| dc.description.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. | in_ID |
