Melanin Essays

Melanin is widely dispersed in the animal and plant kingdoms and also synthesized from microorganisms (Riley , 1997). The most common form of biological melanin is eumelanin, a brown-black

Sunlight has UV photons that we humans can’t see but can damage our skin. There are UVB rays and UVA rays, UVB rays are short wavelengths and don’t get deep into our skin so they are the main cause of sunburn + skin cancer but UVA rays have a longer wavelength and go deep into the skin and are the cause of early aging.

By being in the sun my skin was exposed to UV radiation. The melanocytes react to the UV radiation by increasing their activity and increasing the amount of melanin in the keratinocytes. Too much UV radiation

Vitiligo is a skin condition that results in the loss of pigment. Melanocytes, the melanin or pigment producing cells within the body, are destroyed; therefore, preventing the body from making pigment for both the skin and the hair. As a result, skin develops white patches throughout and hair may turn white or gray at an early age. The skin is an integral part of the human body. It is made up of two layers, the epidermis and the dermis. In addition, there are specialized cells within the integumentary

The term dry skin is the expression of the skin that has a rough, dry or scaly appearance with the possible presence of reddening, cracking, or itching [3]. Dry skin can be due to sun damage, immature cells in the surface of the skin as in psoriais or the genetic changes in the desquamation process, as in atopic dermatitis. In all of these cases, a loss of moisture in the surface corneocytes or intercellular lipids results in an outer stratum corneum layer that is mechanically less pliable. Reducing

Vitiligo is a disorder in which there is a disappearance of pigmentation from the skin in white patches. It causes a milk-white appearance that holds no skin pigmentation. This disorder appears on different parts of the body and may affect any age group. In our skin, cells make pigment (color) which determines our tone, these cells are called Melanocytes. Vitiligo destroys melanocytes, therefore, causing the milk-white skin tone. Vitiligo can also affect the mucous membrane, such as the tissues inside

compounds and also react differently than one another. Hair covers nearly every part of our body. In our hair, there are pigments called melanins.
