TREATMENT FOR ATROPHIC ACNE SCARRING
Patrick Treacy presents the results of a study investigating the efficacy of dermal fillers in the treatment of atrophic acne scarring
ABSTRACT Full title Problems encountered using dermal fillers, particularly calcium hydroxylapatite, as a treatment in acne scarring.
Objectives This article aims to establish the efficacy and safety profile of dermal fillers, especially calcium hydroxyapatite (CaHA) in the treatment of atrophic acne scars.
Methods Twenty-seven subjects with differing degrees of atrophic
A CNE
acne scarring were treated with the CaHA filler over a 12-month period. Thirteen patients were treated with low molecular weight cross-linked hyaluronic acid in a comparative study.
Results Most atrophic acne scars responded well to CaHA dermal filler treatment. Icepick scars were not treated. At 12-month evaluation, 22% of subjects showed a 75% improvement, while 48% showed a 50% improvement. This compared to an average 0% improvement for the hyaluronic acid cohort.
OCCURS IN
approximately 95% of 16–17-year-old boys and 84% of 16–17-year-old girls1
Eleven hyaluronic acid patients (85% of total) showed a 0–25% improvement in treated atrophic scars at 12 months.
Conclusions Dermal fillers, especially CaHA, can provide a safe and efficacious method of treating atrophic acne scars. This compound appears to provide a longer-lasting effect owing to volume replenishment and possible neocollagenesis. The efficacy of hyaluronic acid in repairing atrophic acne scars is not demonstrable.

. . Although the condition usually
resolves by the mid-20s, 1% of men and 5% of women still bear the signs of moderately severe acne scarring at 40 years of age2
. Some studies show
scarring of some degree may affect up to 95% of patients with acne3
. The same
study found that keloidal or hypertrophic truncal scarring were more common in men. This form of scarring is usually treated by using such measures as intralesional steroids, silicone sheeting, or vascular laser treatment. Atrophic scarring will often appear many years later, and can cause great distress in patients during their courtship years4 Affected patients report more social

Background For many years different treatment modalities have been used for the revision of atrophic acne scarring, with varying degrees of success. Many controlled trials have demonstrated that moderate to severe atrophic acne scars can be safely improved through ablative fractional CO2
laser
resurfacing (fractional laser skin resurfacing; FLSR)6
. Although
FLSR is still the most popular therapeutic modality for the correction of acne scars, it is not always effective in all types of atrophic lesions7
