Abstract

The increasing concern over the long-term use of synthetic cosmetic ingredients has driven the development of natural-based
skincare products. Seaweed (Eucheuma spinosum) is an abundant marine resource in Indonesia rich in bioactive compounds with
potential cosmetic benefits. This study aimed to formulate a peel-off gel mask containing E. spinosum extract and to evaluate its
physical quality and consumer preference. Seaweed was extracted by maceration using 96% ethanol and incorporated into gel
formulations at three concentrations: 3 g (F1), 5 g (F2), and 7 g (F3). Physical quality tests included organoleptic evaluation, pH,
homogeneity, spreadability, viscosity, drying time, stability using a cycling test, and hedonic (preference) testing. All formulations
met acceptable cosmetic standards, showing skin-compatible pH (4.5–6.5), good homogeneity, spreadability of 5–7 cm, viscosity
within 5,183–6,017 cPs, drying time of 18–22 minutes, and stable characteristics during storage. Hedonic testing indicated that
formulation F1 was most preferred by panelists and demonstrated the best overall characteristics. These results suggest that E.
spinosum extract is a promising natural active ingredient for peel-off gel mask formulations.
