What are they ?
There are different types of spots which can appear in different shapes and colours throughout the body. Some are congenital in nature, present since birth, and others will manifest themselves over time due to other factors.
Most spots are the result of skin hyperpigmentation. Due to excessive exposure to the sun, hormonal variations, genetic predispositions, or skin trauma, hyperpigmentation occurs when the melanocyte cells of the body produce excessive amounts of melanin – the brown pigment that colors the skin. The excessive production of melanin then piles up in some localized areas, causing small spots on the surface of the skin that contrast with the color of the clearer, surrounding skin. Other spots are related to vascular malformation caused by abnormal dilation of the blood vessels. While this phenomenon occurs more often due to skin aging, it can also be attributed to prolonged and repeated exposure to the sun.
It is advisable to monitor the evolution of these types of spots. If they change in size, shape, color or if they are bleeding, it is important to consult a doctor immediately.
