The EMS beauty device massages the skin surface and the muscle layer in the skin through a combination of medium frequency electrical stimulation and physical stimulation that are known to effective in skin rejuvenation. In this study, the EMS beauty device reproducing Petrissage massage method and functional cosmetic containing adenosine were used. For four weeks of study period, the EMS beauty device and the functional cosmetic were applied together to the test group with 11 women, whereas only the functional cosmetic was applied to the control group with 11 women. The EMS beauty device was applied for 10 minutes every night after cleansing face to the test group only, and the functional cosmetic was applied every morning and night after cleansing face to both groups. The skin improvements were evaluated after two and four weeks from the first visit (baseline) by mechanical measurements. As the evaluation results, significant (p<.05) improvements of skin elasticity (R2 and Mean CoR), skin sagging, and double chin lifting showed in the test group compared with the baseline, and compared with the control group. Therefore, the EMS beauty device is considered to be effective to improve skin features related to skin aging. And this study may expect to be useful data for global advancement and enforcement of market competitiveness of K-beauty industry and to be a foundation for further in-depth study.
