Study on the Functional Impact of Cosmetics on Improving Self-Esteem and Quality of Life in Black Women
The goal of this clinical trial is to evaluate whether the use of dermocosmetics containing Bioceramides and Niacinamide can improve post-inflammatory hyperpigmentation and promote positive impacts on self-esteem and quality of life in Brazilian Black women with facial hyperpigmentation (Fitzpatrick skin types IV to VI).
The main questions it aims to answer are:
- Does the treatment improve hyperpigmentation severity as measured by HASI and IGA scores?
- Does the treatment improve participants' self-esteem and quality of life as assessed by MELASQoL and DLQI questionnaires?
Participants will:
- Use a standardized skincare routine including cleanser (0.2% Bioceramides), moisturizer (2% Niacinamide + 1% Bioceramides), serum (5% Niacinamide + 3% Bioceramides), and SPF 30 sunscreen for 12 weeks.
- Attend study visits at baseline, week 6, and week 12.
- Undergo standardized facial photography and clinical assessments by specialists at baseline, week 6, and week 12.
- Complete questionnaires related to self-esteem and quality of life at baseline, week 6, and week 12.

Eksperimentel: Intervention
Participants will receive a standardized facial skincare regimen to be used daily for 12 weeks, including a cleanser (0.2% Bioceramides), moisturizer (2% Niacinamide + 1% Bioceramides), serum (5% Niacinamide + 3% Bioceramides), and SPF 30 sunscreen (non-investigational). Products will be used daily, with cleanser twice daily, moisturizer in the morning, serum at night, and sunscreen twice daily. Participants will undergo evaluations at baseline, week 6, and week 12, including standardized photography and assessment using Hyperpigmentation Area Severity Scale (HASI) and Investigator's Global Assessment (IGA). Quality of life will be assessed with Melasma Quality of Life Scale (MelasQoL) and Dermatology Life Quality Index (DLQI). Participants will complete daily diaries to record product use and any reactions during the study, and will assess perceived product efficacy at the final visit. |

Change in Hyperpigmentation Severity Assessed by Hyperpigmentation Area Severity Scale (HASI)
Tidsramme: Baseline, Week 6, and Week 12
|
The Hyperpigmentation Area Severity Scale (HASI), adapted from the Melasma Area Severity Index (MASI), will be used to evaluate pigmentation severity.
The face will be divided into four regions (forehead, right malar, left malar, and chin).
Hyperpigmentation severity will be assessed based on three components: pigmentation intensity and homogeneity (both scored from 0 to 4), and the affected area (scored from 0 to 6).
A weighted sum will be calculated for each region using the following formula: HASI = 0.3 × (area score) × (intensity + homogeneity) for the forehead and malar regions, and 0.1 × (area score) × (intensity + homogeneity) for the chin.
The total HASI score will be obtained by summing all regions, ranging from 0 to 48, with higher scores indicating greater hyperpigmentation severity.

Visual Assessment of Post-Inflammatory Hyperpigmentation Using Standardized Facial Photography
Tidsramme: Baseline, Week 6, and Week 12
|
Standardized facial photographs will be obtained at each study visit and will be evaluated by a dermatologist to assess post-inflammatory hyperpigmentation.
Images will be captured under visible light using a standardized protocol (Rossi et al., 2011), including three facial views (frontal, left 45°, and right 45°).
The face will be divided into seven regions for visual analysis and quantification of pigmented areas using ImageJ software (version 1.45p, NIH).
All photographs will be acquired using consistent camera settings, lighting conditions, and participant positioning throughout the study to ensure comparability.

Change in Hyperpigmentation Severity Assessed by Investigator's Global Assessment (IGA)
Tidsramme: Baseline, Week 6, and Week 12
|
The Investigator's Global Assessment (IGA) is a visual assessment that will be used to provide an overall evaluation of post-inflammatory hyperpigmentation severity.
Assessments will be performed by a dermatologist using a 6-point scale ranging from 0 to 5, according to morphological characteristics of pigmentation: 0 = no hyperpigmentation; 1 = almost clear; 2 = mild but noticeable hyperpigmentation; 3 = moderate hyperpigmentation (medium brown); 4 = severe hyperpigmentation (dark brown); and 5 = very severe hyperpigmentation (very dark brown to nearly black).
Higher scores will indicate greater severity of pigmentation.

Change in Quality of Life Assessed by Melasma Quality of Life Scale (MelasQoL)
Tidsramme: Baseline, Week 6, and Week 12
|
The Melasma Quality of Life Scale (MelasQoL) will be used to assess quality of life related to post-inflammatory hyperpigmentation.
The questionnaire consists of 10 items divided into three domains: emotional well-being, social life, and self-esteem/daily activities.
Each item is scored from 1 (not bothered at all) to 7 (constantly bothered), with higher scores indicating worse quality of life.
The MelasQoL is a validated instrument for assessing the impact of melasma and other pigmentary disorders on patients' quality of life.

Change in Quality of Life Assessed by Dermatology Life Quality Index (DLQI)
Tidsramme: Baseline, Week 6, and Week 12
|
The Dermatology Life Quality Index (DLQI) will be used to assess quality of life and self-esteem related to post-inflammatory hyperpigmentation.
The questionnaire consists of 10 items covering six domains: symptoms, emotions, daily activities, work/school, social functioning, and treatment.
Each item is scored from 0 (not at all/not relevant) to 3 (very much), with total scores ranging from 0 to 30.
Higher scores indicate greater impairment in quality of life.
