Although creams containing onion extract or vitamin E are widely used to treat scars, a review in the American Family Physician and a dermatological surgery study found that these ingredients did not help with keloids.

Silicone plasters and gels

Like laser therapy, silicone can be used to reduce the size of the keloid by itself, and the application of silicone gel can also be used as part of the repair process to prevent keloid recurrence. Inject a steroid into the scar, this is a common treatment to reduce the size of the keloid if creams or silicone strips are not effective. This treatment can be combined with other injection treatment options to further reduce the scar.

During surgery, your dermatologist may remove excess scar tissue and use skin grafts from other parts of your body to help heal. Laser Treatment. For small keloids, laser treatment can shrink or even completely remove the scar. Laser treatment of keloids For certain types of scars, including some keloids, your doctor may recommend laser treatment. However, laser treatment may aggravate keloids, leading to increased scarring and redness.

Patients who develop keloids may have scars that are much larger in width and height than the original lesion. Unlike other types of scars, keloid scars can spread and grow beyond the original site of injury. Unlike other scars, which can be flat and lightly colored, keloids are often bumpy and wrinkled. Keloids are inherited and rarely turn into fair skin.

Keloid scars can be caused by inflammation from ear piercings, tattoos, pimples, ingrown hairs, or even minor mechanical injuries such as rubbing against the skin or hitting objects. Keloid scars sometimes appear 3 months or more after a skin injury. Keloid growth can be caused by any skin injury: insect bites, acne, injections, piercings, burns, hair removal, and even minor scratches and bumps.

Doctors define hypertrophic scars as scars that do not extend beyond the original wound, and keloids as scars that extend into surrounding normal skin. The main apparent difference between hypertrophic and keloid scars is the extent to which the scar has spread around the original wound.

Thick tissue grows out of the healing area, making the scar larger than the original wound. After the keloid is removed, the scar tissue may grow back and sometimes it becomes larger than before. To prevent keloids from developing after minor skin trauma, start treatment right away.

It can happen anywhere there is a skin lesion, but it usually occurs on the earlobes, shoulders, cheeks, or chest. Less commonly, keloids can form in places where the skin has no visible damage.

Although keloids are a type of scar tissue, they can grow much larger than wounds. Once a keloid has formed, it can grow for months or even years, hiding the original lesion. Domed or irregular shape a When a keloid is caused by a surgical incision or trauma, the keloid tissue may continue to grow for some time after the wound is closed. Once a keloid stops growing, it becomes darker than human skin.

On the chest, legs, or arms, keloids are most likely raised scars with a flat surface. A keloid (eg, “KEE-faithful”) is a scar that is larger and wider than the original lesion. Keloid scars are most commonly found on the breastbone, shoulders, upper chest and back, earlobes and face.

They can develop after very light skin lesions, such as acne or piercings, and spread beyond the original area of ​​the skin injury. It is not known if they occur more frequently after piercing than other skin lesions. Although they may look and feel like a keloid scar, these bumps usually appear on the legs, do not cause damage, and usually do not grow.

In some cases, additional scar tissue grows to form smooth, hard growths called keloids. Unlike other types of raised (hypertrophic) scars, keloids grow beyond the original damage to the skin, says Jason M. Preisig, MD, a dermatologist at Mercy Medical Center in Baltimore. This leads to chronic inflammation, which may also explain the aggressive growth of keloids. But in about 4-6% of patients, the healing process goes too far, resulting in thick, visible scars called keloids.

Keloid scars are thought to be caused by an inherited / genetic predisposition and it can be difficult to prevent further keloid scars from enlarging. Genetic Risk Factors That Increase Skin Inflammation Some patients with keloid and hypertrophic scars have a family history of abnormal scars, suggesting that these scars may be caused by genetic factors.

In addition, there is clinical evidence that dark-skinned patients are 15 times more likely to develop pathological scars (mainly keloids) than light-skinned patients. The factors that determine whether a “normal” keloid or scar develops are not entirely clear, but we do know that keloids are more likely to develop on certain parts of the body (such as ears, shoulders, chest, neck, and back). ) and under certain conditions (for example, if the injury took a long time to heal). Keloid prevention through proper wound care and avoiding skin damage such as piercings is the best strategy for people prone to keloids.

A keloid forms due to the skin’s overreaction to damage. A keloid is an overgrown scar left by wounds such as surgical incisions, lacerations, or burns. Keloid and hypertrophic scars are caused by skin lesions and irritations, including trauma, insect bites, burns, surgery, vaccinations, skin piercings, acne, folliculitis, chickenpox, and herpes zoster infections.

Unlike keloids, hypertrophic scars are smaller and may go away on their own over time. While hypertrophic scars and keloids occur on burned areas of the skin, they never develop on frostbite areas. This suggests that these pathological scars are caused by damage to this layer of the skin and subsequent aberrant wound healing in it.

The scar most often appears on the upper torso – back, chest, shoulders, shoulders – and on the skin covering the joints. Scar tissue can form from skin lesions or wounds resulting from accidental injury, inflammation, burns, and surgical incisions.

There are many other types of skin scars, each with a different appearance, cause, and treatment. For example, some people with acne scars may develop only atrophic scars, which are flat, shallow depressions in the skin, while others with acne scars may develop keloids. In addition, if keloids can continue to grow for months or years after they develop, hypertrophic scars usually diminish over time.
