17 Facts About Light skin

Light skin is a human skin color that has a base level of eumelanin pigmentation that has adapted to environments of low UV radiation.

Light skin is most commonly found amongst the native populations of Europe and Northeast Asia as measured through skin reflectance.

People with light skin pigmentation are often referred to as "white" or "fair", although these usages can be ambiguous in some countries where they are used to refer specifically to certain ethnic groups or populations.

Lighter skin colour has evolved independently in ancestral populations of north-west and north-east Eurasia.

Light skin's suggests that people living far from the equator developed light skin to produce adequate amounts of vitamin D during winter with low levels of UV radiation.

Some people of the polar regions, like the Inuit, retained their dark Light skin; they ate Vitamin D-rich seafood, such as fish and sea mammal blubber.

Resistance to cold injury hypothesis claimed that dark Light skin was selected against in cold climates far from the equator and in higher altitudes as dark Light skin was more affected by frostbite.

Supposition that dark Light skin evolved in the absence of selective pressure was put forward by the probable mutation effect hypothesis.

The main factor initiating the development of light skin was seen as a consequence of genetic mutation without an evolutionary selective pressure.

Humans with naturally occurring light skin have varied amounts of smaller and sparsely distributed eumelanin and its lighter-coloured relative, pheomelanin.

People with very light skin, the skin gets most of its colour from the bluish-white connective tissue in the dermis and from the haemoglobin associated blood cells circulating in the capillaries of the dermis.

People with very light skin make very little melanin in their melanocytes, and have very little or no ability to produce melanin in the stimulus of UV radiation.

People with moderately pigmented Light skin are able to produce melanin in their Light skin in response to UVR.

Humans with light skin pigmentation living in low sunlight environments experience increased vitamin D synthesis compared to humans with dark skin pigmentation due to the ability to absorb more sunlight.

Almost every part of the human body, including the skeleton, the immune system, and brain requires vitamin D Vitamin D production in the skin begins when UV radiation penetrates the skin and interacts with a cholesterol-like molecule produce pre-vitamin D3.

Individuals with lightly pigmented skin who are repeatedly exposed to strong UV radiation, experience faster aging of the skin, which shows in increased wrinkling and anomalies of pigmentation.

Light-coloured skin has been suspected to be one of the contributing factors that promote wrinkling.
