Results : In the self-evaluation, 86% of subjects reported looking better when asked immediately after and 74% did so three days after the treatment. Improvements in eye area and lifting were noticed by more than half of the subjects, but were short-term. Feeling of refreshment and improvement of the entire face and complexion lasted for 3 days. In the photo evaluation, the “correct response rate” was significantly higher than the “incorrect response rate” for overall impression, skin luster, and skin firmness. Female assessors had significantly higher “correct response rates” than male assessors for the four items of impression, luster, firmness, and sagging. The “correct response rate” of the photographs of the positive rating subject group was significantly higher than that of the negative rating subject group for the general impression, and a higher trend was also seen for skin firmness.
