What Are Liver Spots?
Liver spots
Liver spots, also known as sun spots, or more technically solar lentigines or solar lentigo are groupings of pigment most frequently from over exposure to the sun and the sun’s ultra violet rays. Liver spots can be caused by coagulation of blood that occurs during the bruising process in the surface of the skin which can create dark spots or pigments afterwards.
The spots are also sometimes known as age spots or agespots due to the fact that they most frequently develop in persons in their 50’s or older. Sunspots frequently grow on the backs of hands or anywhere that is consistently exposed to sunlight, such the face, arms, shoulders and back. For those who tan their entire bodies more frequently, the spots are also common in the legs, feet, chest and other areas prone to prolonged sun exposure.
What Are Liver Spots?
So, what are liver spots? Liver spots, or ’solar lentigines’ are surface area collections of melanin which has accumulated in the top layer of the skin — also known as the epidermis. Ephelides are seen commonly in those with fairer skin and those with lighter skin prone to sunburns. Age spots, or lentigines typically manifest after some years, and while most commonly found in blonde or redheads with blue eyes and fair skin, will appear on all skin types after years of prolonged sun exposure.
Age spots, or liver spots, are caused by repeated and prolonged sun exposure, sun burns, and usually appear later in adult life. On the other hand even children can experience the occurance of ephelides after brief periods of sun exposure.
In most cases pigmented spots on skin not subjected to repeated sun exposure is quite rare, so if you wish to avoid the appearance of liver spots or even freckles your best defense is to avoid the sun and use a broad spectrum sunscreen with a strong SPF rating for blocking the suns harmful uVa and uVB rays which can stoke the melanocytes into the creation of melanin. In addition, if you’re undergoing a treating for age spot removal or liver spot removal, a sun screen can help with the unwanted reappearance of your spots.
Are Liver Spots Freckles?
Lentigines and age spots are not the same as freckles. The spots found on the faces and arms of fair skinned people called freckles are caused by melanin pigments which react to the sunlight in fair-skinned people. Some people believe that liver spots and age spots are from an accumulation of the “ceroid” pigment in the skin of older people, in most cases, the mechanism of action is due to overproduction of melanin as well.
Why are They Called Liver Spots?
Some believe dark spots are the manifestation of “free radical” destruction within the body. Fats, subjected to pre-oxidation in the cells in place of in the liver. The idea is that free rads make waste materials in cells throughout the body. The contributing factors include, diet, lack of exercise and over exposure to the sun. This is the reason you’ll hear foods described as ‘anti-oxidents’ – and foods with ‘anti-oxidents’ being considered good for the appearance of youthful skin.
