BACKGROUND: Glaucoma is a leading cause of irreversible blindness worldwide and the second most common cause of blindness after cataracts. The primary treatment for glaucoma aims to lower intraocular pressure (IOP) with the use of topical medicines. Topical medication instillation techniques, such as eyelid closure and nasolacrimal occlusion when instilling drops, have been proposed as potential methods to increase ocular absorption and decrease systemic absorption of the drops. OBJECTIVES: To investigate the effectiveness of topical medication instillation techniques compared with usual care or another method of instillation of topical medication in the management of glaucoma or ocular hypertension...

Bioactive compounds from natural sources, due to their widely-recognized benefits, have been exploited as cosmeceutical ingredients. Among them, phenolic acids emerge with a very interesting potential. In this context, this review analyzes hydroxycinnamic acids and their derivatives as multifunctional ingredients for topical application, as well as the limitations associated with their use in cosmetic formulations. Hydroxycinnamic acids and their derivatives display antioxidant, anti-collagenase, anti-inflammatory, antimicrobial and anti-tyrosinase activities, as well as ultraviolet (UV) protective effects, suggesting that they can be exploited as anti-aging and anti-inflammatory agents, preservatives and hyperpigmentation-correcting ingredients...

The growing interest in skin lightening has recently renewed attention on the esthetic applications of Chinese herbal medicine. Although Scutellaria baicalensis Georgi is used for antipyretic and antiinflammatory purposes, its whitening effect remains unclear. This study reports three major findings: (1) S. baicalensis has a potent inhibitory effect on melanogenesis; (2) wogonin and its glycoside are the active components of S. baicalensis; and (3) O-methylated flavones from S. baicalensis, such as wogonin, inhibit intracellular melanosome transport...

The increasing melanin hyperpigmentation of dark skinned individuals was related to the high activity of melanocytes. Also smoking reactive the melanocytes to produce melanin. Gingival depigmentation is a periodontal plastic procedure which has been carried out by various techniques. A healthy 36-years-old female patient complained about unaesthetic gingiva and she had smoked over 17 years. Hyperpigmentation of gingiva observed on the labial surface of both maxilla and mandibula. Er,Cr:YSGG laser was used for depigmentation with wavelength of 2780nm, frequency of 20hz, and pulse energy between 0-300 Mj...

Recent studies have shown that plumbagin has anti-inflammatory, anti-allergic, antibacterial, and anti-cancer activities; however, it has not yet been shown whether plumbagin suppresses alpha-melanocyte stimulating hormone (α-MSH)-induced melanin synthesis to prevent hyperpigmentation. In this study, we demonstrated that plumbagin significantly suppresses α-MSH-stimulated melanin synthesis in B16F10 mouse melanoma cells. To understand the inhibitory mechanism of plumbagin on melanin synthesis, we performed cellular or cell-free tyrosinase activity assays and analyzed melanogenesis-related gene expression...

BACKGROUND: Cutaneous hyperchromias are disorders of skin pigmentation involving an increase of melanin production and its irregular accumulation in skin cells. It is known that the use of sunscreens helps to prevent changes in the skin pigmentation pattern, but the structural and morphological alterations that occur in the different types of hyperpigmentations need better elucidation. OBJECTIVE: To assess the influence of solar exposure and protection habits on the pattern of skin pigmentation using reflectance confocal microscopy (RCM)...

Tattoo, a Polynesian word meaning 'to mark', is a form of body modification done by inserting indelible ink into the dermis to change its pigmentation. Tattoos are done for social, cultural, and religious purposes. It has been in existence since the 18th century and was associated with sailors, lower class individuals, and criminals. However, since the late 20th century, tattooing has undergone a redefinition and shifted to an acceptable form of expression all over the world, including Nigeria, cutting across almost all age groups and socioeconomic class...

BACKGROUND: Melasma presents a significant challenge to laser surgeons. Aggressive treatments often result in rebound melasma or post-inflammatory pigmentary alteration. Recent reports suggest melasma pathogenesis may have a vascular component. Spectrocolorimetry can detect subtle or sub-clinical telangiectatic erythema within melasma lesions. For certain patients identified by spectrocolorimetry, effective melasma treatment may include vascular-targeted therapy together with pigment-specific treatment modalities...

Melasma is a human melanogenesis dysfunction that results in localized, chronic acquired hyperpigmentation of the skin. It has a significant impact on appearance, causing psychosocial and emotional distress, and reducing the quality of life of the affected patients. Tranexamic acid (TA) is a plasmin inhibitor used to prevent abnormal fibrinolysis to reduce blood loss and exerts its effect by reversibly blocking lysine binding sites on plasminogen molecules, thus inhibiting plasminogen activator (PA) from converting plasminogen to plasmin...

: Purpose: Hyperpigmentation occurs when melanin is overproduced in certain spots on the skin and is one of the most challenging skin conditions to treat. Although it is usually harmless, for cosmetic reasons, it is dreadfully bothersome to those who undergo it. It was reported that N-acetyl-glucosamine (NAGA) prevents melanin synthesis and alters the expression of numerous genes related to pigmentation. In spite of these advantages, NAGA cannot be employed in topical formulations due to its extremely polar characteristics...

Dyspigmentation along the Blaschko lines is strongly suggestive of a mosaic skin disorder. We report a 9-year-old male patient who presented with swirls and streaks of both hypo and hyperpigmentation involving the entire body. Additionally, he had hypertrichosis, musculoskeletal and minor neurodevelopment abnormalities but no intellectual disability. Cultured fibroblast displayed trisomy 7 mosaicism, which can explain this pigmentary phenotype. Widespread dyspigmentation associated with involvement of other organs should prompt systemic examination to detect additional anomalies and genetic evaluation should be considered, even with normal fetal karyotype...

Importance: Despite their great potential, medium and deep trichloroacetic acid peels are underused in light-skinned patients and are rarely used in darker-skinned patients because of the widespread fear of pigmentary complications and scarring. This concern has led many physicians to opt for the use of lighter types of peels (glycolic acid peel, Jessner peel, etc) and different lasers and intense light technologies. Trichloroacetic acid peels have been described in numerous publications...

Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

Cutaneous hyperpigmentation is a recognized adverse effect of chronic minocycline use occurring in up to 50% of patients. In this report we present a rare case of extensive skin hyperpigmentation involving both lower extremities in a patient receiving long term minocycline. The patient was receiving minocycline as suppression for chronic prosthetic joint infection. Risk factors associated with minocycline-induced cutaneous pigmentation (MICH) will be reviewed.

BACKGROUND: Fractional lasers were introduced to provide increased safety, while maintaining high efficacy and patient satisfaction. Patients with virtually all Fitzpatrick skin types could be safely treated using a wide spectrum of wavelengths and a broad array of skin conditions, and aging could be addressed. Although safety studies have been reported for ablative CO2 and erbium lasers, surprisingly few data are available on adverse events and complications associated with fractional lasers...
