초음파 사용이 건강한 여성의 피부 탄력과 피부 깊은 탄력 개선에 미치는 영향 = Effects of Ultrasound on Skin Elasticity and Elasticity of Deeper Skin in Healthy Women

다국어 초록 (Multilingual Abstract)

Purpose : Aging is reflected on the face of women due to the depletion of collagen and hydration in the facial skin overtime. This study investigated the effect of multiple SONO® ultrasound for a 4-week period on the skin health by measuring the skin elasticity and deeper skin elasticity in the tested women subjects.
Methods : Twenty healthy women were recruited for this experiment. All the participants applied multiple ultrasound device (SONO®) during this experiment. The SONO® device was set to ANTI-AGING function and five power steps such as 1, 3, 10 and 17 ㎒ were used during this experiment, and directly contacted with the facial skin. Specifically, the probe was contacted with the entire face except for the nose and eyes for 10 min on each side of the face every day and repeated for 4 weeks. The skin elasticity and the elasticity of deeper skin were measured at three times (0, 2, 4 weeks) using a Ballistometer and dermal torque meter, respectively. The one way repeated ANOVA was used to compare the skin elasticity and the elasticity of deeper skin among three times (0, 2, 4 weeks).
Results : The skin elasticity (p<.05) and elasticity of deeper skin (p<.05) were significantly increased at 2 weeks and 4 weeks of intervention compared to that at 0 weeks. For the skin elasticity, there was no significant difference between 2 and 4 weeks of intervention (p>.05). For the elasticity of deeper skin, it increased significantly at 4 weeks compared to 2 weeks of intervention (p<.05).
Conclusion : These findings suggest that applying multiple SONO® ultrasound to the facial skin of healthy women for 4 weeks, can increase the skin elasticity and elasticity of deeper skin by supporting epidermal hydration and dermal collagen production.
