Freckles are the small, flat brownish spots caused by exposure to the sun and excessive pigmentation of melanin which gives color to the skin. Freckles do not pose any health risk and are therefore, harmless.The main cause for the occurrence of freckles is the sun. Exposure to sun thickens the epidermis (outer layer of the skin) and increases the production of melanin. Dark-skinned people are not too sensitive to the sun exposure as compared to people with fair complexion. However, it doesn’t mean that the dark-skinned people won’t get sunburned. In this skin condition, there is an uneven distribution and huge deposits of melanin under the skin which causes freckles to appear.
