Hypertrophic scars are contained within the site of injury and may regress over time, while keloids spread beyond the borders of the initial injury and do not regress. On histological examination, hypertrophic scars tend to have collagen in a wavy, regular pattern, whereas keloids have no distinct pattern of collagen.
They include: Hard or thickened raised tissue over your wound site. Pink to red to purple skin color over your wound site. Scar appears most commonly on the upper trunk of your body – your back, chest, shoulders, upper arms – and skin that covers your joints.
Hypertrophic scars develop in 1 to 2 months after injury, whereas, keloids develop months to years after the initial injury. Hypertrophic scars and keloids often cause irritation, pruritus, and even neuropathic pain. Severe hypertrophic scars or keloids over a large area can cause contractures that may be disabling.
A keloid scar usually appears a few weeks to years after you damage or injure your skin, such as after a cut, burn or acne. Keloid scars are usually raised, hard, smooth and shiny. They can be skin colour, pink, red, purple, brown, or darker than the skin around them.
Shiny, hairless, lumpy, raised skin. Varied size, depending on the size of the original injury and when the keloid stops growing. Varied texture, from soft to firm and rubbery. Reddish, brown or purplish, depending on your skin color.
It appears gradually. It can take as long as 3 to 12 months or even longer before you to notice a keloid beginning to develop; most tend to appear within a year of the original skin damage. It may also grow quickly. Sometimes keloids spread fast, and may, for example, triple in size in as little as a few months.
Does Bio-Oil Skincare Oil work on keloid scars? Bio-Oil Skincare Oil has been clinically proven to improve the appearance of many types of scars1, but its impact on keloid scars can be limited due to their nature.
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.
It usually ends up being darker than the person's skin, with the border being darker than the center. Feel different than the surrounding skin. Some keloids feel soft and doughy. Others are hard and rubbery.
There are no proven methods of removing keloid scars naturally. Some clinical studies have shown that onion extract used orally or on the skin might possibly be effective in improving the appearance of keloid scars and reducing itchiness and discomfort.
PATHOPHYSIOLOGY OF HYPERTROPHIC SCARS
The wound healing process involves the following phases, inflammation phase (the first 2 to 3 days after injury), proliferation phase (4 days to 2 weeks including ECM formation, angiogenesis, and reepithelialisation), and maturation phase (several months even lasting to one year).
Unlike keloid scars, hypertrophic scars do not extend beyond the boundary of the original wound. They may continue to thicken for up to 6 months before gradually improving over a few years.
With the right treatment or combination of treatments, hypertrophic scars can be flattened and made less noticeable. Removing excess tissue can improve the movement of the skin and relieve itching or discomfort.
Research has shown that gently massaging a scar may break down scar tissue as it forms. It may also prevent hypertrophic scars or keloids from developing after an injury.
Massaging your scars is important. It keeps the tissue around the incision loose so it doesn't “stick” to the tissue underneath. Wait until after your skin has healed before you start massaging your scar.
Hypertrophic scars are contained within the site of injury and may regress over time, while keloids spread beyond the borders of the initial injury and do not regress. On histological examination, hypertrophic scars tend to have collagen in a wavy, regular pattern, whereas keloids have no distinct pattern of collagen.
Cryosurgery may reduce the size of a keloid, which can make the injections more effective. Dermatologists have found that patients who have three or more cryosurgery treatments tend to get the best results. Laser treatment: This can reduce the height and fade the color of a keloid.
If left untreated by a dermatologist, a keloid scar can get larger and more visible, so it's important to get treatment earlier, rather than later. And thanks to its texture, it's not easily covered up with concealer, making it even more crucial to treat it as soon as possible.
Keloids can take 3–12 months to develop after the original injury. They start as raised scars that can be pink, red, purple, or brown and typically become darker over time. The appearance can depend on the location of the keloid, as well as the person's skin tone.
Appearance: Piercing bumps commonly take the form of tiny, raised, red or pink bumps near the piercing site. They might itch or hurt, and they might discharge. Keloids, on the other hand, are typically larger, thicker, raised scars that do not stop at the site of the original injury or wound.
