Changes in emotional response towards different facial application gestures following skincare application: An electroencephalogram approach.
Article in International journal of cosmetic science, 2026. 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
backgroundAmidst increasing global levels of stress and a growing concern for well-being, facial massage gestures have emerged as an option to improve the comfort and well-being of women.
objectiveTo characterize four emotional indices (stress, comfort, valence, and arousal) and their evolution when induced from two experimental and standardized facial gestures (Q and S).
methodsThis prospective, monocentric, intra-subject comparison study was conducted in Japan where 17 healthy female subjects aged 38-55 years were enrolled. Two experimental standardized gestures (Q and S) were administered in pairs to the subjects over 2 days. Gesture Q was a 60 s smoothing and hand press gesture while Gesture S was a smoothing gesture alone. Prior to each application, subjects cleansed their faces and completed a self-assessment questionnaire. During the procedure, subjects were fitted with a portable electroencephalogram (EEG). A beautician applied a cosmetic product to the eye and cheek area based on specific gestures (P/R control gesture followed by Q, or S). EEG measurements were taken before, during, and after the application. Subsequently, participants filled out another self-assessment questionnaire. IMPORTANT
resultsGesture Q was identified as less stressful, more comfortable during application, and higher positive valence after application which was aligned with self-perception questionnaire results. The portable EEG analyser further revealed the evolution of emotions during application whereby Gesture Q induced a constant and positive evolution of emotion after 20 s, while Gesture S showed a slight decrease of stress only after 40 s and induced a dominant feeling of lower valence after application, associated with a negative feeling.
conclusionThe portable EEG analyser showed high potential to capture and differentiate between emotions during the beauty experience. Gesture Q positively influenced the emotional state of subjects, which was complimentary to what subjects reported. Emotions captured during the evolution of gestures helped identify key moments of application. Combined with the self-questionnaire, these findings contribute to the development of user experience.
