If the skin z. For example, injuries caused by an accident or surgery leave scars behind. Ideally, at the end of the scar formation process, there is only a pale outline to be seen, but unfortunately that is not always the case. Often, unsightly scars are created.
Scars - how are they created?
The skin is built up in three layers, the epidermis, the dermis and the subcutis. If an injury cuts through not only the epidermis, but also the underlying skin layer (s), a scar develops. Our organism is unable to renew the destroyed tissue in the same way. Typical properties of the new fabric:
- It is less elastic.
- The function is limited (no hair, sweat glands etc).
Scars may be redder or lighter due to the nature of the new tissue. If such scars are located in well-visible areas, those affected often feel stigmatized and marginalized. In addition, scars can cause feelings of tension and restricted mobility.
Scars - what types are there?
- Scar growths (hypertrophic scars): They are caused by excessive formation of connective tissue. They can be itchy or painful, but they are limited to the original area of injury. A wound exposed to constant movement during healing increases the likelihood that such a scar will form. Scar growths develop within a few weeks after the injury.
- Scar bulges (keloids): These scars are also caused by overproduction of connective tissue. They are thick, arched, often reddened, appear darker than the surrounding tissue and go beyond the original area of injury. The scar structure may have an irregular shape.
- Scar pits (atrophic scars): In contrast to the two types of scars above, scars do not form enough connective tissue to form a "sunken" scar, which is deeper than the surrounding skin, and acne scars are a typical example of this type of scars.
Scars - what affects their appearance?
Various factors influence the development of a scar.
- Age: The skin of older people heals slower. In children or younger people, the skin tends to overreact and produces more connective tissue than required. This results in larger, thicker scars.
- Hereditary factors / skin types: The predisposition to conspicuous scarring can also be hereditary. People of African or Asian descent are more prone to scar growth or growth than Europeans.
- Scar location: Scars that are over or near commonly used areas of the body (eg, shoulder, back, and joints) are subject to greater tension and tend to be more pronounced or more visible than those on less stressed areas of the body.
- Wound Infections / Complications of Wound Healing: Wound infections or inflammation increase the likelihood of conspicuous scarring.
Scars - what can you do about it?
Depending on the nature of the scar, one can choose among a variety of treatment options. These methods include: laser, surgery, injections, cryotherapy, abrasion (abrasion), pressure bandages, silicone gel sheets / pads, and ointments and creams. Which treatment is the right one for a scar is best decided by the doctor.
