What Is Fair Skin
Skin has been the fixation of humans for a long time and a lot of cultures across the world pay a great deal of attention to the colour of skin. A lot of events in the human history have come on to be influenced by the colour of human skin and this is the reason why a lot of people have a fixation abut the colour of the human skin. It is generally accepted and known that a rosy and fair skin is attractive and pleasing to the eyes. But what is to the core of fair skin, which comes to decide if it is fair or light toned?
The root cause of the color of skin in humans is a pigment known as melanin which is what causes color to be a part of the human skin. This pigment in the skin is produced owing to a special type of cells in the skin known as melaninocytes. Melanin is what controls the absorption of ultra violet rays from the sun being absorbed in the body. The absorption of ultra violet rays also goes on to effect the folic acid in the skin and this is what determines the darkening of skin tone. The more the melanin, the darker the skin is going to be.
A reduction in the amount of melanin in the skin is what makes it fairer. A skin in which the amount of melanin is low tends to be fairer as the affect of ultra violet rays from the sun is the least in such a skin type. This is the reason why most fairness creams and lotions promise to help your skin boost it’s fairness by acting on the melanin and reducing the harsh affects of the absorption of the ultra violet rays from the sun on your skin.
Apart from the melanin and its action on the skin, there is yet another cause of the colour of the skin. This cause is linked to the genetics of any person and is beyond the control of anyone. There is a specific gene called KIT Ligand which is seen to be the cause of such a variation in skin tone in people. This is one gene which controls and determines the amount of melanin which one shall have in his or her skin and hence control the skin tone as well. This is the reason why a lot of research is being put in to developing medicines which control this gene.
