Development And Characterization Of Peel-Off Gel Masks Incorporating Activated Charcoal And Salicylic Acid For Enhanced Skin Radiance And Rejuvenation

This study aims to develop and characterize peel-off gel masks incorporating activated charcoal and salicylic acid for enhanced skin radiance, smoothness, and rejuvenation. The masks were formulated using polyvinyl alcohol as the primary film-forming agent, with hydroxypropyl methylcellulose and gelatin serving as gelling agents, alongside other components such as solvents and preservatives. The physicochemical properties of the formulations were evaluated, including organoleptic characteristics, homogeneity, pH, spreadability, and drying time. Additionally, skin irritation and hedonic tests were conducted to assess safety and user satisfaction. Results indicated that all formulations were homogeneous and free of coarse particles, with suitable pH levels to enhance the efficacy of salicylic acid for skin exfoliation. The formulations demonstrated good spreadability, allowing for even application on the skin, and drying times ranged from 17 to 23 minutes. The masks exhibited high user acceptability, with formulations containing both activated charcoal and salicylic acid showing significant improvements in skin smoothness, brightness, and tightness. The study concludes that these peel-off gel masks are effective and safe for enhancing skin radiance and rejuvenation. Among the tested formulations, F8 was the most favored, making it a strong candidate for further development and potential market introduction.
