Hence the balancing act. A melanocyte is a type of cell thats primarily located in the basal layer of the epidermisMelanocytes produce melanin a brown pigment that is responsible for skin coloration and protecting against the harmful effects of UV light. The three lines of defense that are essential for proper skin health include shielding against UV radiation protecting the skins barrier integrity and normalizing cellular processes to counteract damage.
When exposed to ultraviolet radiation the melanocytes release extra melanosomes thus making the skin darker and completing melanogenesis which is defined as the UVR-induced production and oxidation of melanin ie the process of developing facultative pigmentation better known as cosmetic tanning. Melanin Melanin is the only one of the three pigments melanin carotene and hemoglobin that contribute to skin color that is actually produced in the skin itself. Melanin is the only one of the three pigments melanin carotene and hemoglobin that contribute to skin color that is actually produced in the skin itself.
Which skin pigment is made in the skin as a natural defense against UV radiation. People with darker skin have more melanin so they can filter out more UV radiation and are less likely to get skin. Melanocytes are also present in the hair and in the irises of the eyes.
The blood capillaries minute vessels in the skin dilate with aggregations of red and white blood cells to produce the red coloration. Carotenes kair-o-tens are a group of lipid-ioluble plant pigments that range in color from violet to red-yellow to orange-yellow.
