Noninvasive assessment of skin barrier function: evaluating ceramide-based moisturizer using confocal Raman spectroscopy.
Article in Journal of biomedical optics, 2025. 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
Significance: Confocal Raman spectroscopy (CRS) is a noninvasive technique that enables detailed biochemical analysis of the skin, providing insights into its structural and molecular composition. Atopic dermatitis and hand eczema, both characterized by impaired skin barrier function, require effective monitoring tools to assess treatment efficacy. Aim: We aimed to quantitatively evaluate changes in skin physiological and biochemical parameters following the application of a ceramide-based moisturizer (test cream) compared with an aqueous moisturizer (control cream) in healthy volunteers and eczema patients. Approach: Skin physiological assessments and CRS measurements were performed to evaluate water content and ceramide levels in both superficial and deeper skin layers after application of the two moisturizers. Results: CRS revealed a significant increase in water content following test cream application, indicating improved skin hydration, whereas physiological measurements detected no statistically significant changes, underscoring the greater sensitivity of CRS. The test cream also significantly enhanced ceramide levels in both superficial and deeper skin layers, whereas the control cream increased ceramide levels only in the superficial stratum corneum (SC). Conclusions: These findings suggest that the test cream has a substantial positive impact on hand eczema, potentially improving both skin barrier function and biochemical properties.
