*¹ Move the device in lifting motions

*² Up to the stratum corneum (outermost layer of the skin)

*³ Lift care performed with the D×LIFT mode, warming the entire stratum corneum while moving the device in lifting motions

*⁴ Care performed by cooling the skin

*⁵ General term for care performed either while the device lifts the skin or by moving the device in lifting motions

*⁶ RF (Radio Frequency): Overall satisfaction with warming effect; EMS: Overall satisfaction with facial muscle care. Values rounded to the second decimal. Test overview/conditions: Devices used: YJFM18N, YJFA1T. After applying cosmetics, DYHP mode of YJFM18N (levels 1–3) was applied to half the face and D×LIFT mode of YJFA1T (levels 1–6) to the other half, each for 2.5 minutes. Effect was rated on a 7-point scale from “no effect at all” to “very noticeable effect,” and averages were calculated. Results expressed relative to YJFM18N = 1. Participants: 13 women, ages 30–50. Measured by Facial Muscle Research Institute. Individual results may vary.

*⁷ Test method: Various solutions containing active ingredients applied to the forearm and used for 1 minute; penetration into the stratum corneum was compared with and without device use. Participants: 10 men; Vitamin C derivative, tranexamic acid (avg. 38.4 ± 7.4 years), niacinamide (avg. 26.4 ± 4.0 years). Results may vary between individuals.
