Filter by: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
OneDoc Picopulse™ is a radiopulse technology beauty grade device invented for treating melasma.
Background Melasma is a commonly acquired hypermelanosis that affects facial sun exposed areas, most commonly in Asians and other darker skin type females. Recent evidence has demonstrated melasma to be a photoaging disorder. The histological findings of melasma are similar to photoaging and include solar elastosis, increased mast cells and sebaceous glands, as well as increased vascularization. Pendulous active melanocytes with weakened basal membranes, and changes in nuclear morphology and chromatin texture of adjacent basal keratinocytes also seemed to be a characteristic feature of melasma. Objectives: To compare the difference of photoaging features of melasma skin and normal skin by optical coherence tomography (ApolloVue® S100 Image System, a 510(K) class II medical device) and reversal of photoaing features by 755nm picosecond alexandrite laser with diffractive lens. Methodology: We enroll 20 adults with facial melasma. The patients received 755nm picosecond alexandrite laser with diffractive lens array over whole face at W0, W4, and W8. Evaluation with VISIA, optical coherence tomography, Cutometer MPA580 at W4, W8, W12. All the patients will be instructed with use of moisturizer, gentle cleaning, and sunscreen use. Anticipated results and applications: This study expects to 1. understand the role of 755nm picosecond alexandrite laser with diffractive lens of reversal of photodamage and improving the melasma by evaluation with optical coherence tomography and other noninvasive methods. 2. Set evidence based guidance for melasma treatment and set the protocol or clinical path.
Melasma is a hyperpigmentation disorder that is probably exacerbated by visible light. Opsin receptors (OPN 1, 2, 3, 4 y 5) were described in the skin, being capable of activating melanogenesis induced by visible light. The aim of this study was to evaluate the expression of OPN in melasma skin and its changes following treatment with UV-Vis filter and 0.05% retinoic acid for 12 weeks.
The objective of the study was to compare the level of serum FT4 and TSH in patients with mild melasma and moderate-severe melasma. The determination of melasma lesion could also be known by using Janus II facial analysis UV light and polarization light to analyze the pattern of hyperpigmentation on melasma. This was a descriptive-analytic study used a cross-sectional method that was performed in 2019 at two different dermatology and venerology clinics in Indonesia, Cipto Mangunkusumo Hospital Jakarta and Gatot Subroto Army Hospital Jakarta. Forty-eight subjects with melasma, 50% diagnosed with mild melasma and 50% with moderate-severe melasma according to the modified melasma area and severity index (mMASI) score. The level of serum FT4 and TSH were then measured in both groups of the patients.
Study's objectives are to determine proportion of melasma cases in hyperthyroid patients and to compare severity of melasma before and after medications of three months hyperthyroid therapy using modified melasma area and severity index (mMASI) score. A quasi experimental (pre-post intervention) study was conducted in Jakarta in August 2019-February 2020.
It is a randomized controlled trial in which investigators determine the efficacy of tranexamic acid (TA) by mesotherapy in comparison to normal saline on participants having Melasma.
The primary objective is to evaluate the efficacy, of D.O.S.E formulations in the treatment of melasma and cutaneous signs of aging.
A randomized clinical trial will be done on 92 patients , randomly divided into two groups by lottery method to compare the efficacy and safety of topical silymarin cream 0.7% with topical 4% hydroquinone cream. Patients will be treated for 3 months and for the next 3 months will be followed up for relapse of melasma.
