Filter by: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
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.
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.
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).
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".
Pigmentary disorders such as melasma, lichen planus pigmentosus and vitiligo can significantly affect patients' quality of life. Treatment responses are usually slow and typically have limited efficacy. In recent years, low level laser therapy has been an emerging treatment modality for androgenetic alopecia, acne, wound healing and photorejuvenation. This is a prospective, double-blind, split-body, randomized controlled trial assessing the efficacy of low level laser therapy with red light for pigmentary disorders such as, melasma, lichen planus pigmentosus and vitiligo.
Tranexamic acid and 1927 diode laser non-ablative fractionated laser for the treatment of Melasma.
Melasma is a chronic and relapsing acquired dyschromia due to an increased epidermal-melanin unit activity that affects sun-exposed areas mainly in women throughout the reproductive years. It is more common in women, accounting for 90% of all cases.The majority of patients are in third and fourth decades of their life. There are several risk factors that influence its appearance including genetic predisposition,exposure to heat and UV radiation, pregnancy, and exogenous hormones (such as oral contraceptives,thyroid hormones, and hormone replacement therapy). Other factors implicated are phototoxic drugs, anticonvulsant medications,and the use of certain cosmetics. Types of melasma are epidermal, dermal and mixed according to location of melanin.
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.
