The Effect of Ultrasound Wave to Improve Skin Turgor

Abstract

The decrease of facial skin turgor causes the decrease of skin elasticity. The quality of skin depends on many factors; namely internal and external factors. According to the theories, the process of skin aging is associated with the decreasing production of metalloproteinases (MTP) by the cells and the decrease of proteins metabolism, known as Heat Shock Proteins (HSP) in the skin. It can cause elasticity of the skin, which is called turgor. If elasticity of skin decreases, it can trigger unclear leveling between epidermis and dermis, epidermis layer will push the dermis layer; hence, nutrition supply to epidermis layer will decrease and many problems will happen such as the appearance of wrinkle. This research examined the benefits of ultra sound wave (US) with 3 MHz of frequency to improve skin turgor in the facial area, in which it was expected that with ultrasound waves, it can activate HSP and MTP. US was applied continuously, with intensity of 1-1.5 w/cm 2 , and in 10 minutes duration, the frequency of use was twice a week. This research was experiment, with quasi-experimental approach and design of pre and post test with control group design. This research was conducted at Mini Clinic for Skin Care at clinic Bunda Sella, Karangasem, Surakarta. The samples were taken by purposive sampling. There were 24 respondents who were screened based on inclusion criterias. The respondents were divided into two groups. Statistic test by using Wilcoxon test was applied on each group and in order to analyze the differences between two groups, the research used Mann Whitney Mann Whitney test. There was an effect of ultra sound to reduce skin turgor. The mean value of turgor for experiment group was 4.41 and control group was 0.5. The statistic result for treatment group: p-value was 0.0011 and pvalue was 0.039 for the control group; and there were different results of statistic test between

two

groups and the p value was 0.0021. The conclusion of this research showed that ultrasound wave can provide a positive influence on the facial skin rejuvenation especially to improve skin turgor.
