There are very few people who are born without any skin imperfection. But those who have to deal with skin problems especially scars such as Keloids remain quite unhappy about them. This is because of two reasons- first that these scars look ugly and second they are stubborn and don't go away easily.
Keloid scars can be defined as anomalous scars that tend to grow beyond the original site's boundary. These can be described as ill-defined as well as raised growth of skin in the damaged skin area. Although anyone can get these scars but some of the ethnic groups are at greater risk of developing these scars. Hispanic or African-American people are sixteen percent more susceptible as compared to rest of the people around world.
Some specific parts of the body seem to be more vulnerable to Keloids scar. The upper back, the sternum, back of the neck, earlobes and upper arm region are some of the most common sites. The reason of their occurrence is still not understood but experts believe that skin trauma is the commonest factor.
Most of the experts think that that the muscle and/or skin tension contributes to the formation of these ruthless scars. Some other potential factors include the presence of foreign body at a wound site, repeated trauma to the affected area and infection or skin tension in a wound.
Genetic component is also likely to be associated with keloid scarring. The presence of Keloids on the body of a family member puts you at a higher risk of developing them. In fact, extensive studies have led to plenty of theories. Some doctors believe that Keloid scarring occurs due to blockage in small blood vessels.
But still there is no clear-cut theory that can explain the cause of Keloid scarring. Figuring out the exact cause will help in the advancement of treatments and preventive medicines. There are surgical as well as non-surgical treatments to combat with Keloid scarring. It might not sound very good but unfortunately there is nothing that can be done to prevent the formation of these scars. However, thankfully, there are various reliable scar reduction gels available online. Many of these gels are silicone based and thus ensure great results.
