Filter by:The treatment of melasma and the maintenance of depigmentation represent a challenge due to its frequent recurrences. Pathophysiological mechanisms and factors have been linked to melasma such as inflammation, sun exposure, increased CD4+ T lymphocytic infiltrate and IL-17 in damaged skin. Tissue-resident memory T cells (Trm), derived from naïve T lymphocytes, are associated with the recurrence of lesions at the same sites but they have not been described in melasma. This a Cross-sectional, prospective analytical study. 20 female patients, 18 to 55 years of age, with diagnosis of melasma and mMASI score of at least 7, at least 1-year duration, lesional and perilesional skin biopsies were taken for PCR and DIF. The objective is to determine the transcription factors of Trm cells in malar melasma.
The primary objective of our study is to determine the efficacy of combined topical cysteamine cream with a 1927 diode non-ablative laser (Clear + Brilliant Permea®; Solta Medical, Inc.), compared to topical cysteamine (Cyspera) alone in the treatment of melasma. The main questions it aims to answer are - If melasma treatment with topical cysteamine cream is more effective when used with the Clear & Brilliant® Permea laser - The safety & efficacy of melasma treatment in various skin types using the Clear & Brilliantt® Permea laser in combination with topical cysteamine. Participants will - Come into our office for an initial screening appointment to determine if participant is eligible for the study - Come in for 3 laser treatments, 4 weeks apart, on 1 side of the face - Use the study provided Cyspera topical cream every day on the entire face for the 12 weeks on the study. Researchers will compare the side of the participants face not treated with laser to the side of the face treated with laser. The participants will be using Cyspera on both sides of their face.
Melasma is an acquired disorder of melanogenesis leading to hyperpigmentation and manifested by symmetrical brown to gray-black macules and patches with serrated irregular edges . It occurs especially in sun-exposed areas and affects young to middle-aged women. It is most commonly seen on the face and less commonly on the neck, arms, and chest . Platelet rich plasma (PRP) is defined as a small volume of autologous plasma that contains a high concentration of platelets obtained by centrifugation of autologous blood and subsequent suspension of platelets
Melasma is an acquired skin disorder characterized by hyper-melanosis. Melasma is a term that originates from the Greek root "melas" (black color) and was formerly known as chloasma. Melasma is more common in sun-exposed tissues such as the cheeks, chin, upper lip, and forehead. Melasma is a common dermatological disorder with a frequency of 8.8 percent in the United States, but it can be as high as 40 percent amongst females. Melasma affects mostly ladies and is most common throughout their reproductive years . Melasma causes an increase in melanin pigment synthesis owing to a surge in the number of melanosomes, which are membrane-bound cell organelles inside melanocytes where melanin biosynthesis occurs and is transported to keratinocytes. Except in rare situations, the number of melanocytes will not be enhanced. Melanocytes will grow in size, and dendrites will become more visible. Despite the fact that the specific causation is unknown, some elements are thought to have a role in the pathophysiological mechanisms of melasma). Among these, sun exposure (UV light) is the most powerful primary trigger for its growth, which explains melisma's propensity for certain areas of the body. Other major determinants include genetic predisposition, and female hormones - both endogenous (that is, during pregnancy) and exogenous (that is, during pregnancy) (contraceptives and hormone replacement therapy). Thyroid problems, medications, and cosmetics can all be aggravating factors. Evaluation and prevention of triggering variables are essential in order to avoid recurrence . The peeling effect of glycolic acid is due to chemo exfoliation capabilities, that rely upon aiding the elimination of keratinocytes, resulting in melanin reduction and speeding up the regeneration of skin. TA suppresses UV-stimulated plasmin action in keratin cells by blocking plasminogen appending to the keratin cells, resulting from lower free arachidonic acid levels or to reduced capacity of prostaglandins production, which reduces melanocyte tyrosinase activity . The study's implications are to analyze the efficacy of these two drugs in order to assess the better outcome of patients with evidence-based management.
Photobiomodulation (PBM) has been suggested as an alternative treatment for Melasma, showed by the in vitro data, inhibition of the tyrosinase enzyme and reduction in the pigment content by autophagy. This treatment compares with tranexamic acid, where it acts on similar pathways of melanogenesis. A total of 54 female participants, phototype scale Fitzpatrick ll - lV will be recruited which will be distributed among two groups: Light + placebo Home Care cosmetic product and Light sham + Home Care cosmetic product with tranexamic acid. The treatments will consist of 90 days, with application of photobiomodulation (PBM) once a week and application of the cosmetic product twice a day.
A double-blind, randomized, split-face controlled trial of 34 female patients with melasma was conducted. All subject were randomized to receive either intradermal tranexamic acid or placebo injection on the right or the left side of their face.
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.
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.
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
