Study Description

Hyperpigmentation is a common skin condition in which the colour of the skin becomes darker. These changes result from an excess of melanin production, distribution, or transport which can be caused by various internal and external factors such as genetic predisposition, hormonal changes, inflammation, acne, ultraviolet (UV) exposure.

Typical hyperpigmentation disorders include post-inflammatory hyperpigmentation, melasma and solar lentigines.

This open, single-centre, three-arm study is carried out with a new cosmetic formulation developed with the aim of acting on facial hyperpigmentation and used under normal conditions of use with before/after comparisons.

This clinical trial is conducted in accordance with the protocol, the HELSINKI declaration (1964) and subsequent amendments, and/or the International Council on Harmonization (ICH) Good Clinical Practices (GCP)/ and in compliance with applicable regulatory requirements.

Statistical Analysis:

  • Efficacy Analysis: in each group, the quantitative parameters are analyzed using a mixed-effect model. This model includes Time and baseline as fixed effects. Patient are added as random effect. The comparisons between post-baseline time-point and baseline are performed whatever the interaction results using a Dunnett adjustment. Degrees of freedom for the comparisons are approximated by the Kenward-Roger method.

  • Safety Analysis: no statistical analysis will be performed on safety. The data are presented descriptively.

Categorical data are summarized using the number and percentage of patients in each category. Continuous data are summarized using the arithmetic mean, Standard Deviation (SD), Q1, Q3, minimum, median and maximum values.

Regarding the sample size determination, there was no formal calculation. A number of 20 patients in each group was considered sufficient to meet the study objective.
