A hypertrophic scar is a scar that becomes puffy, swollen, and red, causing it to stand out from the surrounding skin. These types of scars are sometimes confused with keloids, scars that look alike but behave slightly differently. There is no particular reason why some injuries cause a worse scar than others; Hypertrophic scars form when something goes wrong with the healing process, and this can happen in any number of circumstances.
Unlike a keloid, a hypertrophic scar will not grow or spread. Once the scar covers the wound, it will remain the same size and, in many cases, will resolve over time. After several years, a hypertrophic scar may shrink considerably and also lighten in color, making it less visible. For this reason, people who want to get rid of their scars are sometimes advised to wait and see if the scars dissolve on their own, rather than undergo medical procedures to address the problem.
The material within the scar is collagen generated by the body trying to heal the underlying injury. Hypertrophic scars generally feel firm to the touch and may be sensitive to changes in temperature or texture. People may want to get rid of them for a variety of reasons, ranging from believing the scar is unsightly to contractures that restrict movement, caused by scarring along joints and in other inconvenient areas.
Conservative treatment approaches are usually used first to manage a hypertrophic scar. The doctor may start with steroid injections to reduce the scar, or recommend natural remedies such as tea tree oil, salt, or vitamin E oil applied topically to reduce the size of the scar. If these measures do not work, surgery can be used to remove the scar or reduce it. Laser is one of the preferred methods, although there are other options.
Dermatologists and plastic surgeons can provide treatment for hypertrophic scars and keloids. Plastic surgeons often have access to the latest technology and research, and can offer a more pleasing result for those with greater cosmetic concerns.
The chance of forming raised scars after injury appears to be reduced by wearing pressure bandages on injuries. Applying pressure to the site can inhibit scar formation, making a hypertrophic or keloid scar less likely. Patients should be careful how they use pressure as it may unintentionally damage their desire to avoid scarring. It's a good idea to discuss concerns about scarring with a doctor and follow their treatment recommendations. Pressure compresses may be recommended if a scar is surgically removed to prevent a recurrence.
