Active clinical trials for "Melanosis"

Evaluate atrophogenic potential of long-term use of Tri-Luma Cream on facial Melasma through biopsy examination.

The purpose of this investigation is to evaluate safety and efficacy of the Cutera enlighten dual-pulse duration, dual-wavelength 532nm KTP/1064nm Nd:YAG laser for the treatment of melasma and lentigines on the face in Asian skin.

The application of Platelet Rich Plasma (PRP) on three occasions with an interval of 15 days between each one, is related to a decrease in the intensity of the spots and improvement in the quality of the skin of patients with melasma.

A Comparative study for Efficacy and Safety Between 4% hydroquinone cream with or without Fractional Picosecond 1,064 nm Laser for the Treatment of Dermal or Mixed Type Melasma

Kligman's trio remains the gold standard treatment for melasma. It contain hydroquinone which is an effective anti-melanogenic compound but that has poor tolerance and numerous side-effects. Thiamidol has been proven to be at least as effective as hydroquinone and has a very good safety profile. The objective of this study is to compare the Kligman's trio to the same preparation in which hydroquinone is replaced by thiamidol.

This study will enroll 20 adult Hispanic women. Participants will apply 4% hydroquinone cream twice daily to affected areas on the face for 14 weeks and half the face will be peeled with 20-30% salicylic acid every two weeks for a total of 4 peels. The first two peels will be 20% salicylic acid and the second two peels will be with 30% salicylic acid. The purpose of the study will be to evaluate the safety and efficacy of salicylic acid combined with 4% hydroquinone versus 4% hydroquinone alone.

Melasma is an acquired discoloration of the skin characterized by brown patches. Chemical peels using agents such as Jessner's solution and trichloroacetic acid (TCA) are commonly used to treat melasma. A chemical peel involves applying the peeling agent to the skin for a short period. The skin will peel similar to a sunburn, and moisturizers are applied to the skin. Although both agents are well-accepted, there have been no good comparisons of the two agents. The purpose of this study is determine if there is a difference in the effectiveness of these two agents.

Methodology: Fifty female patients presented with melasma (symmetrically distributed hyperpigmented macules and patches on the face) diagnosed by consultant dermatologist on clinical presentation were included in this study. The sample size was calculated by WHO Sample Size calculator taking 31% proportion of excellent response with 4% hydroquinone as an adjuvant to oral tranexamic acid as compared to 2.25% proportion of excellent response with 20% azelaic acid, 80% power of test and 5% significance level. After randomization, patients were divided into two groups. Group A was managed with 4% hydroquinone cream as an adjuvant to oral tranexamic acid (250 mg twice daily) while group B was managed with topical 20% azelaic acid (daily at night) for six months. Clinical evaluation was done initially at the start of therapy and then at 2nd, 4th and 6th month using MASI score and patient's response. Efficacy was assessed in both groups at the end of therapy after six months.

Comparison of 30% Metformin and 2% Nicotinamide lotion with kligman formula in the treatment of Melasma

Melasma is an acquired discoloration of the skin characterized by brown colour changes commonly on the face. The duration of this double-blind clinical trial will be 12 weeks. The control group will receive treatment with topical Hydroquinone (4%) and a Broad spectrum UV sunscreen. The experimental group, 4% topical hydroquinone and a Broad spectrum UV-visible light sunscreen. Visible light has melanotic properties and avoiding it can be part of the treatment for melasma patients. The estimated number of subjects to be recruited and randomized for the study is at least 25 per group. The purpose of this study is determine if there is a difference in the improvement between these two sunscreens types. Melasma Area and Severity Index (MASI) score will be assessed at the beginning of the study and at weeks 4, 8, and 12. Photographs, colorimetry and histological assessment will be also evaluated. Occurrence of adverse effects will also be recorded.
