There was a significant negative correlation between serum 25-Hydroxyvitamin D and duration of keloid. Accordingly, low serum and tissue 25-Hydroxyvitamin D and deficient tissue vitamin D receptors contribute to the pathogenesis of keloids.
Conclusions: Intralesional vitamin D is an effective and safe method in treatment of keloid scars. Ultrasound is a useful method in assessing the improvement of keloids after treatment.
Vitamin D deficiency and certain genetic polymorphisms in the vitamin D receptor seem to be associated with keloid development.
Collagen — a protein found throughout the body — is useful to wound healing, but when the body produces too much, keloids can form. Keloid growth might be triggered by any sort of skin injury — an insect bite, acne, an injection, body piercing, burns, hair removal, and even minor scratches and bumps.
Stress hormones could activate α-ARs to promote keloid formation by enhancing growth-related responses and aggravating the local hypoxia environment. Furthermore, their enhanced expression was associated with cell proliferation, inflammation, and uncomfortable symptoms of pain and pruritus in hypertrophic scars.
Pregnancy: The hormonal changes that occur during pregnancy increase the risk of developing a keloid.
Keloids are most common in people younger than 30. Black people, Asians, and Hispanics are more prone to developing keloids. Keloids often run in families. Sometimes, a person may not recall what injury caused a keloid to form.
Abstract. Background: Keloid is a fibrotic skin disease for which immune cell infiltration is a primary pathological hallmark. Meanwhile, in autoimmune diseases, triggering of the inflammation response can lead to tissue injury and subsequent organ fibrosis.
After the wound heals, apply silicone gel sheets or silicone gel. You can buy both of these products without a prescription. They can help prevent a keloid. To get the best results, you apply a new sheet or gel to the area every day.
Keloid surgery: Your dermatologist can surgically cut out the keloid. While this may seem like a permanent solution, it's important to know that nearly 100% of keloids return after this treatment. To reduce the risk of a keloid returning after surgical removal, most patients have another treatment after surgery.
There was a significant negative correlation between serum 25-Hydroxyvitamin D and duration of keloid. Accordingly, low serum and tissue 25-Hydroxyvitamin D and deficient tissue vitamin D receptors contribute to the pathogenesis of keloids.
Among 41 patients who had their keloids or hypertrophic scars covered with zinc tape, the size of the scars in 23 patients was reduced to the level of the surrounding skin within the mean treatment time of 6 months.
However, several studies by Louw have suggested, mainly from the nutritional point of view, that essential fatty acids may be involved in the formation and progression of keloids [7–10], which has galvanised research into the contribution of nutrition in keloid development and progression.
People with darker skin, such as black, Hispanic, and Asian people, are 15 to 20 times more likely to get keloids. But, some people with lighter skin also get them. Keloids are more common in people younger than 30 years, in pregnant women, and in teenagers going through puberty.
Keloids result from abnormal wound healing in response to skin trauma or inflammation. Keloid development rests on genetic and environmental factors. Higher incidences are seen in darker skinned individuals of African, Asian, and Hispanic descent.
Stress promotes keloid formation by causing dermal distortion and compression which subsequently stimulate proliferation and enhanced protein synthesis in wound healing fibroblastic cells.
Keloids are the result of excessive collagen production. Collagen is a substance produced by a type of skin cells called fibroblasts. These cells are found in the dermis, the deeper level of the skin. Patients who keloid have more dermis – and more cells that generate dermis – than patients who do not keloid.
Abstract. Keloid is a skin disease characterized by exaggerated scar formation, excessive fibroblast proliferation, and excessive collagen deposition. Cancers commonly arise from a fibrotic microenvironment; e.g., hepatoma arises from liver cirrhosis, and oral cancers arise from submucosal fibrosis.
Patients at high risk of keloids are usually younger than 30 years and have darker skin. Sternal skin, shoulders and upper arms, earlobes, and cheeks are most susceptible to developing keloids and hypertrophic scars.
How common are keloids? About 10 percent of people experience keloid scarring. People under the age of 30 may be particularly at risk. People of African, Asian, or Latino descent, pregnant women, and those with a family history of keloids are more susceptible to this type of scarring.
