Melasma, a common cause for seeking dermatologic care, is a chronic condition of skin hyperpigmentation. With a poorly understood pathogenesis, and no universal cure, melasma is a challenge for many dermatologists. For decades, there has been investigation into the role of oxidative stress in
Background: Melasma is a common skin disorder. Nd:YAG laser toning is a popular treatment for melanin clearance. Treatment efficacy is limited by factors such as presence of reactive oxygen species, DNA damage, TEWL, and skin barrier
Melasma is a difficult-to-treat, recurrent pigmentary disease. Combined therapy gives better, longer-lasting results.To determine the clinical effects of a treatment protocol of trichloroacetic acid, phytic acid and ascorbic acid peel combined with oral Melasma is a chronic dermatologic condition with an incompletely understood pathogenesis and well-demonstrated impact on patient quality of life. Melasma is a common cause for seeking dermatologic care, and with no universally efficacious therapy or cure, com-bination treatment is the best approach
BACKGROUND
Melasma, also known as mask of pregnancy, is a common, acquired hypermelanosis seen in women with Fitzpatrick skin types II-V, and is often recalcitrant to treatment with depigmentation agents. Glycolic acid has been added to hydroquinone formulations in the past to enhance their
BACKGROUND
Photoaging of the hands is common due to frequent exposure to environmental factors.
OBJECTIVE
To evaluate the efficacy of a topically applied cream formulated with an alpha-hydroxy acid, depigmenting agents, and antioxidants to improve the appearance of characteristics associated with
Vitamin C (L-Ascorbic acid) has many favourable effects on the skin such as antioxidant, anti-aging and whitening effects. Its instability and low permeability limit its pharmaceutical use in cosmetic and dermatological products. Instead, Mg ascorbyl phosphate (MAP), an ascorbic acid derivative, has
Melasma is a pigmentary disorder of unclear etiology with numerous treatment options and high recurrence rates. Laser and light therapies may be utilized cautiously as second- or third-line options for recalcitrant melasma, but low-energy settings are preferred due to the risk of postinflammatory
An aqueous extraction of moringa (Moringa oleifera) leaves were prepared as the edible coats for keeping the quality of the giant freshwater prawn (Macrobrachium rosenbergii). In addition, the antioxidant properties and activity; total phenolic content (TPC), total flavonoid contents
Introduction: Melasma is a condition of hyperpigmentation of the facial skin that increases in prevalence with ageing. The alleged involvement of reactive oxygen species and antioxidants is the basis of the pathology of melasma.
Oxidative stress, determined by the balance between the production of damaging reactive oxygen species (ROS) and antioxidant defences, is hypothesized to play an important role in shaping the cost of reproduction and life history trade-offs. To test this hypothesis, we manipulated reproductive
Exposure to the sun, ultraviolet radiation, and oxidative stress are the chief etiologic factors responsible for melasma. The ingredients of Korean red ginseng powder, which include ginsenoside and phenolic compounds, have antioxidative effects and reduce ultraviolet B-induced pigmentation. This
L-Cysteamine is a biological antioxidant produced during the coenzyme A metabolism cycle and is naturally present in all mammalian cells. The efficacy of topical cysteamine for the treatment of melasma has been recently shown in two double-blind, randomized, and placebo-controlled clinical trials.
BACKGROUND
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 in vitro without the associated cytotoxicity of hydroquinone and to
BACKGROUND
Multiple modalities have been used in the treatment of melasma, such as bleaching agents, chemical peels, and antioxidants. Topical zinc sulfate has peeling and antioxidant effects.
OBJECTIVE
The objective was to evaluate the efficacy and safety of topical 10% zinc sulfate solution in the
