Melanin

It is produce by specialized skin cells called melanocytes. Every body has the same quantity of melanocytes, and the amount of melanin produced determines our skin colour.

People with darker skin produce more quantity, that is why black and dark skinned people are better protected from uv rays, and premature aging skin. Fair skinned people are less protected, and are more susceptible to skin cancer. The lack of this pigment causes albinism.

There are two types:

• Eumelanin: is more abundant and darker.
• Pheomelanin: red or yellowish colour. More abundant in red or blondes.

Whether from a day on the beach or hours spent in a tanning salon, the "tan" color your skin gets after baking under UV rays, is a sign of skin damage.

When it's exposed to UV rays our skin produces a pigment called melanin, to protect skin cells from damage. When our skin is exposed to UV rays it produces more quantity, and may become darker over the next few days.

Everyone, no matter their skin tone, is at risk of skin damage. There are six skin categories recognized by the FDA and the AAD. Each is classified by sensitivity to the sun and typical skin tone. Check out the table below to see which skin type you are
