers: The germinative layer and the horny layer. Another name for the germinative layer is the “living layer.” And another name for the horny layer is the “dead” layer. When exposed to ultraviolet light, melanocytes in the germinative layer produce melanin that is absorbed by surrounding cells. Melanin is a dark pigment found in the pigment-bearing cells of the skin, and melanocytes are epidermal cells capable of synthesizing melanin. This creates a protective barrier from ultraviolet light reaching deeper into the layers of the skin. The pale pink melanin granules are stored in the core of keratin cells. UVA darkens the melanin,

weight loss. Her physician noted small patchy areas of vitiligo and a scaly rash across her nose, cheeks, back,

An example of an area would be in the European areas, where the UV radiation doesn’t beam down as strong onto our skin. If it was another hot open area such as Australia then the skin pigmentation stayed darker. In short, the skin pigmentation adapted to the lifestyle and the surround environment to better help survive in that climate. This is due to the body producing more melanin so the effects of the sun’s rays can be counteracted. Through generations successful genes are passed through the blood line, the human body also has a tendency to produce a particular amount of melanin depending on the location of where one

Vitiligo is a chronic skin disorder that affects the pigmentation of the skin. Pigment is what gives the skin color and is produced by cells called melanocytes. In the disorder, the body attacks the melanocytes resulting in the loss of color in patchy areas. When the color is lost, the affected area becomes a white irregular shaped patch on the outer layer of the skin. Vitiligo can affect a very small portion of the body or affect up to fifty percent of the skin. The most common areas of the body affected by the disorder include the hands, feet, arms, face and sometimes the genitalia. This illness can be treated but it cannot be cured

Melanoma is a malignant condition arising from melanocytes in the basal layer of the skin. Melanocytes are the cells that produce melanin, which gives skin its pigmentation and shields the deeper layers of skin from the damaging effects of ultraviolet radiation. When skin is exposed to ultraviolet radiation, melanocytes increase their production of melanin, which generates darker pigmentation of the skin. Ultraviolet radiation stimulates malignant changes within the melanocytes by mutating DNA, stimulating cutaneous growth factors, decreases immune defenses, and promotes species of melanin that cause DNA impairment and suppress apoptosis. The abnormalities caused by ultraviolet radiation in the melanocytes predispose it to

Idiopathic disorders as Vitiligo may be confused with PA. Vitiligo is an acquired pigmentary disorder of the skin and mucous membranes that is characterized by circumscribed, depigmented

Vitiligo is a continual and long term skin problem that causes white depigmentation on your skin. The white patches appear due to melanocytes within the skin dying off. Melanocytes are cells that reproduce causing pigment, if you lack melanocytes then you will have white patches. Melanin, which gives your skin color also protect you from the sun’s UV rays. Vitiligo affects people differently; there is not an exact place where you can have it. You can have it all over your body, hair, mouth, and even eyes.

Vitiligo is a chronic skin condition where the skin pigment cells (melanocytes) die or, are unable to function to give skin its colour. This inability results in patches of skin looking whiter than the rest of the skin. All skin types can get this condition. It is typically categorized into three main categories: generalized, localized, and segmental

C. Melanoma Skin Cancer is the most dangerous form of skin cancer, it kills one person per hour, these cancerous growths are most often caused by ultraviolet radiation from sunshine or tanning beds. These tumors originate in the pigment-producing melanocytes in the basal layer of the epidermis. Melanoma is caused mainly by intense, occasional UV exposure (frequently leading to sunburn), especially in those who are genetically predisposed to the disease. Often the first sign of melanoma is a change in the size, shape, color or feel of a mole.

A major function of melanin is to act as a defensive barrier of the skin against radiation damage. Ultraviolet light between the wavelengths 280-320nm (UV-B) causes sunburn and damages the skin on nonpigmented peoples. Exposure to this degree of light causes their skin to become dry, leathery, and wrinkled in appearance similar to that associated with aging. This can be seen in Whites living in Australia and South Africa, where ultraviolet light intensity is high because of the relative latitude or closeness to the equator.

Melasma is caused due to an over production of melanin. Melanin is the substance that imparts color to the skin. The exact cause for this type of hyperpigmentation is not known. However, the main four factors that contribute to melasma are hormone, genetics, skin inflammation and sun exposure. Intense exposure to sun can worsen the problem. Pregnancy and menopause also can trigger melasma. It
