Filter by:OneDoc Picopulse™ is a radiopulse technology beauty grade device invented for treating melasma.
1. To detect the efficacy and safety of combined TCA and MDA in treating melasma. 2. To compare the efficacy and safety of using different TCA concentrations (15% & 20%) alone and in combination with MDA in treatment of melasma.
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.
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 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 .
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
This study will involve collecting information about the regular medical care you receive for large cutaneous melanocytic nevi (LCMN) or neurocutaneous melanocytosis (NCM).
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.
This is a multicenter, ambispective, low-interventional clinical study evaluating molecular genetic markers for non-invasive differential diagnosis of benign and malignant pigmented skin and mucosal neoplasms. In retrospective cohorts genetics markers will be identified. In prospective cohort non-invasive adhesive system will be tested to identify malignant or benign lesions with prespecified sensitivity and specificity compared to other non-invasive techniques (i.e. dermoscopy) and using histopathological examination as a "golden standard".
