Black spot / Hyper pigmentation
Age spots are the result of an excess production of melanin, or skin pigment. Doctors don’t always know why age spots develop. Skin aging, sun exposure, or other forms of ultraviolet (UV) light exposure, such as tanning beds, are all possible causes.A common cause of hyperpigmentation is an excess production of melanin. Melanin is a pigment that gives skin its color. And it’s produced by skin cells called melanocytes. Several different conditions or factors can alter the production of melanin in the body.Hormonal influences are the main cause of a particular kind of hyperpigmentation known as melasma or chloasma. It’s particularly common among women, as it’s thought to occur when the female sex hormones oestrogen and progesterone stimulate the overproduction of melanin when skin is exposed to the sun.Dark spots, patches and other marks on the face may be due to excess secretion of melanin on the skin. Some factors that can lead to this condition include over exposure to the sun, hormone imbalance, pregnancy, certain medications, vitamin deficiencies, lack of sleep and too much stress.This nonmelanoma skin cancer may appear as a firm red nodule, a scaly growth that bleeds or develops a crust, or a sore that doesn’t heal. It most often occurs on the nose, forehead, ears, lower lip, hands, and other sun-exposed areas of the body. Squamous cell carcinoma is curable if caught and treated early.
