AbstractBackgroundWith the rise in interest and demand for body contouring, beauty devices have continuously developed. Suction can aid in increasing the rate of fat breakdown by inducing a massage‐like effect, thereby increasing blood flow. Moreover, radiofrequency (RF) can boost fibroblast activity and help reduce cellulite. In addition, electrical muscle stimulation (EMS) can use electrical stimulation to induce muscle contraction, leading to an athletic, and skin elasticity‐increasing effect.AimsThis study aimed to assess the effects of body contouring, such as cellulite and swelling, in healthy Korean women to objectively prove the efficacy of an at‐home beauty device equipped with suction, RF, and EMS functions.MethodsFor 8 weeks, 21 participants used the at‐home beauty device 3 days a week on their abdomen, thighs, and left calf. Validity assessments and subjective surveys were conducted at 4 and 8 weeks, including the first visit.ResultsThe results of the validity assessments revealed that cellulite, swelling, elasticity, femoral skin texture, and dermal density were significantly (p < 0.05) improved in the experimental group compared with those at the baseline.ConclusionsThe results of this study demonstrate that the combination of suction, RF, and EMS function is effective for body skin, fat, and body shape management. For better body‐contouring effects, combining the beauty device with regular exercise and healthy eating habits is recommended.
