Freckles are harmless concentrations of melanin that cause dark spots on the skin. Freckles are flat small tan or light-brown spots on sun-exposed skin. Freckles are more common on the face of red-headed, poorly pigmented individuals.The exposure to UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darker and more visible. This means that one who has never developed freckles may develop them suddenly following extended exposure to sunlight.
