Scars are formations of epithelial tissue that is torn as a result of an injury or accident. As we well know, this event causes the skin to be restored and it does so through what are called young fibroblasts, which cover the wound or injury with a tissue that has the appearance of muscles. That is why scars generally have a different appearance and texture than skin, since in reality it is not tissue or skin as such, but a resource that our body uses for these cases that has different characteristics. . In this way, it can be said that scars are obvious alterations of the dermal or skin appearance, which are the result of a tear generally caused by an injury or accident,
Scars are one of the most common types of injuries or marks in humans. In fact, its appearance is nothing strange. On the contrary, most people have at least one of them. There are several ways in which a person has a scar, although most are the result of an injury to the dermal tissue or the skin. Also, scars are not the same in all cases. Its final appearance is due to the type of skin of the person, the degree or severity of the injury and, above all, the process of caring for and healing it. That is why the classification of scars is carried out mainly from the type of injury that the occasions and particularly by the appearance or type of tissue that they leave as a final result. That is, the scar itself.
Types of scars, hypertrophic
Types of scars:
Hypertrophic and keloid scars:both types are the most common. These are scars that are characterized by an excessive accumulation of dermal tissue in the affected area, mainly fibroblasts, collagen and elastin. The difference between both types of scars is that when the mark is of greater extension, both in length and width, than the injury that caused it then we speak of a keloid type scar. Otherwise, in both cases the same process occurs. Most of the time this type of scars appear due to surgical interventions or accidents. However, they can also appear as a result of small events that do not represent any seriousness or pain at the time of suffering. Evidently,
Atrophic scars: this type of scar is the one that occurs after the destruction of the so-called dermal collagen. This means that these scars appear after the injury has destroyed the skin, not being able to recover it completely, not even trying to create regenerative tissue that one or close the wound. Therefore, the best examples of these types of scars are the marks left by acne or diseases such as chicken pox, measles or rubella. Also, some consider that stretch marks are scars of this type, although there is no agreement on this.
Hyperpigmented scars: as the name implies, this type of scars has as its main characteristic a high amount of pigmentation in the affected area. These are generally superficial marks that could be caused by any event. They do not usually generate lumps or scars with very prominent textures, but only pigment the skin producing a visual mark.
Hypopigmented scars: contrary to the case previously presented, scars of this type are also characterized by pigmentation of the skin, although in this case they are not of a much darker skin tone but, on the contrary, of a lighter color. Therefore, these types of scars have an appearance much more similar to that of spots and not so much to that of a scar. These types of marks usually appear due to skin diseases or infections and very rarely due to traumatic events or injuries caused by accidents.
