Melanin is produced in specialized cells called melanocytes, but these do not behave in the same way for all people. Some people naturally produce less melanin, which means less pigment and lighter skin. Other people possess fewer melanocytes than normal, which also results in less overall pigment...
Melanoma,the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its color. Melanoma can also form in your eyes and, rarely, inside your body, such as in your nose or throat. What are the 5 warning signs of mel...
Melanoma is a type of skin cancer that originates from the melanocytes. Melanocytes are cells that produce melanin. In the skin, melanocytes are... Learn more about this topic: Skin Cancer: Major Types, Protection & Risk Factors from
Melanoma is a type ofcancerthat can arise from melanocytes, or cells that produce the pigment (melanin) responsible for skin color. As moles are also formed from melanocytes, most lesions that are caused by melanoma look like moles. Often the first sign of melanoma is a change in the shape...
Before looking at melanogenesis, the process through which mature melanocytes produce melanin, it's important to understand the skin anatomy.Depending on the region of the body, the skin measures between <0.6mm (skin of the eyelids) and 2.0mm (e.g. soles of the feet) in thickness and ...
Lighter-skinned people initially suffer from sunburn and then develop a tan. They lack enough eumelanin to darken their skin immediately, but over the next week, increased melanin production will produce a tan. Sunscreen Helps Protect You From The Sun ...
The cause of albinism isa defect in one of several genes that produce or distribute melanin, the pigment that gives skin, eyes, and hair their coloring. The defect may result in the absence of melanin production or a reduced amount of melanin production. ...
light inone studycaused pigmentation in people with light Fitzpatrick II skin, but people with dark Fitzpatrick IV-VI skin had increased pigmentation. One theory is thatvisible light interacts with melanin to form reactive oxygen species, which is why darker skin is more sensitive to visible light...
Pigmentation occurs when the enzyme tyrosinase converts the amino acid tyrosine into melanin. With increased activation, this enzyme can produce more melanin and the skin can appear darker in some areas. These dark marks and pigment spots on the skin are quite common but can be distressing when...
