It is a well-known fact that chronic sun exposure can result in premature aging of the skin. While limited sun exposure has its health benefits, particularly providing vitamin D, prolonged exposure can lead to permanent damage. The main culprit lies in the UV rays. While covering up and wearing sunscreen help, they certainly do not block out all UV rays.
Chronic sun exposure can lead to a variety of problems for your skin, including freckles, wrinkles, skin thinning, liver spots, leathery skin, white spots, and brown patches called melasma. The substance that maintains the normal color of your skin is called melanin. Increased sun exposure leads to increased melanin levels, which in turn cause dark spots or hyperpigmentation. These appear as flat, freckle-like round spots with a regular or irregular border. The most common locations for sunspot development are the face, neck, décolletage, upper back and shoulders, forearms, and back of the hands.
