Effectiveness and Safety of Cellbooster Shape in Healthy Subjects

3. června 2026 aktualizováno: Suisselle

A Prospective, Open-label Study on the Effectiveness and Safety of Cellbooster® Shape (Stabilized Booster Complex Using CHAC Technology) on Healthy Subjects.

SUISSELLE has developed a CE marketed (2021) HA-based superficial epidermis/dermis injection filler and skinbooster product, Cellbooster® Shape (CBS). CBS is produced using patented CHAC Technology. It consists of non-crosslinked HA with L-Carnitine and vitamin C. The device is particularly designed for reducing local puffiness by improving microcirculation and hydration.

The current post-market clinical investigation is designed to evaluate the efficacy and safety of CBS. For this purpose, healthy subjects with signs of skin aging in the face will receive a 3-session treatment and will be followed-up over 70 days after the initial injection session.

Several objective measurements of skin quality will be performed with different instruments allowing to assess skin volume, skin elasticity, skin hydration, and skin microcirculation. Subjective clinical improvement will be evaluated, as well as subject and investigator satisfactions.

The safety of the injections will be assessed by collecting the Injection Site Reactions (ISRs) and Adverse Events (AEs).

Detailní popis

A prospective, open-label study on the effectiveness and safety of CellBooster® Shape (stabilized booster complex using CHAC technology) on healthy subjects. Single centre, prospective, open, before/after treatment, non comparative clinical investigation.

Primary objective:

To evaluate CellBooster® Shape (CBS) effectiveness on clinical Global Aesthetic Improvement, using the Global Aesthetic Improvement Scale (GAIS) evaluated by the investigator at D42.

Secondary objectives:

- To evaluate CBS effectiveness on clinical Global Aesthetic Improvement, using GAIS evaluated by the investigator at D70.

To evaluate CBS effectiveness on clinical Global Aesthetic Improvement, using GAIS evaluated by the subject at D42 and D70.

  • To evaluate the satisfaction of the injectors with CBS treatment using a subjective evaluation questionnaire after each injection session (D0, D14 and D28).
  • To evaluate the satisfaction of the subjects with CBS treatment using a subjective evaluation questionnaire at D42 and D70.
  • To illustrate CBS aesthetic effect through 2D photographies throughout the study period.
  • To evaluate CBS effectiveness of the improvement of skin quality by measurements of skin volume, microcirculation, elasticity, and hydration.
  • To evaluate CBS safety throughout the study period by ISRs evaluated by subject and investigator and AEs collection.
