respectively. Physical stability test was conducted by cycling test for 6
cycles. The physical properties of the preparation was tested before and after
storage include adhesion, dispersive power, pH, viscosity and time to dry.
Antioxidant activity tested with DPPH method. Based on test results obtained
physical stability, third-formula gel mask physically qualified and stable,
except for the dispersive power. Antioxidant activity decreased after the
