Evaluation of Acne Scarring and the Surrounding Skin Using the Global Aesthetic Improvement Scale [ Time Frame: 36 weeks ]
Percentage of improved subjects at 36 weeks after first treatment session assessed using Subject GAIS. Scale range is Worse, No Change, Somewhat Improved, Much Improved and Very Much Improved. Alternatives Somewhat Improved to Very Much Improved are considered an improvement, i.e. a better outcome.
Secondary Outcome Measures :
Evaluation of Skin Quality and Overall Satisfaction Using a Subject Satisfaction Questionnaire [ Time Frame: 36 weeks ]
Percentage of subjects satisfied with the overall appearance of the face at 36 weeks after first treatment session. Scale range is Very dissatisfied, Somewhat dissatisfied, Neither satisfied nor dissatisfied, Somewhat satisfied and Very satisfied. Alternatives Somewhat satisfied to Very satified are considered a better outcome.
Evaluation of Acne Scarring Using the Scale for Acne Scar Severity (SCAR-S) [ Time Frame: 36 weeks ]
Percentage of subjects improved at 36 weeks after first treatment session assessed using SCAR-S. Scale range is Very severe, Severe, Moderate, Mild, Almost clear and Clear. The alternative Clear is considered the best outcome. Improvement is considered to be at least one step improvement on the scale toward the alternative Clear.
Assessment of Local Tolerability After Treatment [ Time Frame: 14 days ]
Number of subjects reporting anticipated injection-related reactions after treatment
Adverse Event Reporting During the Study [ Time Frame: 36 weeks ]
Number of subjects reporting at least one adverse event (assessed as unrelated or related to treatment)

Concomitant anticoagulant therapy and therapy with inhibitors of platelet aggregation (e.g. aspirin or other nonsteroidal anti-inflammatory drugs [NSAIDs]), Omega-3 or vitamin E seven days before the injection, or a history of bleeding disorders.

Previous hypersensitivity to HA.
Previous hypersensitivity to lidocaine or other amide-type anaesthetics.
Concomitant treatment with chemotherapy, immunosuppressive agents, immunomodulatory therapy (e.g. monoclonal antibodies), systemic or topical (facial) corticosteroids within 3 months of the baseline visit. (Inhaled corticoids are not an exclusion criterion).

Previous surgery in the treatment area.
Nicotine use within 6 months before the baseline visit.
Pregnancy or breast feeding.
Participation in any other clinical study within 30 days before inclusion.

Other condition preventing the subject from entering the study in the investigator's opinion, e.g. subjects not likely to avoid other facial cosmetic treatments, subjects anticipated to be unreliable or incapable of understanding the study assessment or unrealistic expectations of treatment result.
