Active clinical trials for "Melanosis"

To develop and evaluate a pharmaceutical formula based on green banana peel extract for the treatment of melasma.

This is a single centre, 2-cell, single blinded full-face (products applied at lesional sites) study to evaluate changes in melasma through a cosmetic facial serum formulation and marketed 2% Hydroquinone product

To assess the ability of a new 4% Hydroquinone formulation (Melanoderm 4% Crema) to reduce melasma on the face, using a split-face randomization design, evaluating the MASI Score from baseline to week 4 and week 8, in both half-faces receiving active treatment vs. placebo. To assess the tolerance of a new 4% Hydroquinone formulation (Melanoderm 4% Crema) on the face. To assess patients' satisfaction regarding Melanoderm 4% Crema after 8 weeks.

This proof of concept study will be conducted to assess the aesthetic improvement in refractory mixed type melasma in subjects treated with two FDA 510K approved devices: Q Switched Nd: YAG Laser vs. Alex TriVantage

Main objective is to show that a photoprotective sunscreen having a protection against the visible light is more effective than a sunscreen having the same UVA AND UVB protection but with a low (weak) protection against the visible, to prevent the relapses of the melasma during the summertime.

Tri-split face study of skin resurfacing modalities for the treatment of melasma, comparing the medium depth trichloroacetic acid peel, CO2 laser and Qs-NdYag laser.

The aim of this pilot study is to conduct a controlled comparison of the efficacy and safety of a combination peel (glycolic acid and salicylic acid) as compared to glycolic acid peel alone in the treatment of melasma. Our primary outcome is objective improvement in pigmentation as evaluated using a colorimeter. Our secondary outcomes are subjective improvement using the Melasma Area and Severity Index (MASI) and Patient and Physician Global assessment, as well as assessment of treatment tolerability and patient satisfaction.

The purpose of this study is to prospectively gather data on the efficacy and tolerability of spironolactone to treat refractory melasma and to compare treatment response of randomized 50 mg, 100mg, and 200mg per day dosing.

BACKGROUND: Malar melasma has a chronic and recurrent character that may be related with epigenetic changes.

Melasma is a fairly common condition resulting in hyperpigmented macules on the face. Melasma is difficult to treat and has a significant negative impact on the patient's quality of life. Melasma is worsen when exposed to high energy visible light (blue and violet light) of the solar spectrum. Blue light emitted by LED screens from computers, tablets, televisions and even mobile phones is currently suspected (via media channels) to induce harmful effects on the skin, including pigmentation and photoaging. These screens, however, emit much lower irradiances than those of the solar spectrum, and the probability that these irradiances impact the skin is very low. The objective of the study is to assess the effect of blue light emitted by computer/television screens on the intensity of melasma pigmentation. To do this, it is proposed to use maximized conditions that could be encountered in normal daily life, namely a simulation of blue light exposure (420-490nm) at 20 cm from a laptop LED screen, 8 hours a day for 5 days. Since it is not proposed to expose a person for 8 hours a day, a solar simulator with appropriate filters will be used to emit a spectrum of between 420 and 490 nm with a compatible intensity for an acceptable duration of exposure (around 30 minutes a day). Twelve patients will be included in the study and exposed on a half-face from Day1 to Day5. The other half-face will serve as unexposed control. The effect of blue light on the melasma lesions will be assessed from Day 1 to Day 6 using chromametry and a modified MASI on standardized photographs. A final evaluation visit will be performed at Day 15.
