Brief Summary

Acne scars represent a frequent complication of moderate/severe acne and may negatively impact on psychosocial and physical well-being of acne patients. Several types of acne scars have been classified and the same patient is likely to have more than one type. Each type can be treated with varying degrees of success. The main acne scars are the following: Atrophic or Depressed Scarring:

  • Ice pick: An ice pick scar has a wide shaft that narrows down to the tip. It resembles a hole that's wide at the top and narrows to a point as it goes deeper into the skin. Such an indentation is common and one of the most challenging scars to heal. This scar is more frequent on forehead and upper cheeks, where skin is thinner.
  • Rolling: These scars are typically found on the lower cheeks and jaw, where skin is thicker. The indents have sloping edges that makes the skin look uneven and wavy.
  • Boxcar: Boxcar scars are indents that have sharper edges. Those edges go down deep into the skin. These scars are common on the lower checks and jaw.

Outcome Measures

Primary Outcomes (2)

  • Change from Baseline of Skin Roughness and flaccidity at 30 days and at 120 days post-injection

    Visual score from 1 (milder scarring) to 4 (severe scarring) (Goodman and Baron Grading Scale of Postacne Scarring)

    Day 0, Day 30, Day 120

  • Change from Baseline of Skin's surface Profilometry at 30 days and at 120 days post-injection

    A measurement of the skin surface affected by acne scars is taken thanks to Primos compact portable device (GFMesstechnik); Primos software is able to measure skin principal profilometric parameters in vivo or on skin replicas, the software compares directly the different images obtained at the times foresee by the protocol.

    Day 0, Day 30, Day 120

Secondary Outcomes (2)

  • Efficacy questionnaire

    Day 120

  • Treatment tolerance questionnaire

    Day 120

Study Arms (1)

HCC_45 treatment group

EXPERIMENTAL

Treatment of acne scars of the face by using a subcision+injection technique: the needle (25 G) or cannula (25 G) (wider areas are treated with the cannula) is inserted into the skin and made to move with a back-and-forth motion in order to detach scar collagen bundles. Then 1 syringe (2 ml) of HCC\_45 is injected. Day 0: Information and consent form provided, Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. First treatment of HCC\_45 (refer to study protocol). Day 30 (1 month after day 0): Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. Second treatment of HCC\_45 (refer to study protocol). Day 120 (4 months after day 0): Clinical assessment, Digital clinical pictures, Instrumental assessment, Profilometry measurement. NO treatment, Self-evaluation questionnaire.

Device: HCC_45

Interventions

HCC_45DEVICE

Dosage form: HCC\_45 is a resorbable medical device 2 ml non-pyrogenic pre-filled syringe, containing 2 ml of hyaluronic acid for intradermal use. The principal component of the medical device is Hyaluronic Acid of non-animal origin, produced by bacterial fermentation.
