The purpose of this experiment is toknow variation concentration effect of green tea etanolic extract in cream formulation to the physic andantibacteria activity especially for the acne bacteria, also in spesific concentration will be find the best ofextrac etanolic green tea leaf toward physic characteristic and anti bacterial activity.In this experiment, the thick extrac of green tea leaf is obtained by maseration way of the using 50%etanol liquid. The cream is made in five formulas that is using the extrac etanolic of green tea leaf for 1%, 3%,5%, 7% and 9% concentration with the modification formula of anti acne cream.

As biger concentration of cream extracetanolik of green tea leaf as a smaller spreading test and adhesing test but as a biger antibacterial activitytoward Staphylococcus aureus bacterial. Cream extrac etanolik of green tea leaf as a control positive in physiccharacteristic and antibacterial activity is 7% concentration.Key words : Green tea of extract etanolic, Cream, Physic characteristic test, Bacterial activity test.
