For some people, freckles are a cosmetic obstacle. For others, they're a hot fashion accessory. But what causes the skin sprinkles that some people call "angel's kisses"? Basically, it's all in your genes—and the sun. Melanin shows up when ultraviolet radiation UV hits the skin. UV is damaging, and melanin protects the skin from that damage by darkening it—think of it like your skin slipping on a pair of shades. Melanin is produced in a type of cell called melanocytes.

Red hair or ginger hair occurs naturally in one to two percent of the human population , appearing with greater frequency two to six percent among people of Northern or Northwestern European ancestry and lesser frequency in other populations. It is most common in individuals homozygous for a recessive allele on chromosome 16 that produces an altered version of the MC1R protein. Red hair varies in hue from a deep burgundy or bright copper , or auburn , to burnt orange or red-orange to strawberry blond. Characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin , it is associated with fair skin color , lighter eye color , freckles , and sensitivity to ultraviolet light. Cultural reactions to red hair have varied from ridicule to admiration with many common stereotypes in existence regarding redheads.

They're fiery and dangerous, or they're clownish and weak. They're total geeks in public, but they're wild in the bedroom. They don't have souls, so they'll steal yours. The list of myths and stereotypes about redheads go on and on, showing just how stigmatized people with this unique phenotype really are. But all of the joking about the red-headed step-child aside, it turns out that our ginger sisters and brothers really do have a special set of attributes that their blonde and brunette counterparts don't.

Almost all of us have freckles, some more than others. Many of us are too dark for them to be seen, but they are very visible in those with a fair complexion. Even though they cover our whole body, most of us know almost nothing about them. The answer is no! This because of how freckles are formed on the body. Freckles are caused by exposure to the sun. The number of freckles you have is determined by genetics.

Scientists looking in to why some people age better than others have found people who carried the MC1R gene looked much younger than their real age. The MC1R gene - is critical for making melanin, which affects skin pigmentation and protects against UV radiation from the sun. But the variations of the gene also leads to red hair and freckles. The study into ageing was conducted by the Erasmus University Medical Centre in the Netherlands and Unilever and published in the journal Current Biology. Researchers asked people to assess the faces of 2, people and recorded what ages people though they looked. This age was then compared to their true age. It showed some variants of the gene - which comes in many forms including many of which cause red or ginger hair - led to people looking, on average, two years younger than those with other forms of MC1R.
