Melanocytes cells produce melanin that determine skin color. The melanin word itself means black pigments or black substance. Melanins are large, black, octopus-shaped cells composed of cytoplasm with many elongated arms. After the production of melanin, melanocytes penetrate nearby cells to inject melanin granules. Injection of melanin granules cause epidermis or skin darkening. The main role of melanin is to absorb UV or ultraviolet rays when it strikes the skin. This way melanin helps reduced the risk for skin cancer by preventing mutation of DNA as well as lessens the speed of skin wrinkling. The production of melanin is genetically controlled. Human skin color is influenced by genes, environment and many other physiological factors especially melanocytes activity. However, we should be aware that sunlight hastens the production of melanin.
The life cycle of the skin cells start at the basal layer which is at the bottom of the skin. The cells receive their nutrients at the basal layer where they divide actively to grow. New cells then pushes older cells through skin layers that gradually make their way to the surface of the skin. These cells received lesser nutrients and lesser moisture as they make their way to the surface of the skin. The cells are already dead and flat when they reached the surface. These accumulated dead skin cells comprised the skin’s top layer and eventually detached to make room for the surfacing cells.
Residue from deodorants, sweat, and dead cells accumulate and make your skin look darker. Clean your armpit area daily by exfoliating. Exfoliation frees the ingrown hair at the same time wipes the skin dead cells. Weave cloths provide a more aggressive means of exfoliation. This may help lessen your problem areas. Just be patient and do this everyday. In good time, you will see results you will be happy with!
