DERMAPEN ACNE SCARS
Dermapen acne scars are areas of fibrous tissue (fibrosis)
that replace normal skin after injury. A scar results from the biological
process of wound repair in the skin and other tissues of the body. With the
exception of very minor lesions, every wound (e.g. after accident, disease,
surgery) results in some degree of scarring. Scar tissue is the same protein
(collagen) as the tissue that it replaces, but the fiber composition of the
protein is different. Instead of a nice “basket weave” formation of fibers, the
collagen in scar tissue is aligned in a single direction resulting in a
pronounced and thicker appearance. Acne treatments for most are long term and
can result in scarring. There are multiple causes of acne including hormone
dysfunction, allergies, environmental factors and nutrition deficiencies. Acne
scars result after skin follicles become blocked by excessive oils and the
physiology of keratin and old skin cells trigger an inflammatory response
reaction. The skin will attempt to heal and the scar tissue results as the
collagen becomes deformed and thickens. Acne scars are categorized as being
“ice- pick”, “rolling” or “boxcar.”
The Dermapen can provide results for improving the
appearances of the acne scars. The physical nature of “skin-needling” can break
up fibrous and uneven scar tissue and encourage the growth of new tissue.
Currently there are ablative and non-ablative treatments offered, which can
damage the epidermis and evaporate the skin leading to thinner epidermis
problems. The Dermapen keeps the epidermis integrity fully intact, which
quickens healing time and causes less pain.
How many sessions
Your medical professional should consult you on best course
of action for skin conditions. While each patient is different and conditions
will vary, the typical regimen will consist of 5-6 sessions.
Acne Scars
Acne scars are created by the wound healing process
occurring after the acute process of inflammation, follicular rupture and
perifollicular abscess formation.
The resulting acne scars may be atrophic or hypertrophic
(Fabbrocini et al., 2010). Approximately
80% of scars are atrophic associated with a net loss of collagen during the
matrix remodeling process. A minority of
scars are hypertrophic or have keloid formation. Atrophic scars are classified as:
Ice pick (70%) – These are the narrow < 2mm punctiform
depressions with a “V” cross-section. Boxcar (20%) – These are round or oval
scars with well-established vertical edges with a wide base and a “U”
cross-section. Rolling scars (10%) – These wide > 4 mm scars have an “M”
cross-section and give an undulating appearance to the skin.
