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 MHz 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.

Methods: The present author performed once a week and total 4 times of MTS treatment. The treatment time took about 5~10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, simple distilled water was applied after MTS and in the experimental group, CCIS distilled herbal medicine was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results: In the case of the test group, there was a significant decrease in pore size and there was a significant increase in U-zone oil, skin tone and elasticity. The test group using distilled herbal medicine showed a significant effect on facial skin compared to the control group using only simple distilled water. Conclusion: Distilled herbal medicine showed an effective action on facial skin. In the case of CCIS distilled herbal medicine, it was found to have a significant effect on U-zone oil content, skin tone, pores, and skin elasticity.

Purpose: The mass of facial muscles can be increased through exercise, as is also the case for muscles in the extremities. This systematic review was conducted to investigate the effect of facial exercises on facial muscle strengthening and facial rejuvenation, focusing on recent studies. Methods: A literature search was performed using the PubMed, ScienceDirect, and Web of Science databases. The quality of the trials was evaluated according to the PEDro scale. In total, 11 studies were included in this review: four studies on facial exercise for facial rejuvenation and seven studies on strengthening the muscles of the face. Results: Facial exercises for facial rejuvenation increased the mechanical properties and elasticity of the skin of the face and neck, the thickness and cross-sectional area of the facial muscles, and the fullness of the upper and lower cheeks. Conclusion: A study aimed at strengthening facial muscles showed improvements in labial closure strength and tongue elevation strength. Despite the positive results for facial rejuvenation and muscle strengthening, the level of evidence was low. Therefore, in future research, it will be necessary to investigate the effects of facial exercise in a thoroughly controlled experiment with a sufficient sample size to increase the level of evidence.

Background Morphological changes that accompany aging, such as wrinkles and skin laxity, are particularly prominent on facial skin. Recently, facial rejuvenation using the hydrofilling effect of hyaluronic acid (HA) filler has been employed for improvement of skin texture. In this study, we studied rejuvenating effects of stabilized HA (Restylane Vital) through direct intradermal injections. Methods A total of 30 female patients underwent a series of procedures on face, including three sessions at intervals of four weeks. A total of 2 mL of Restylane Vital was injected along the whole face using an automatic injector. Improvement of skin surface roughness, elasticity, brightness, moisture, and fine wrinkles was evaluated. Patient satisfaction was evaluated, and pictures of patients were taken at each visit and 6 months after last treatment session. Scoring for each patient was performed by three doctors according in five subjects. Moisture, oil and elasticity were measured before the procedure and before the last treatment in 10 patients. Results The majority of patients (77%) were satisfied with the therapeutic outcomes. Approximately 66% of patients responded that the effects of this procedure persisted for longer than four months, and the majority of patients (77%) wanted to undergo this procedure again and would recommend this procedure to acquaintances. Regarding doctors' evaluation, scores for improvement of skin surface roughness, elasticity, and brightness were significantly higher than those for improvement of moisture and fine wrinkle. Conclusions Intradermal injection of HA can have a rejuvenating effect on dry and tired facial skin, especially in improvement of skin surface roughness.

Background: Age-related changes in facial skin is a major concern in women. This study aimed to objectively evaluate normal skin elasticity and age-related differences in the faces of East Asian women. There are no standard values for data related to normal skin on East Asian women. Methods: We studied 129 healthy East Asian women without a history of cosmetic procedures or surgeries. Skin elasticity was assessed at the cheek and lower eyelid points, which were assessed on both the right and left sides of the face. Results: The age of the subjects showed significant negative correlations with the R2 and R7 parameters, which represent skin elasticity after deformation. Conclusion: We therefore concluded that the primary decrease in skin elasticity in East Asian women occurs in the midface region.

Recently, the beauty industry has implemented personalized services based on skin big data. To increase competitiveness in the beauty industry, systematic data measurement and evaluation indicators are necessary to select data and obtain necessary knowledge. In response, this study sought to stably enhance the accuracy of skin diagnosis based on satisfaction and reliability. To this end, the research was conducted through focus group interviews (FGI), a case study of brands, and analysis of prior research results. In particular, as a result of analyzing keywords that classify skin types by brand, common survey items for skin types were oiliness and using moisturizer, cosmetic use and vascular of skin, external stimulus and blemish & freckles, facial wrinkle, outside activities, self-consciousness, and smoke. In additioin to the common questions of the preceding study and the brand survey items, the questions concerning complex skin types, seasonal change, facial color, wrinkles and elasticity were added, and the questions were presented in a total of 40 items. In particular, it suggested that skin measurement could be conducted by focusing on elasticity and pigmentation items by reflecting the results of prior research and the opinions of FGI, and based on this, a customized service with high satisfaction and high accuracy of beauty care based on this could be proposed. We hope that this study will facilitate active self-care by providing more satisfying skin stones and personalized cosmetics proposals, thus laying the foundation for the further development of the cosmetics industry.

Objectives : The purpose of this study was to investigate the efficacy of Abelmoschus manihot (A-M) on the facial skin by observing the changes in the skin caused by continuous use of the essence containing A-M. Methods : Fifty-one participants were enrolled, 38 were classified as experimental group and 13 were classified as control group. Before the beginning of the test, the skin condition of the participants was investigated with the facial analyzer. An essence containing A-M was provided to the experimental group, and an essence base not containing Abelmoschus manihot was provided to the control group. Participants were asked to use the product in the morning and evening after washing their face. We checked the skin change status every 2 weeks and performed the test 3 times for 6 weeks. Results : In the case of t-zone oil and pores, there was a significant decrease in the experimental group. In the case of moisture, a significant increase was observed in the control group, but the significance was significantly increased when the essence containing A-M was used. In the case of elasticity, it was found that the experimental group continued to increase with the period of use. Conclusion : It is thought that the essence containing A-M will be effective in preventing skin aging through the reduction of t-zone oil, the size of the pores, and the increase in moisture and elasticity.
