A 4-week Study Investigating Two Targeted Brightening Serum (A and B) Versus 4% Hydroquinone in Women With Mild to Severe Full-face Hyperpigmentation

8. června 2026 aktualizováno: Revision Skincare

A Multi-Center, Randomized, Blinded, Split-Face, Controlled Clinical Study to Assess Two Targeted Brightening Serum (A and B) Paired With 4% Hydroquinone

This a short four-week pilot study to measure the efficacy and tolerance of two brightening serums (cosmetics) versus 4% hydroquinone. The study was conducted in two sites across the USA, one in PA and in one in CA. The goal was to run the pilot study in the summer to understand the role of these two potential brightening serums in helping the appearance of skin tone evenness.

Přehled studie

Detailní popis

This is a four-week multi-center, single-blind, randomized, split-face, controlled pilot study conducted to assess the efficacy and tolerance of two pigment correction formulations (Brightening Serum A and Brightening Serum B) compared to 4% Hydroquinone split face when used over the course of 4 weeks by healthy females with clinically determined mild to severe facial hyperpigmentation, including melasma on the global face. Subjects will be randomized into 2 cells which will receive the following split face treatments:

  • Cell 1: Brightening Serum A versus 4% Hydroquinone
  • Cell 2: Brightening Serum B versus 4% Hydroquinone It was hypothesized that the Brightening Serum A and B will produce statistically significant improvements at post-baseline timepoints when compared with baseline, and comparable improvements versus the standard of care 4% Hydroquinone across the primary endpoint, secondary and tertiary endpoints. Additionally, the Sponsor's test materials will be well tolerated by subjects, with no statistically significant increases in scores for tolerability/safety parameters, specifically erythema and dryness, at any study timepoint when compared with baseline scores. Furthermore, the Sponsor's test materials will be well perceived by subjects according to analyses of self-assessment questionnaires, with a statistically significant proportion of favorable responses compared to unfavorable responses and/or a statistically significant improvement in subject response values when compared with baseline.

Measurement of facial Melasma
Časové okno: Baseline, week 2 and week 4
The MASI score is a clinical tool used to assess the severity of melasma, a hyperpigmentation disorder, in terms of both area and darkness. It quantifies the extent and intensity of melasma in four facial regions: the forehead (F), right malar region (MR), left malar region (ML), and chin (C), corresponding to 30%, 30%, 30%, and 10% of the total face, respectively. A decrease in score indicates improvement
Baseline, week 2 and week 4
Incidence of Treatment- Emergent Adverse Events
Časové okno: Baseline, week 2, and week 4
Local cutaneous tolerability was evaluated by assessing the signs and symptoms of the following objective and subjective irritation parameters globally on each subject's face. Objective irritation (clinically graded): erythema, edema, and dryness. Subjective irritation (assessed by subjects): burning, stinging, and itching. Local cutaneous tolerability was evaluated by assessing objective (erythema, edema, and dryness) and subjective (burning, stinging, and itching) irritation parameters globally on each subject's face using a 4-point scale (0 = none to 3 = severe). A decrease in value indicates an improvement.
Baseline, week 2, and week 4
