The epidermis is itself comprised of four further layers: the lowest being the basal cell layer, which is where skin cells called melanocytes continuously make the skin''s pigment, melanin. 90 per cent of cells in the epidermis are keratinocytes, which multiply and migrate upwards from the ...
Ultraviolet (UV) rays.Melanin helps protect your skin from these harmful rays, including blue light andUVA, UVB, and UVC. Melanin absorbs them and spreads them out in your skin's top layer. That keeps them from doing damage deeper inside your skin. Reactive oxygen species (ROS).These are ...
Melanin is produced by melanocyte cells in the epidermis, or outermost layer of skin (the thicker, tougher layer underneath is called the dermis). These melanocytes lie in the lowermost layer of the epidermis, called the stratum basale or "basal layer." Melanin comes in several subtypes, the ...
