It is a widely-known fact of life that skin is not even. However treated, the human skin has many imperfections that include marks, spots, lines, change of color and of course, freckles among many others.
People who have freckles may have wondered throughout their lives about the reasons behind their freckles. However, people whose skin is covered with even darker freckles than usual may wonder what the common causes of dark freckles are.
On the one hand, there is an answer to this age-old question. On the other, the answer may not throw much light on how to get rid of dark freckles.
Common Causes of Dark Freckles: What you should Know
There is not a single reason that can explain the existence of freckles that are darker than usual. Apparently, there is a wide variety of reasons that can help to explain this issue much better.
These are the most common causes of dark freckles:
Genetic Factors: Scientific studies have proved that freckles are caused by an uneven distribution of the melanin pigment on the human skin. Since not all people present this genetic layout, those who do have a higher chance of developing freckles when they grow older. This genetic pattern is evident in some families whose members all present freckles, either on their faces, or arms and backs.
Some studies reveal that there is a close connection between having darker freckles and certain racial types. People who are overall darker, have a healthy distribution of melanin, thus have lower chances of developing freckles.
On the other hand, most light-skinned people get red easily when exposed to the sun and may develop certain conditions. Since melanin is not fully-distributed in this case, but grouped in small clusters, then freckles are bound to spurt when activated by the sun.
Sun Exposure: Although common, this is one of the most relevant causes. Even when a person presents a genetic disposition toward having freckles, this does not mean that those freckles must be dark.
If the person however, intensifies its sun exposure, there is a high chance that this irregular melanin pattern translates into darker freckles. Science has explained that direct exposure to UV-B radiation activates melanocytes, which –in turn- stimulate melanin production. It is this increase in production what will make the color of a person’s freckles more intense and less easy to conceal. This is particularly so with those freckles found on the human face.
The best way to prevent your already-existing freckles to get darker is to wear the right type of sun screen factor, plus, avoiding sun exposure altogether, especially during the “dangerous hours”.
Certain Skin Conditions: People who have certain skin conditions should not feel surprised if their freckles turn out to be darker than other people’s.
Xeroderma pigmentosum for example, is a rare condition in which patients begin to notice darker marks on their faces. The hyper pigmentation is produced because the person is highly sensitive to all ultraviolet sources of light. As a natural skin reaction, dark spots appear on the person’s face.
