Inclusion criteria

* Intent to undergo treatment of depressed acne scars * Presence of 5-20 scars with a diameter of up to approximately 4 mm within the treatment area * Similar type, size and number of scars on both cheeks * Men or non-pregnant, non-breast feeding women * Fitzpatrick skin type I-IV * Signed and dated informed consent to participate in the study

Exclusion criteria

* Presence of more than 3 scars per cheek (within the treatment area) of the following types: icepick scars or atrophic acne scars with a diameter of \> 4 mm. * Active acne with inflammatory component * Use of per oral or topical (facial) substances containing retinoids, bensoyl peroxide, alpha-hydroxy acid at concentrations above 10%, beta-hydroxy acid at a concentration above 2%, or antibiotic treatment for active acne within 4 months before treatment * Use of isotretinoin within 6 months before treatment * Post-surgical scars in the treatment area * Previous tissue augmenting therapy or contouring with permanent filler or fat-injection in the treatment area * Previous tissue augmenting therapy, contouring or revitalisation treatment with Calcium Hydroxyapatite (CaHa), or Poly L-Lactic Acid (PLLA), in the treatment area within 24 months before treatment * Previous tissue augmenting therapy, contouring or revitalisation treatment with non-permanent filler such as hyaluronic acid (HA) or collagen in the treatment area within 12 months before treatment * Previous tissue revitalisation treatment with neurotoxin, laser or light, mesotherapy, chemical peeling or dermabrasion in the treatment area within 6 months before treatment * Previous surgery including aesthetic facial surgical therapy, liposuction, or tattoo in the treatment area * Any medical condition that, in the opinion of the treating Investigator, would make the subject unsuitable for inclusion (e.g. a chronic, relapsing or hereditary disease that may interfere with the outcome of the study)
