Background: Melasma is a common disorder of hyperpigmentation affecting millions of people worldwide. All the exact pathways to understand the complete pathogenesis of melasma is unknown. Aims: To determine the biophysical characteristics of melasma skin compared to the normal surrounding skin. Methods: Thirty-six patients with melasma were recruited in this case-control study. The subtype of m...

BACKGROUND Melasma is a common condition of Latino women that detracts from their quality of life (QOL). The prevalence and impact of melasma in Latino men is not well characterized. AIM To assess the prevalence of melasma and its association with QOL in Latino men from Mexico and Central America working in the USA. METHODS The prevalence of melasma was assessed in three studies of Latino m...

Melasma is a hyperpigmented dermatological condition common in females. Drugs such as steroids, cosmetics, and photosensitizing agents are known to cause melasma. We report here a case of an adult male with obsessive-compulsive disorder, receiving clomipramine, who developed melasma.

Melasma is a complex multifactorial disorder whose pathogenesis is not well understood. In addition to increased pigmentation, increased vascularity associated with pigmentation is present. A variety of topical treatments targeting pigmentation are available with temporary improvement of mainly the epidermal components of melasma. Intense pulsed light (IPL) is a broadband light source that can ...

BACKGROUND Melasma is a common hypermelanosis of the face. The use of a classical Q-switched ruby laser (QSRL) to treat melasma is discussed controversially and is associated with frequent adverse effects, such as hyper- or hypopigmentation. Recently a fractional-mode (FRx) QSRL was developed to minimize the adverse effects of classical QSRL. The objective of this research was to evaluate the e...

Epidermal melasma is a common hyperpigmentation disorder that can be challenging to treat. Although current treatment options for melasma are limited, topical skin-lightening preparations have widely been used as alternatives to hydroquinone. In this prospective, single-arm, open-label study, treatment of epidermal melasma with a novel cream formulation containing nicotinamide 4%, arbutin 3%, b...

Melasma is a chronic skin disorder that results in symmetrical, blotchy, brownish facial pigmentation. It is more common in women than in men, it generally starts between 20 and 40 years, and it can lead to considerable embarrassment and distress. The aims of this article is to evaluate the treatment with the microneedling method in 18 female and 4 male with recalcitrant melasma. All patients d...

Actinic lichen planus is a clinical variant of lichen planus, involving mainly sun-exposed areas and manifested as annular lesions with a pigmented center surrounded by a hypopigmented zone. A rare presentation of actinic lichen planus mimics melasma but have distinctive histopathologic picture in favour of actinic lichen planus. Herein, we report a 14-year-old boy who presented with a me...

Melasma is a cutaneous disorder associated with an overproduction of melanin by the tyrosinase enzyme. A proprietary oligopeptide (Lumixyl) was previously shown to competitively inhibit mushroom and human tyrosinase without the associated toxicity of hydroquinone. The aim of this split-face, randomized, double-blind and placebo-controlled pilot study was to determine the effect of twice-daily t...
