It is alarming to see dark spots appearing on your skin and affecting your looks. It is perfectly possible for this skin problem to be treated effectively, but in order for this to happen its causes have to be identified first. Discover the most common causes of dark spots to ensure that you will get clearer and even more beautiful skin.
Sun Exposure
This is the most common reason why dark spots appear on the skin. The UV light of the sun causes damage to the cells in the upper layers of the epidermis. Usually, this damage occurs due to long unprotected exposure to the sun. The cell damage manifests itself in the form hyperpigmentation. The spots usually come in different shades of brown and sometimes gray.
There are three main types of dark spots caused by UV damage. The Melasma spots are typically big and connected to each other to form clusters. They typically appear on the face. They are most common in young people and young women, in particular.
Ephelides, which are informally known as freckles, are perhaps the most common of all dark skin spots. They are small, but typically cover fairly big areas of the skin. Their color ranges from red to brown. They can appear at any age including early childhood. They most often occur on the face and the upper part of the body. The cheeks and arms usually have the most freckles.
The so called age spots which tend to appear on the skin when people get older are called solar lentigines. They are caused by long-term exposure to the sun and are extremely common. Their color typically ranges from light to dark brown. They can have different sizes. Many small spots can form a cluster or there may be several bigger ones fairly close to each other. They appear on the parts of the skin which get the most sunlight such as the forehead, temples, chest, arms and hands.
Hormonal Changes
Changes to the hormonal balance, especially in women, can lead to the appearance of dark spots on the skin. Most often, these occur during pregnancy. They can also be caused by the intake of birth control pills and medications which trigger hormonal changes. The spots usually go away naturally after the hormonal balance in the body is restored.
Medical Conditions
Skin disorders, liver disease and some hormonal disorders such as Addison’s disease can also cause dark spots. When they are properly treated, the skin will get improvement as well. It is also worth noting that it is common for hyperpigmentation to occur after skin trauma which has caused inflammation. Dark spots can appear on the place of healed acne pimples, for instance. The risk of this is lower if the condition has been treated properly.
Finally, you should know that it is fairly uncommon for melanoma, which is the most dangerous skin cancer, to be confused with dark skin spots. Still, it is always best to have such spots checked by a dermatologist who will recommend the most appropriate treatment given the cause of the problem and other factors such as age and overall health.
