Freckles can normally be found on the face. Especially to the areas that are expose to sunlight. They say that its genetically and is related to the presence of the dominant melanocortin-1 receptor MC1R gene variant. The formation of freckles is triggered by exposure to sunlight. The exposure to UV-B radiation activates melanocytes to increase the melanin production, which causes freckles to become darker. However, freckles may appear to anyone regardless the background since you can have freckles from the exposure of sunlight without skin protetion.

According to wikipedia.com Ephelides is a genetic trait. It is used to describe a freckle that is flat, light brown or red, and fades in the winter. Ephelides are more common in those with light complexions, although are found on people with a variety of skin tones. The regular use of sunblock can inhibit their development.

Liver spots (also known as sun spots and Lentigines) are freckles that sometimes do not fade in the winter. Rather, they form after years of exposure to the sun. Lentigines are more common in older people.

Suncreen have been used by millions of people to prevent the freckles from multiplying. You can find lots of sunscreen creams from your local drugstore and if you can affors to let the freckles removed by laser treatment. However neutrogena sunscreen is better for preventing the freckles from multiplying. I’ve been using this for quite sometime and its effective. You can use pure emu oil to lighten it up.
