Fact of the day! Freckles… What are freckles? Freckles are a cluster of concentrated melanin, they are commonly more noticeable on people in which have fair skin. A freckle is also known as an ‘ephelis’ Surprisingly freckles do not have a larger amount of melanin producing cells, instead they have cells in which overproduce melanin changing the colour of the skin. This is also a key factor in the varied colouration of our skin tones. Anyone can have freckles, even if we think we do not we will have some unknowingly scattered around the body, the number of freckles we have is down to genetics and the presence of the gene, the formation of our freckles is determined by sunlight, exposure to the sun activates melanocytes resulting in an increase in the production of melanin, this can cause freckles to become much darker hence making them more visible.
