HOW TO TREAT ACNE SCARS.


The Rejuvapen® treatment can provide drastic results improving the appearances of the scars. The micro needles of the Rejuvapen® create new collagen and elastin to be generated and deposited called collagenesis, however the added benefit of new capillary growth is also a result which can improve blood supply to the area which helps create healthier existing skin as well as provide a healthy foundation for the new skin. The physical nature of “skin-needling” breaks up this fibrous and uneven scar tissue and stimulates 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 Rejuvapen® keeps the epidermis integrity full intact while treating the area which quickens healing time and causes less pain.

The Rejuvapen adjustable needles penetrate a controlled depth into the dermis.  The dermis develops multiple microbruises, which start a cascade of growth factor release and collagen production.  Punch biopsy histology demonstrates thickening of the skin with dramatic increases in new collagen and elastin fibers .  As collagen is deposited, the skin texture improves.  Results are initially seen in six weeks and full effect will take three months to develop.

Scars are areas of fibrous tissue 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 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. 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.”


How many treatments?

Your medical professional should consult on medical treatment. While each patient is different and conditions will vary, the typical treatment regimen will consist of 5-6 treatments.

TREATMENT TYPEMECHANISM-INDICATIONSIDE EFFECTS
Chemical PeelBest results with macular scars. Only variable results with icepick and rolling scars.Temporary hyper-pigmentation or irritation.
DermabrasionCompletely removes the epidermis to the papillary or reticular dermis. Will treat icepick and rolling scars.General anesthesia and infection risks. Significant patient downtime. Darker skin may become discolored and blotchy.
MicrodermabrasionRemoves outer layer of the epidermis. Does not treat deep scars.Only rare complications.
Needle DermabrasionLeaves epidermis largely intact. Full effect seen after 6 weeks as mechanism of action is enhanced collagen production.Lowest risk of post inflammatory hyper pigmentation than the other procedures.
Fractional Laser TreatmentAblative is more effective than non ablative. Quantifiable improvement of 40-80% in scar depth.Patient must stop isoretinoin. Dark skin is at risk of post inflammatory hyper pigmentation. Hyper pigmentation using conventional CO2 laser is 36% (Alster and West, 1996)
 

For Acne Scar Treatments there are many treatments for acne scars, each with characteristic side effects. For most treatments, the principle treatment side effect is postinflamatory hyperpigmentation which is most pronounced in darker skin types Post inflammatory hyperpigmentation may result from dermabrasion, chemical peels and Fraxel & laser resurfacing.
