Hypertrophic scars are actually directly related to a scar-prone constitution, and generally, when such scars occur, they are divided into several types. The first type is caused by regressive changes, and the outcomes in this situation are generally quite ideal. However, improvement in these cases usually needs to be tailored to the specific circumstances. If the issue with hypertrophic scars is more pronounced, it can be addressed with laser surgery to achieve effective treatment. Of course, it requires specific analysis; not every issue in this regard necessitates intervention, but it should be addressed promptly. Moreover, if a scar-prone constitution persists, it might have some direct impacts. Decisions on improvement can be made based on the specific size of the scar area.

How to remove keloids?

The formation of keloids is largely related to one's inherent scarring constitution. Some patients are not prone to keloids but can still develop them due to particularly deep or large wounds. Additionally, keloids can form on the chest or shoulders after repeated occurrences of folliculitis. Currently, there are not many treatments for keloids. For larger keloids, medication can be used locally to gradually soften and reduce their size. For smaller areas, cosmetic surgical methods can be employed for removal, although this does not guarantee prevention of recurrence. Once keloids appear, they are mostly irreversible. If the keloid grows rapidly, treatment can also be sought at nuclear medicine departments, where nuclear radiation therapy is used.

What should not be eaten with hypertrophic scars?

Hypertrophic scars, in themselves, result from constitutional issues, meaning they are tied to an individual's physical condition and have certain hereditary elements. This condition significantly affects appearance, and certain dietary items can further irritate hypertrophic scars. Thus, it is recommended to avoid certain stimulating foods such as bamboo shoots, beef, crucian carp, and seafood, as these can impede the healing of hypertrophic scars. Moreover, if symptoms are pronounced, or if irritation is prominent, it is also advisable to avoid spicy foods, alcohol, and smoking. Such irritants can notably aggravate the skin, potentially leading to localized scar sensitivity.

The difference between hypertrophic scars and keloids

In a strict sense, hypertrophic scars and keloids are similar in their pathogenesis. For hypertrophic scars, the typical presentation is localized overgrowth at the scar site, which means that there is an overgrowth during the wound healing process, resulting in a relatively large and numerous scar. Keloids represent a more severe condition where there is a localized raised scar on the wound, which can be significantly large, sometimes resembling a bug on the surface of the scar. They are more likely to occur in areas like the neck, behind the ears, and under the earlobes. For the treatment of hypertrophic scars and keloids, if the patient has a predisposition to scarring, considerations include early intervention during wound suturing and healing, such as injection of medications or radiation therapy.

How to repair hypertrophic scars?

In cases of trauma or injury, it is very easy to develop hypertrophic scars. Generally, the size and depth of the wound are related factors. Scars often present with symptoms like redness, itching, and raised hard areas. There are mainly two approaches to treat this type of scar. The first method involves improvement through medications, using topical drugs or local injections to help eliminate hypertrophic scars. The second method involves surgical approaches, such as laser surgery, which is a common method of repair. Generally, local burning from the procedure can achieve certain effects. Of course, after using laser surgery, a specific recovery period is required. During this period, it is necessary to avoid infections to aid in the repair of hypertrophic scars.

How to eliminate hypertrophic scars?

For the elimination of hypertrophic scars, one can apply anti-scarring ointment to the surface early after surgery. If the patient indeed has a scarring constitution, at the end of the surgery, it is advisable to inject medications into the subcutaneous area or within the wound tissue to prevent excessive or abnormal scar proliferation. If necessary, radiotherapy can be applied; under the effect of X-rays, it can effectively prevent the abnormal proliferation of scar tissue and the abnormal and excessive growth of fibroblasts. If there is already hypertrophic scarring, one might consider excising the hypertrophied scar tissue and re-suturing the wound.
