Melasma is a dysregulation of the homeostatic mechanisms that control skin pigmentation and excess pigment is produced. Traditional treatment approaches with topical medications and chemical peels are commonly used but due to the refractory and recurrent nature of melasma, patients often seek alternative treatment strategies such as laser and light therapy. Several types of laser and light therapy have been studied in the treatment of melasma. Intense pulsed light, low fluence Q-switched lasers, and non-ablative fractionated lasers are the most common lasers and light treatments that are currently performed...

Skin of color comprises a diverse and expanding population of individuals. In particular, women of color represent an increasing subset of patients who frequently seek dermatologic care. Acne, melasma, and alopecia are among the most common skin disorders seen in this patient population. Understanding the differences in the basic science of skin and hair is imperative in addressing their unique needs. Despite the paucity of conclusive data on racial and ethnic differences in skin of color, certain biologic differences do exist, which affect the disease presentations of several cutaneous disorders in pigmented skin...

To evaluate the efficacy of a functional microarray of microneedles (MNs) plus topical tranexamic acid (TA) for melasma in middle-aged women in China.Thirty female subjects with melasma were enrolled in this study. The left or right side of the face was chosen randomly to be pretreated with a functional microarray of MNs, followed by topical 0.5% TA solution once per week for 12 weeks. The other half-face was the control, treated with a sham device plus topical 0.5% TA solution. At baseline and at weeks 4, 8, and 12 of treatment, clinical (photographic) evaluations and parameters determined by Visia were recorded...

Several studies observed that adiponectin, an important adipokine that improves glucose metabolism by regulating AMP-activated protein kinase (AMPK) signaling, is dermatologically beneficial. In our recent microarray data, we found that adiponectin expression was lower in lesional skin than in non-lesional skin of melasma patients. Given that AMPK is a key adiponectin signaling mediator, we investigated the role of adiponectin and AICAR, a cell-permeable AMPK activator, in melanogenesis. We herein showed that adiponectin and AICAR downregulated MITF, tyrosinase, TRP-1, and DCT expression and reduced melanin content in normal human and mouse melanocytes...

Pigmentation reflects skin darkening caused by melanin production, but excessive melanin synthesis may cause problems, such as melasma, solar lentigo, dark spots, and freckles. Considerable effort has been devoted to alleviating these undesired symptoms through the development of safe and effective depigmenting agents. Coumestrol, a plant-derived natural isoflavone with an estrogen-like structure and actions, is known to have anti-aging ability, but its potential depigmenting efficacy has not been evaluated...

Tranexamic acid is a novel treatment option for melasma; however, there is no consensus on its use. This systematic review searched major databases for relevant publications to March 2016. Eleven studies with 667 participants were included. Pooled data from tranexamic acid-only observational studies with pre- and post-treatment Melasma Area and Severity Index (MASI) showed a decrease of 1.60 in MASI (95% confidence interval (CI), 1.20-2.00; p < 0.001) after treat-ment with tranexamic acid. The addition of tranexamic acid to routine treatment modalities resulted in a further decrease in MASI of 0...

A 47-year-old woman presented with hyperpigmented patches on her upper extremities. The patient had begun using a topical estrogen cream in the affected areas prior to noticing the hyperpigmentation. A diagnosis of melasma secondary to topical estrogen cream was made. While systemic hormones are a well-documented trigger for the development of melasma, this case represents the first report of melasma associated with topical estrogens. Topical estrogens are frequently prescribed to postmenopausal women for skin rejuvenation...

Melasma is an acquired disorder of pigmentation that presents with asymptomatic symmetric darkening of the face. The pathogenesis of this condition is multifactorial and influenced by several factors including female sex hormones, genetic predisposition and ultraviolet light exposure. The management of melasma is usually directed at more than one of the causative etiologic factors and often incorporates a combination of topical agents, with or without the addition of physical modalities. Estrogen and angiogenesis are significant factors in the etiology of melasma...

Melasma is a common acquired pigmentary disorder marked by irregular hyperpigmented macules or patches and most commonly occurs in women of darker skin color. It is a chronic often-relapsing condition that causes negative psychosocial effects in those affected. Current treatments such as hydroquinone, kojic acid, and retinoids, among others, demonstrate variable efficacy and side-effect profiles. We conducted a comprehensive literature review examining the use of tranexamic acid (TA), a well-known anti-fibrinolytic agent, in the treatment of melasma...

Currently available treatment options for melasma include prevention of UV radiation, topical lightening agents, chemical peels, and light-based and laser therapies. However, none have shown effective and sustained results, with incomplete clearance and frequent recurrences. There has been increasing interest recently in oral medications and dietary supplements in improving melasma. We sought to evaluate the efficacy and safety/tolerability of oral medications and dietary supplements for the treatment of melasma...
