A keloid is a thick, raised scar, not a pimple. It forms as an overgrowth of scar tissue due to an excessive healing response (too much collagen) following skin injury, such as acne, piercings, or surgery. Unlike acne, keloids are firm, often itchy, and grow beyond the original wound boundary.
Causes of keloid scars
A keloid scar is when a scar keeps growing and becomes bigger than the original wound. It can happen if you have too much of a substance called collagen in your skin. It can happen after any sort of injury or damage to your skin such as a cut, burn, surgery, acne or a body piercing.
Ear keloids are firm, rubbery, fibrous nodules that form on the ear after minor trauma, most commonly after ear piercing. They can occur in earlobes as well as in the skin and cartilage higher on the ear. Ear keloids can vary in color, from flesh-colored to pink to dark brown. Keloids can be itchy or painful.
Conclusion. The higher tendency to develop migraines in the keloids group in comparison with the non-keloids group suggests that keloids could be a predisposing risk factor for migraine development in adults. Keloids patients who complain of headaches should be examined for migraines.
A keloid scar is a thick raised scar. It can occur wherever you have a skin injury but usually forms on earlobes, shoulders, cheeks or the chest. If you're prone to developing keloids, you might get them in more than one place. A keloid scar isn't harmful to your physical health, but it can cause emotional distress.
Conclusion: Keloids never completely disappear to leave skin with normal texture, however they can resolve (flatten and soften) so they no longer burden patients in approximately one third of cases. Scars resolving spontaneously do so early in the disease. Those that don't may resolve after many years of treatment.
Keloid and hypertrophic scars are common types of scarring that can occur as a result of the acne healing process. They appear as raised lesions of scar tissue on the skin and are a result of the overgrowth of fibrous tissue in the region where the acne lesion had developed.
Generally, they contain relatively acellular centers and thick, abundant collagen bundles that form nodules in the deep dermal portion of the lesion. Keloids present a therapeutic challenge that must be addressed, as these lesions can cause significant pain, pruritus (itching), and physical disfigurement.
Keloids may continue to grow slowly for weeks, months or years. They eventually stop growing but do not disappear on their own. Once a keloid develops, it is permanent unless removed or treated successfully.
Texture often hard and rubbery or soft and doughy
When you touch a keloid, you're most likely to feel one of these textures. A few keloids have a texture that's somewhere in between hard and soft.
Over months or years, scars can grow from the size of a pencil top eraser to a grapefruit or larger. Patients tend to first notice symptoms between ages 10 and 30, with the 20s as the prime age to develop keloids. The condition can range from mildly annoying to socially limiting.
To support keloid therapy, it is advisable to limit or avoid pro-inflammatory foods such as processed meats, sugary snacks, refined grains and alcohol in excess. These foods can contribute to systemic inflammation and may impede the healing process.
Anyone can get a keloid on their ear. However, you're more likely to develop a keloid on your ear if: You're Black, Hispanic or Asian. You have ear piercings.
Keloids are most common in people younger than 30. Black people, Asians, and Hispanics are more prone to developing keloids.
This suggests an impaired function of small C-nerve fibres in keloids with the severity of neural damage correlating with itch severity. Another proposed mechanism suggests that the keloid lesion itself induces a compressive neuropathy-like phenomenon.
After the wound scabs, 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.
Although the likelihood of transformation into cancer is extremely low, continuous trauma to a keloid (such as scratching or hitting) may, in very rare cases, lead to the development of skin cancers.
The dysregulation of the wound-healing process in keloids is marked by persistent inflammation, excessive fibroblast activation, and an imbalance between collagen synthesis and degradation. This abnormal healing is characterized by an overproduction of type I and III collagen, leading to dense, fibrotic tissue.
Treatment
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.
Natural methods (massage, onion extract, pressure) offer comfort and texture support—but aren't enough to flatten keloids alone. Silicone gel remains the most effective non-prescription treatment for reducing keloid height, color, and firmness.
It forms months to a year after the injury that caused it. The scar grows larger than the initial wound. Keloids don't fade over time. A dermatologist may offer treatments like corticosteroid injections or pressure garments to reduce its size and appearance.
Nodular acne pimples appear as red bumps on the surface of your skin, with a firm lump deeper beneath the skin. Nodular acne is a type of inflammatory acne that occurs when hair follicles in your skin are blocked by excess oil (sebum), dead skin cells and bacteria.
Keloids usually don't go away on their own. They may continue to grow over time. Seeking dermatological advice early on is crucial for proper management and to prevent them from becoming larger.
Rolling scars are a common type of scarring that can occur as a result of the acne healing process. They appear as indents in the skin and tend to measure a few millimetres wide.
