Fourteen subjects completed the trial, while 1 was excluded during follow-up. The median age was 38.8 years
(range, 25∼51 years). One subject was excluded from the
analysis because of weight loss of 5 kg.
Mean body weight at baseline, week 3, and week 6 was
63.49, 63.71, and 63.71 kg, respectively (p>0.05) (Fig. 2).
Cellulite according to the standard visual scale graded by
3 independent investigators improved significantly over 6
weeks (Fig. 3). Compared to baseline, the mean score decreased
0.49 points (19.8%) at week 6 (p<0.05). The
mean circumferences of the thigh and most proximal site
of the upper arm also decreased significantly by 0.7 cm
(1.7%) and 0.8 cm (2.3%), respectively, at week 6 compared
to those at baseline (Fig. 4).
Table 1 presents the results of questionnaires regarding
the subjective improvement of cellulite, degree of moisture,
elasticity, and general treatment satisfaction. The results
show that 5 of 14 subjects (35.71%) and 12 of 14
subjects (85.72%) reported improvement in cellulite at
weeks 3 and 6, respectively. No aggravation of cellulite
was reported during the trial. Moreover, 10 of 14 subjects
(71.43%) and 12 of 14 subjects (85.71%) reported improvement
in moisture, and 8 of 14 subjects (57.14%) and
11 of 14 subjects (78.57%) reported increased elasticity at
weeks 3 and 6, respectively. Regarding satisfaction, 9 of
14 subjects (64.29%) and 13 of 14 subjects (92.86%) were
generally satisfied with the product at weeks 3 and 6,
respectively.
Skin irritation occurred in 8 of 14 subejcts (57.14%) at
week 3 (Table 2). Transient flushing (21.43%) or slight
itching (21.43%) were the most common, followed by erythema
(7.14%) and prickling sensation (7.14%). At week
6, only 5 of 14 subjects (35.71%) complained of irritation;
transient flushing (21.43%) was still the most common,
followed by erythema (7.14%) and slight itching (7.14%).
The corneometer and cutometer measurements of the
thigh and medial side of the upper arm are shown in Fig. 5.
Moisture improved markedly. Meanwhile, skin elasticity
improved according to increased R2 and R7 values and
decreased R9 value, but the differences were not significant.
