简要总结
The objective of this study is to evaluate the efficacy, cosmetic acceptability and improvement of the stigmatization of the tested product (2039125 03) used bis in die (BID) for 3 months in adult patients suffering from mild to moderate melasma, or mild to moderate acne induced post-inflammatory hyperpigmentation, or solar lentigo.
详细描述
Hyperpigmentation is a common skin condition in which the color of the skin becomes darker. These changes result from an excess of melanin production, distribution, or transport which can be caused by various internal or external factors such as genetic predisposition, hormonal changes, inflammation, acne, ultraviolet (UV) exposure.
Typical hyperpigmentation disorders include post-inflammatory hyperpigmentation, melasma and solar lentigos.
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.

结局指标
主要结局
IGA score for patients with melasma or post-acne post-inflammatory hyperpigmentation (PIHP)
时间窗: from baseline to Day84
the hyperpigmentation is measured on a scale from 0 (cleared, almost cleared) to 3 (Severe (Markedly darker than the surrounding normal skin))
modified Melasma Area Severity Index (mMASI) for patients with melasma
时间窗: from baseline to Day 84
The mMASI is calculated using 3 components: four regions of the face (forehead, right malar, left malar and chin); area of involvement for each region (using a scale from 0 to 6); darkness compared to the surrounding normal skin for each area (evaluated using a scale from 0 to 4)
Post-Acne Hyper Pigmentation Index (PAHPI)
时间窗: from baseline to Day 84
The PAHPI total score is the sum of all 3 weighted scores: medial lesion size (from 2 \[\< 3mm\] to 8 \[\> 10 mm\]), median lesion intensity (from 3 \[Slightly darker than surrounding skin\] to 9 \[Significantly darker than surrounding skin\]), and number of lesions (from 1 \[1-15\] to 5 \[\> 60\]). Total score ranges from 6 to 22.
solar lentigo pigmentation scale
时间窗: from baseline to Day84
the solar lentigo pigmentation scale evaluates the pigmentation using the following scale: form 0 (no pigmentation) to 10 (brown+).
次要结局
- colorimetry measurements(from baseline to Day84)
