Freckles are small, flat, brown spots found on the skin. They may vary in colour from red to brown. They are extremely common and completely harmless. They are very common among light-skinned people due to lower presence of melanin which is a chemical produced by the skin cells which protects the skin from sun damage. Freckles develop because of irregular distribution of melanin in the skin. Excessive production of melanin at one place will result in freckles.
Freckles occur as a result of exposure to the sun and are commonly found in areas exposed to sun rays. Freckles are mostly found on the face, shoulders and arms.
Freckles develop randomly either as an individual spot or in clusters making them largely visible on the skin.
Fair complexioned people are more prone to development of freckles as this type of skin has lesser presences of melanin and burns easily.
Freckles in most cases are harmless and treatment is not required other than for cosmetic reasons.
Since lighter-skinned people freckle easily and continuous skin damage by the sun rays can increase your chances of getting skin cancer hence preventive steps needs to be taken. Freckles are a sign of skin which is vulnerable to sun burn which may lead to skin cancer.
