This study was intended to study the effects of improving skin moisture, pigmentation, sebum, and wrinkles using ultrasonic and high-frequency devices and to help develop the aesthetic industry. The study received final approval (YSUIRB-202304-HR-124-02) from the Research Ethics Committee (IRB) on July 20, 2023, taking into account the ethical issues of the study subjects. This study investigated the theoretical background through previous studies related to skin structure, ultrasound, and high-frequency devices, and SPSS 22.0 was used to verify homogeneity and to find out the difference in effectiveness. Women in their 30s to 50s living in Busan were selected as those with no skin history or skin disease, and those with less UV exposure in daily life, and 14 women in their 30s to 50s who met the criteria for selecting the study subjects were finally selected, and the following results were obtained. As a result of the study using ultrasonic waves, moisture and pigmentation were significant, but not in sebum and wrinkles. As a result of the study using high frequency, moisture and pigmentation were significant, but not in sebum and wrinkles. The interaction effect between ultrasonic waves and high frequency was not significant.
