The Suitability of Tience® for Treating Acne Scars

The Suitability of Tience® for the Treatment of Acne Scars

This is an open-label, single-center, split-face, pseudo-randomized clinical trial designed to evaluate the efficacy and safety of a human-derived, cell-free adipose tissue derivative (Tience® ), for treating moderate to severe acne scars. Participants will receive three treatment sessions over a three-month period: on Day 0, Day 30, and Day 90. Treatment will be administered via injections to acne-scarred areas on one side of the face. The untreated side will be treated after the follow-up period. Outcomes will be evaluated over a twelve-month period using investigator clinical assessments, patient self-evaluation and VISIA skin analysis system to monitor changes in scar severity and overall skin quality.

Tience®, a human adipose tissue derivative, is intended to be used in the human body for its original purpose to supplement and replace local extracellular matrix deficiencies in soft tissue, including skin. Tience provides a temporary conductive environment into the injured area. This facilitates the ability of local cells to re-populate the damaged soft tissue and skin area, thereby enabling the deposition of extracellular matrix and repair of the tissue. Tience is authorized for treatment of wounds, scars and soft tissue defects.

The purpose of this study is to determine whether the product is suitable for the treatment of acne scars, and to collect safety data on the use of Tience® in this indication.

Inclusion Criteria: healthy volunteers aged 18-40 years who have at least 3-year- old acne scars on their cheeks.
