The antibacterial properties of the different components of anti-acne sheet masks will be determined through the diameter of the inhibitory zones of all serums of the different sheet masks against S. aureus by calculating the diameter of the zone. The diameter can be calculated by drawing contours and setting the appropriate threshold value. It can also determine if the different serums of the sheet masks can eliminate S. aureus using the calculated zone of inhibition and the appropriate standard values. The calculated zone of inhibition will be compared and analyzed using t-test. The different serums will be compared using the analysis of variance (ANOVA). Certain values are gathered from the standard given ranges of antimicrobial agents and their specific zone diameter effectiveness.
