Potential Scaring difficulties

Hypertrophic scars

Hypertrophic scars are raised, red and formed as a result of excessive production of Type I collagen during the healing of skin lesions. These scars often appear within weeks/months of the injury and reach their maximum size and thickness relatively early on.

Hypertrophic scars*

How are they caused?
The healing process is disrupted which induces an imbalanced production of Collagene Type I and Collagene Type III. Indeed, instead of producing a flat, smooth scar, the body produces an excessive amount of collagen type I, resulting in a raised, lumpy, reddish scar. Contrary to Keloid scars, they stay within the boundaries of the original wound and do not extend beyond it.
Factors such as genetics, the type and location of the injury, and an overactive healing response contribute to their development. The risk of developping a hypertrophic scar therefore varies accross individuals, as well as for a given individual depending on its surronding environment.

What do they look like?
Hypertrophic scars are visibly elevated above the surrounding skin, creating a raised or thickened texture.
These scars often appear red or pink, making them more noticeable than the surrounding skin.

Are there any associated symptoms?
Hypertrophic scars may be accompanied by persistent itching, which can be bothersome and contribute to discomfort. Some individuals may experience tenderness or pain at the site of the hypertrophic scar, especially during the early stages of its formation.

It’s important to note that while these symptoms are characteristic of hypertrophic scars, individual experiences may vary. Seeking medical advice is recommended for proper diagnosis and appropriate management of hypertrophic scars.

Keloid Scars

keloids scars are raised scars that go beyond the original wound, orming due to an abnormaly extended and exaggerated inflamatory phase during the healing process. They can be shiny and smooth and of variable color. Keloids might cause itching, tenderness, or pain.

Keloid Scars*

How are they caused?
The formation of keloids involves an abnormal response to the healing process, where there is an overproduction of collagen which can grow outside the boundaries of the original wound.
Factors like genetics and skin tension play a role in their development. The risk of developping a keloid scar therefore varies accross individuals, as well as for a given individual depending on its surronding environment.

How they look like?
Keloid scars have a raised and overgrown appearance, and unlike hypertrophic scars, extend beyond the original wound. These scars often have a shiny and smooth surface, differentiating them from the surrounding skin, and can vary in color from pink to dark brown.

Are there any associated symptoms?
Keloid scars may cause persistent itching, leading to discomfort and some may experience tenderness or pain at the site of the scar.

It’s important to note that while these symptoms are common, individual experiences may vary. Seeking medical advice is recommended for a proper diagnosis and appropriate management of keloid scars.

Atrophic scars

Atrophic scars are characterized by a loss of tissue and extracellular matrix at the site of the wound or skin, resulting in a depression or hole in the skin. These scars often appear flat and may be lighter in color than the surrounding skin.

Atrophic scars**

How are they caused?
Atrophic scars occur when there is insufficient collagen (both Type I and Type III) production during the wound healing process. This scars can be caused by conditions such as acne, surgical incisions, or injuries, and they may be more common in individuals with a genetic predisposition to problematic scars. The risk of developping a atrophic scar therefore varies accross individuals, as well as for a given individual depending on its surronding environment.

How they look like?
Atrophic surgical scars appear sunken or depressed compared to the surrounding skin. They are characterized by a loss of tissue volume in the scar area.

Are there any associated symptoms?
Atrophic surgical scars themselves typically do not cause symptoms such as pain or itching.

It’s important to note that while these symptoms are common, individual experiences may vary. Seeking medical advice is recommended for proper diagnosis and appropriate management of hypertrophic scars.

Scarring symptoms

Scars may manifest a diverse array of symptoms concerning their appearance, functionality, and sensory perceptions. Pain and pruritus (itching) stand out as the predominant symptomsencountered in clinical settings, often severe and persisting for an extended duration post-wound healing. During the healing process, it’s also common to experience a loss of sensation in the area of the scar.

Scarring symptoms***

Pain and pruritus (itching) are common symptoms experienced during the scarring process:
– Pain can result from nerve damage during injury or surgery, inflammation, or tension on the skin.
– Pruritus, or itching, can occur as a result of the healing process and the formation of new tissue.
– La perte de sensations

Both pain and itching can be exacerbated by factors such as dryness, tight clothing, and environmental irritants. While these symptoms often diminish over time as the scar matures, they can persist for months or even years in some cases. Various treatment options, including topical creams, silicone gel sheets, massage therapy, and laser therapy, can help alleviate pain and itching associated with scars.

Besides that, loss of sensation in the area of the scar can occur due to damage to nerve endings during the initial injury, surgical procedure, or inflammation. The extent of sensory loss can vary depending on the severity of the wound and the individual’s healing process. In some cases, sensation may return gradually as the nerves regenerate and the scar matures. However, in other instances, particularly with deeper wounds or surgical procedures, permanent loss of sensation may occur.

It’s important to note that while these symptoms are common, individual experiences may vary.It is recommended to consult a doctor for a solid diagnosis and proper management of the symptoms associated with healing.
