Scars from self-harm

Scars from self-harm are permanent skin changes resulting from intentional tissue damage, most often by cutting the skin with a sharp object. They include both superficial linear scars and deeper, hypertrophic, or atrophic tissue defects. The process of their formation is a consequence of the physiological healing of a wound, which—depending on the depth of the dermal damage—leads to permanent remodeling of collagen fibers. Such scars are most commonly located on the forearms, thighs, and calves. Beyond the dermatological aspect, they also pose a psychological and social problem, therefore their treatment requires an interdisciplinary approach, encompassing both skin therapy and, if necessary, psychiatric or psychological support.

Self-harm scars – what do they look like

The clinical appearance of self-harm scars depends on:

the depth of skin damage,
the frequency of injury in the same area,
genetic predisposition to forming hypertrophic scars or keloids,
the normality of the healing process (infections, wound dehiscence).

The most commonly observed are:

numerous, parallel linear scars of uniform length and depth,
changes in the mature stage – light, pearly, slightly sunken skin bands,
in the fresh phase – erythematous, firm, raised above the skin surface lines,
atrophic scars – with a thin, thinned structure,
hypertrophic scars – thickened, dense, sometimes painful when pressed.

In dermoscopic examination, there is visible disorganization of the collagen network and lack of normal skin architecture. Histologically, there is a dominance of chaotic arrangement of type I collagen fibers, a reduced number of skin appendages (hair follicles, sweat glands), and a disrupted vascular network.

It is worth noting that self-harm scars often have a multifocal and symmetrical nature, which distinguishes them from accidental injuries.

Scars from self-harm – do they disappear?

A scar is a permanent form of repair for damaged skin. Biologically speaking:

there is no complete regeneration of the dermis,
the collagen structure remains altered,
skin appendages do not regenerate.

The scar maturation process usually takes 6–18 months and includes:

the inflammatory phase,
the proliferative phase (intense collagen synthesis),
the remodeling phase.

During this time:

scars may fade,
their elevation decreases,
elasticity improves.

However, complete disappearance of the scar is not possible if the damage involved the dermis. An exception is very superficial damage limited only to the epidermis, where healing without a permanent mark is possible.

Factors influencing scar visibility:

the patient's age (younger skin heals more intensely but more often forms hypertrophic scars),
skin phototype,
location (areas with high skin tension heal worse),
genetic predisposition to keloids.

The realistic goal of therapy is to reduce visibility, improve structure, and even out the color, rather than complete removal of the mark.

Scars from self-harm – how to remove

The therapeutic approach depends on the type and age of the scar. In aesthetic medicine and dermatology, methods are used to stimulate controlled collagen remodeling and improve skin structure.

1. Fractional Laser Therapy (ablative and non-ablative)

causes microthermal damage,
stimulates neocollagenesis,
improves skin density and tension.

The best effects are observed in atrophic and linear scars.

2. Microneedle Radiofrequency

combines microneedling with RF energy,
leads to controlled contraction of collagen fibers,
improves skin structure and reduces the visibility of depressions.

In clinical settings, microneedle radiofrequency is used, among others, at Ambasada Urody Clinic & Spa.

3. Regenerative Therapies

platelet-rich plasma (PRP),
regenerative mesotherapy,
tissue stimulators (e.g., calcium hydroxyapatite, polynucleotides).

Their goal is to improve skin quality and support scar remodeling.

4. Laser Treatment for Pigmentation

In cases of persistent erythema or post-inflammatory pigmentation, vascular and pigment lasers are used.

5. Supporting Treatments

medical peels,
light therapy,
individually tailored topical pharmacotherapy (retinoids, medical silicone).

Choice of Therapy

The effectiveness of treatment depends on:

the age of the scar,
its depth,
the number of changes,
patient expectations.

The best results are achieved with combination therapy, conducted in treatment series, with appropriate breaks for the collagen remodeling process (4–8 weeks).

In the case of self-harm scars, a holistic approach is particularly important. From a medical perspective, reducing the visibility of these marks is possible and predictable. However, in many cases, parallel psychological support is also a crucial component of the therapeutic process.
