In this study we carried out the experiment with 14 women in their thirties and forties who are in the process of aging over four weeks by two times a week in order to observe the effect of high frequency therapy and ultrasound therapy in skin's pigmentation and wrinkle treatment. We applied high frequency therapy at the frequency of 0.3MHz, 60W/㎠ and ultrasound therapy at the frequency of 1MHz, 3W/㎠ for about 15 minutes respectively, and got the result like following. Both high frequency therapy and ultrasound therapy got the improvement of pigmentation on face compared to before use but the effect of high frequency therapy was a bit higher than ultrasound therapy. In the aspect of the effect of wrinkle treatment, high frequency therapy and ultrasound therapy showed similar result but high frequency therapy was a little more effective. It is considered that pigmentation and wrinkles were treated as cells are revitalized by the heat treatment, heat action, chemical action and physiological effect. Consequently high frequency therapy and ultrasound therapy influenced positive affect on the treatment of pigmentation and wrinkles in the experiment of this study and it is expected that more clinical studies will be conducted with proper use of beauty instrument as people show interests on skin care.
