RESUMO
BACKGROUND: Facial hyperpigmentation occurs in multiple conditions. In addition, many Asian women desire a lighter skin color. Thus, there is a need for the development of skin lightening agents, and niacinamide and tranexamic acid (TXA) are promising candidates. OBJECTIVE: To assess the effectiveness of a combination of niacinamide and TXA as a topical moisturizing formulation for treatment of irregular facial pigmentation. MATERIALS AND METHODS: A total of 42 Korean women (age range: 30-60 years) who were not pregnant, nursing, or undergoing any concurrent therapy were enrolled in this study for 8 weeks. Subjects used a twice-daily regimen of either a moisturizing cream containing 2% niacinamide + 2% TXA (test formulation; n = 21) or cream vehicles (vehicle control; n = 21) in addition to an assigned sunscreen each morning. Pigmentation was measured objectively using a mexameter and chromameter, in addition to physicians' assessment using clinical photographs. RESULTS: The niacinamide + TXA formulation regimen was significantly (P < 0.05) more effective than the vehicle control formulation regimen in reducing the appearance of pigmentation. CONCLUSION: A formulation containing the combination of niacinamide + TXA reduced the appearance of irregular pigmentation, providing an effect beyond that achieved with sunscreen.

This report describes a case of facial hyperpigmentation in a patient with Crohn's disease receiving adalimumab, a tumor necrosis factor (TNF)-alpha inhibitor. The onset of hyperpigmentation coincided with adalimumab administration, and its discontinuation resulted in significant improvement. Histopathological findings suggest a postinflammatory process at the dermo-epidermal junction. However, the precise mechanism remains unclear.

Disorders of hyperpigmentation are common and challenging conditions which can arise due to a myriad of etiologic factors. Many of them can present across skin types but are more common in skin of color individuals with Fitzpatrick skin types III-VI. Facial hyperpigmentation, in particular, can have a significant impact on the quality of life of affected individuals due to its increased visibility. This article provides a comprehensive review of disorders of facial hyperpigmentation including epidemiology, pathogenesis, diagnostic considerations, and treatment approaches for these conditions.

Hyperpigmentation disorders, such as post-inflammatory hyperpigmentation and melasma, are common conditions affecting all skin types. These conditions are largely benign and are influenced by numerous endogenous and exogenous factors impacting melanocyte activity and melanin production. Current treatment modalities for these conditions fall into broad categories, including photoprotection, topical and systemic therapies, chemical peels, and laser or light-based therapies. Biological differences in skin of colour require additional consideration when deciding on treatment and management. This narrative review provides an inclusive summary of these conditions and compares the current treatment options with a specific focus on skin of colour. Photoprotection and sunscreens protective against both UV and visible light are recommended for all individuals. Topical therapy is the recommended first-line treatment, with the gold standard being hydroquinone, which can be used alone or in combination with other agents. Chemical peels and laser or light-based therapies are also effective adjunctive methods of treatment; however, caution should be taken when used in patients with richly pigmented skin due to the increased risk of post-inflammatory hyperpigmentation.
RESUMO
Chikungunya although rare should be considered in any neonate presenting with fever and facial hyperpigmentation or encephalopathy especially in endemic areas.
RESUMO
INTRODUCTION: Latanoprost is a prostaglandin F2α analogue, which has been used as a first-line drug for open-angle glaucoma. Common side effects of latanoprost include hyperpigmentation. While it usually occurs on irides or periocular skin, diffuse facial hyperpigmentation is rarely reported. CASE PRESENTATION: A 71-year-old woman was presented with diffuse gray-brown colored maculopatches on her face. The symptom appeared 1 week after she started to use latanoprost eye drops for glaucoma. Biopsy specimen revealed vacuolar degeneration of dermo-epidermal junction and pigment incontinence in dermis. OBJECTIVE: The aim of this paper is to introduce a rare adverse effect of latanoprost and effective way of treatment. METHODS: We stopped her from using latanoprost. She was also treated with 532-nm potassium titanyl phosphate laser and low-fluence 1064-nm Q-switched Nd:YAG laser, while using topical agents. RESULT: After 10 weeks, we observed hyperpigmentation of her face was effectively and safely treated. The patient was satisfied with the result. CONCLUSION: Diffuse facial pigmentation could be one of the latanoprost-induced adverse effects and the laser treatments with topical agents we used can make it improve faster.

BACKGROUND: Acne and facial post-inflammatory hyperpigmentation are relatively common clinical conditions among adolescents and young adults, and inflict psychosocial injuries on sufferers. OBJECTIVE: To document the psychosocial and self-esteem implications of acne and facial hyperpigmentation on newly admitted undergraduates. MATERIALS AND METHODS: A cross-sectional survey was conducted among 200 undergraduates. Demographics and clinical characteristics were obtained and acne was graded using the US Food and Drug Administration 5-category global system of acne classification. Participants completed the Cardiff Acne Disability Index (CADI) and the Rosenberg self-esteem scale (RSES), and data were analyzed using SPSS 20. RESULTS: Mean age of acne onset was 16.24 ± 3.32 years. There were 168 (84.0%) cases categorized as almost clear, 24 (12.0%) as mild acne, 4 (2.0%) as moderate acne and 4 (2.0%) as severe acne. Acne with facial hyperpigmentation, compared to acne without hyperpigmentation, was associated with significant level of anxiety in 30 participants (26.5% vs 10.3%, p=0.004) and emotional distress in 40 (35.4% vs 10.3%, p<0.001). Acne severity correlated with total CADI score but not with total RSES score. Quality of life (QoL) was significantly reduced among acne patients with facial hyperpigmentation (1.77±1.62, vs 1.07±1.02, p<0.001) compared to those without hyperpigmentation. Acne and facial hyperpigmentation was associated with social life interference, avoidance of public facilities, poor body image and self-esteem and perception of worse disease. There was no association between gender and QoL but acne was related to a reduction of self-worth. Low self-esteem was present in 1.5%, and severe acne was associated with an occasional feeling of uselessness in the male gender. CONCLUSION: Acne with facial hyperpigmentation induces poorer QoL and self-esteem is impaired only in severe acne. Beyond the medical treatment of acne, dermatologists should routinely assess the QoL and give attention to treatment of facial post-inflammatory hyperpigmentation among people of color.
RESUMO
We report a case of vertically transmitted chikungunya infection in heterozygous twin neonates presenting as seizures, encephalopathy, midfacial hyperpigmentation, anemia, and thrombocytopenia. This could be considered as a rare cause of neonatal seizure and identification would help in appropriate management.
