This research was implemented to college students who have trouble with Grade 3 and Grade 4 acne skin based on KGAS standard. And the survey is given to all participants to find their traits, way to use cosmetics, and face-washing habits.

This may cause their acne get worse therefore they need to be trained proper facial washing instruction. Secondly, these participants’ moisture content ranges from minimum of 34.9±10.4 to 48.6±15.4 and TEWL ranges from 9.5±2.7 to 11.6±4.5. The sebum excretion ranges from 11.0±10.8 to 29.9±17.2, erythema index ranges from 334.0±48.3 to 462.4±157.8, and melanin index ranges from 129.6±17.6 to 279.7±83.4.

However, it shows similar result as G2 on both chicks yet TEWL decreases in all four areas which simply mean that the G3 is more effective than G2 in terms of TEWL. Sebum reductionon G3 works the best as time goes by. It is thought that Sebum reduction influences on infection relive and this results erythema to improve. The pigmentim provement shows well on chin area. Lastly, the observations of using this product are followings; forming well, easy to rinse, Removing make-up residue well.
