This is a research on the effect of formula containing of vitamin A and vitamin E(Frie of oil, Wlter Bouhon GmBH, Germany) on the strech mark. The participants of this study were 20 women at the age of early 20s through middle 20s, who had strech marks that had been over 1 year at the minimum and at less than 5 years at the maximum. Formula containing of vitamin A and vitamin E was applied with typical massage to strech marks for 4 months and twice per day. Improvement resulting from the application was evaluated through observation with the naked eye, questionnaire survey, and the equipment used was DermaScan C Ver3(Cortex Technology, Denmark). The experiment showed that parts cared with formula containing of vitamin A and vitamin E had less strech marks than those control site(treated with jojoba oil).In around 2 months since the use of the formula containing of vitamin A and vitamin E, the tensile of the skin increased and deep wrinkles on the chapped surface became unclear, and in around 4 months the tensile force again decreased and the resilience of the skin increased, and the ultrasonic image showed the decrease of echo pore-zone, which indicates the degree of tissue damage. According to the result of the questionnaire survey, strech marks of less than red strech marks of primary stage were improved more quickly than white strech marks and all participants appeared to experience improvement. The result shows that if this formula is used continuously over 4 months, it reduces strech marks and increase the resilience of the skin. It is considered necessary to continue objective measuring and research concerning strech marks.
