Formulation and Evaluation of Arbutin Emulgel: A Novel Approach to Combat Hyperpigmentation
Year: 2025
Type: article
Abstract: Hyperpigmentation, a prevalent dermatological concern characterized by localized or generalized darkening of the skin, significantly impacts an individual's aesthetic appearance and psychological well-being. Current therapeutic strategies often present limitations such as side effects, poor efficacy, or stability issues. Arbutin, a natural hydroquinone derivative, is recognized for its potent tyrosinase inhibitory activity, making it a promising depigmenting agent. However, its poor skin penetration and stability in conventional topical formulations hinder its therapeutic potential. This review article explores the rationale behind developing arbutin emulgel as a novel approach to overcome these challenges. Emulgels , hybrid systems combining the advantages of emulsions and gels, offer enhanced drug permeation, controlled release, and improved patient compliance due to their non-greasy and easily spreadable nature. This article delves into the mechanism of arbutin's action, factors influencing hyperpigmentation treatment, detailed profiles of key ingredients, comprehensive methodology for emulgel preparation, and critical evaluation parameters including physicochemical, in vitro, ex vivo, and in vivo assessments. The aim is to highlight the potential of arbutin emulgel as an effective, stable, and patient-friendly topical delivery system for combating hyperpigmentation.
