Melanin protect your skin

As people fret over the color of the skin, the good news is that it is this color-producing pigment that is your biggest shield against the sun. It works like this.

The outer layer of the skin contains melanocytes – they makeup 20-25 percent of the cells found here. Melanocytes are vital pigment cells, which produce the big M –melanin, a protective dark pigment.

When the skin gets exposed to the sun, the melanocytes start to produce more melanin and they spread over to the neighboring cells as a protective film. It accumulates around the vital structure protecting, especially our DNA, from damage. The purpose is to prevent harm to the skin, and in worst cases, skin cancer.

Remember that an exotic tan is nothing but the skin’s way of donning a protective garb against harmful rays. Everyone has the same amount of melanocytes, but the different lies in the amount of melanin produced. Darker people tend to produced more melanin, which also explains the colour of the skin (as the amount of melanin is also the deciding factor for the color of the skin). Therefore, a dark skinned person has a natural protective layer as opposed to those with a lighter color skin. If people with lighter skin protect themselves sufficiently, they can fare as well under the sun.

However, it is not necessary that darker people age later in life. There might be other factors such as stress, smoking, alcohol, airborne pollutants, chemical irritants and lack of proper diet of vitamins, proteins and minerals which can cause the skin to age.
