Efficacy Evaluation of a Cosmetic Product for Facial Hyperpigmentation (HYPERPIG)

Evaluation of the Efficacy of a Cosmetic Product for the Reduction of Facial Hyperpigmentation: A Clinical, Subjective, and Instrumental Study

This is a single-center, single-blind clinical study designed to evaluate the efficacy of a depigmenting gel cream through clinical, subjective, and instrumental assessments. A total of 40 female participants, aged 30 to 60 years, will be enrolled and followed for 90 days while using the study product.Participants will be assigned to one of two groups. Group I will include 20 participants with facial hyperpigmentation, including post-inflammatory hyperpigmentation and solar lentigines, representing Fitzpatrick skin phototypes I to VI, with at least one participant from each phototype. Group II will include 20 participants with moderate or greater melasma, as assessed by the modified Melasma Area and Severity Index (mMASI), representing Fitzpatrick skin phototypes II to V.

The study aims to evaluate the product's effectiveness in reducing facial hyperpigmentation and improving skin appearance over the treatment period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Facial Hyperpigmentation Assessed by Chromameter (L* Parameter)
Time Frame: Baseline (Day 0), Day 30, Day 60, and Day 90
Evaluation of the efficacy of the investigational product in improving facial hyperpigmentation in participants with post-inflammatory hyperpigmentation, solar lentigines, and melasma through colorimetric measurements obtained using the Chromameter® device. Changes in the L* parameter will be assessed over time, with higher values indicating skin lightening.
Baseline (Day 0), Day 30, Day 60, and Day 90

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the Number of Facial Pigmented Lesions Assessed by VISIA® Imaging System
Time Frame: Baseline (Day 0), Day 30, Day 60, and Day 90

Evaluation of the efficacy of the investigational product in improving melasma in participants diagnosed with melasma using the Modified Melasma Area and Severity Index (mMASI). The mMASI assesses melasma severity across four facial regions: forehead, right malar region, left malar region, and chin, weighted according to their proportional facial areas. Scores range from 0 to 24, with 0 indicating no melasma and 24 indicating the most severe melasma. Higher scores indicate worse disease severity, and lower scores indicate improvement. The mMASI score is calculated using the formula: mMASI = 0.3(AF×PF) + 0.3(AMD×PMD) + 0.3(AME×PME) + 0.1(AM×PM).

Time Frame: Baseline (Day 0), Day 30, Day 60, and Day 90
Evaluation of the impact of treatment on the quality of life of participants with melasma using the Melasma Quality of Life Scale (MelasQoL). The MelasQoL assesses the impact of melasma on daily life and well-being using ordered response categories ranging from "Not bothered at all" to "Bothered all of the time." Responses indicating less bother reflect better quality of life, while responses indicating greater bother reflect worse quality of life.
