Hyperpigmentation is a common skin condition where patches of skin become darker than the surrounding area. This discoloration is typically caused by an excess production of melanin, the pigment that gives skin its color. Dark spots, also known as age spots or sun spots, can occur due to various reasons including sun exposure, hormonal changes, acne scars, and inflammation.

What Causes Dark Spots? Dark spots are primarily the result of prolonged sun exposure which stimulates excess melanin production to protect the skin from UV rays. Other factors such as acne, certain medications, and hormonal changes can also contribute to their formation.
