Caffeinated Skincare Development and Optimization: Upcycling Spent Coffee Grounds Into Natural Exfoliants.
Article in Journal of cosmetic dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSpent coffee grounds (SCG) offer significant ecological and cosmetic potential. The conversion of SCG into safe and efficient cosmetic products promotes all aspects of sustainability and circular practices within the cosmetic industry.
aimsThis study aimed to show the interdisciplinary bottom-up approach within two focal points: demonstrating the use of upcycled materials in high-value natural products and understanding how base formulations' content and properties influence the characteristics, consumer preferences, and clinical efficacy of exfoliant products.
methodsMethods included characterization of SCG, development of formulations, physicochemical characterization, stability testing, and the estimation of carbon dioxide emissions of the preparation process. Consumer panel testing optimized the most preferred sensory characteristics of exfoliant products chosen for clinical evaluation. Transepidermal water loss measurements assessed skin barrier disruption and recovery after the use of exfoliant formulations and after the application of hand cream.
resultsThe SCG found richest in bioactive substances was incorporated in three concentrations into seven exfoliant formulation bases. Stable formulations were assessed by a consumer panel, and four formulations with the best sensory characteristics were ointment-based (F1) with 5% and 10% SCG, cream-based (F6), and gel-based (F11) with 5% SCG. The ointment-based exfoliant showed no significant changes after application or after hydration cream. Aqueous formulations (F6 and F11) temporarily disrupted skin barrier function, but full recovery occurred within 6 h of hand cream application.
conclusionBy utilizing SCG, high-quality cosmetic formulations can be created that are well-received by consumers. Clinical findings suggest that different exfoliant formulations may suit various skin types.
