Active clinical trials for "Melanosis"

The purpose of this study is to evaluate the topical safety (tolerability/acceptability) and efficacy of two facial sunscreen in improving wrinkles, fine lines and melasma after 84 +/- 2 days of use under normal conditions on the face by adult participants. For these investigational products, safety parameters, clinical efficacy, instrumental efficacy (assessment of color intensity and size of melasma spots and assessment of wrinkles and fine lines), facial imaging, and self-perceived efficacy through subjective questionnaire and quality of life questionnaires (MELASQol) will be evaluated, as well as an open emotional statement written by the participant at the end of use experience".

The purpose of this study is to compare a hydroquinone skin care regimen alone to a combination of Revlite Laser treatment with a hydroquinone skin care regimen for the treatment of melasma.

Melasma is an acquired disorder of hyperpigmentation characterised by blotchy, light-to-dark brown macules distributed symmetrically on the sun-exposed parts of the body. Although many factors have been proposed to have a role in pathogenesis, the exact ethology is yet to be understood. The most commonly identifiable risk factors include ultraviolet radiation, genetic predisposition, pregnancy, oral contraceptives, thyroid disease and drugs like antiepileptic. The excessive pigmentation has been attributed to both melanocytosis (increased number of melanocytes) as well as melano genesis (excess production of melanin) as confirmed in a histopathological study on Asian patients.] Furthermore, a vascular component has also been proposed to play a role in the pathogenesis of melisma. Kim et al. have found that lesion melasma skin had greater expression of the vascular endothelial growth factor in keratinocytes compared to nearby nonlesional skin.

Melasma Is an acquired, chronic, recurrent, symmetrical hypermelanosis, which is characterized by brown patches of variable darkness on sun exposed areas of the body. It is more common in women. It is common psychologically and emotionally distressing cosmetic problem in affected patients .

Melasma is an acquired pigmentary disorder, occurring most commonly on the face. It is more prevalent in females and darker skin types. Melasma is mainly a clinical diagnosis consisting of symmetric reticulated hypermelanosis in three predominant facial patterns: centrofacial, malar, and mandibular. Melasma, though benign, can be extremely psychologically distressing and has been shown to have a significant impact on quality of life, social and emotional wellbeing. Multiple factors are implicated in the pathogenesis of melasma; however, the definite underlying mechanisms are not yet completely established. Ultraviolet exposure is one of the leading etiological factors, besides genetic and hormonal factors.

Melasma is a common acquired disorder characterized by symmetric, hyperpigmented patches with an irregular outline, occurring most commonly on the face. The therapy for melasma has always been challenging and discouraging. Platelet rich plasma has been used over the last several years as an effective treatment in various surgical and medical fields. In recent years, Platelet rich plasma has also started to be used in the field of cosmetology. This study is designed to evaluate the therapeutic effect of platelet rich plasma in melasma.

The objective of this study is to assess and compare the efficacy of tranexamic acid intradermal microinjection alone versus its combination with low power fractional CO2 laser in a sequential pattern. In all participants one half of the face will be randomly assigned to low power fractional CO2 laser while other side to Tranexamic acid intradermal microinjections on the 1st session. This split face session will be repeated every six weeks for 3 sessions. In addition, Tranexamic acid intradermal microinjections will be applied for full face at the 2nd and 4th week of each split face session. The response will be evaluated by the Melanin and erythema Indices which will be measured using reflectance spectrophotometer, Dermoscopy and photography before starting the study, two and four weeks after the last session. The sessions will take 4 months for each patient and another one month free of sessions for follow up.

This study aims to assess the efficacy and safety of using combination of 755-nm picosecond alexandrite laser and 2% hydroquinone compared with 2% hydroquinone alone for the treatment of melasma: A randomized split-face controlled trial

Melasma is a common, acquired, esthetically disfiguring hypermelanosis of the face. Melasma is considered a disappointing challenge when treatment options are addressed. Diverse treatment modalities such as retinoic acid, hypo-pigmenting agents like hydroquinone, azelaic acid, and kojic acid, chemical peels, microdermabrasion, and lasers have been tried for the treatment of melasma. There is no universally proven therapy that induces and maintains remission of the condition. Q-switched: Nd YAG laser toning and platelet rich plasma (PRP) are promising treatments for melasma.The aim of this work is evaluate the efficacy and safety of combined PRP and Q-switched: NdYAG laser in the treatment of melasma using clinical assessment, in addition to assessment of Melanin Index and Erythema Index.

To compare the efficacy and safety of cryopeeling (using Liquid Nitrogen) and tranexemic acid (cyclokapron) versus chemical peeling (using TCA 20%) in treatment of melasma.
