Facial Melanosis: A Comprehensive Review of Uncommon and Common Presentations with Personal Experience.
Review in Indian journal of dermatology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Facial melanoses (FMs) encompass a diverse group of disorders characterised by altered facial pigmentation, particularly prevalent in individuals with darker skin types, such as the Indian population. While common causes like melasma, post-inflammatory hyperpigmentation, and lichen planus pigmentosus are well documented in the literature, this review emphasises the lesser-known and uncommon causes of FM. These include facial acanthosis nigricans, maturational hyperpigmentation, frictional facial melanosis, and seborrheic melanosis, which are frequently observed in Indian populations but remain underrecognised and understudied. The aetiology of FM is multifactorial, involving genetic predisposition, racial factors, ultraviolet radiation, and exposure to photosensitising chemicals and allergens. Uncommon causes often present unique diagnostic challenges and are frequently misdiagnosed due to their overlapping clinical features. Diagnosis relies on clinical evaluation, supported by Wood's lamp examination, dermoscopy, and, in some cases, skin biopsy. FM can be classified into brown, blue, or mixed hypermelanosis based on the location and nature of melanin deposition. Management of these uncommon conditions is complex and requires a nuanced approach. Photoprotection remains a cornerstone of therapy, alongside topical depigmenting agents, chemical peels, and laser or light-based interventions. However, the risk of post-inflammatory hyperpigmentation in richly pigmented skin necessitates cautious and individualised treatment strategies. The lack of standardised guidelines for these uncommon causes further complicates management, underscoring the need for tailored therapeutic approaches. This review highlights the clinical significance of recognising and addressing uncommon causes of FM, which significantly impact patients' quality of life and psychosocial well-being. Enhanced awareness, further research, and the development of evidence-based treatment protocols are essential to improve outcomes for patients with these understudied conditions. By focussing on these uncommon causes, this review aims to fill a critical gap in the literature and provide a comprehensive resource for clinicians managing facial melanoses in skin of colour. Such comprehensive articles are lacking in literature.
