Abstract Human skin is often exposed to sunlight and pollution so it looks dull and lacks shine. This causes a buildup of dead skin cells so it is necessary to exfoliate using a Scrub. The Scrub material that can be used is salt. The purpose of this study was to determine the effect of adding salt concentration on the physical properties of the face Scrub gel preparation Gracilaria sp. The method used in this study was a completely randomized design (CRD) experiment with four treatments and five replications. The treatment used was administration with different salt concentrations, namely P0 (0%), P1 (10%), P2 (20%) and P3 (30%). The main parameters observed were the physical properties of the facial Scrub gel preparation which included pH test, homogeneity test, viscosity test, organoleptic test, specific gravity test. While the supporting parameters are irritation test and SEM-EDX test. The results showed that the administration of different salt concentrations had a significant effect on the physical properties of the facial Scrub gel preparation. The best formulation was in the P2 treatment (20% salt).
