Determination of the Efficacy of Slendertone® Face to Tone the Muscles of the Face and Reduce the Signs of Facial Aging
The purpose of this study was to determine the efficacy of Slendertone® Face™, to tone the
 muscles of the face and reduce the signs of facial aging among the following characteristics:
 radiance, tone, lift, firmness and complexion, following a 12-week programme of facial muscle
 toning. Slendertone® Face is a neuromuscular electrical stimulation (NMES) device which
 features a headset unit designed for application to the face for facial toning. The purpose
 of the headset is to locate and support a pair of stimulation electrodes on each side of the
 face, over the facial nerve just anterior to the ear.
The trial was planned with 100 healthy female volunteers between 25 and 55 years of age.

 Treated group: Face device 20 minutes per day, 5 days per week for 12 weeks.

 Control group: No NMES.

 Both Groups: No changes to usual beauty routine, or use of beauty products with an anti-aging
 claim, or changes to usual diet or exercise habits over the course of the 12 week study
 period.

 Ultrasound measurements of the zygomaticus major muscle were planned at Baseline, and at the
 end of Weeks 6 and 12.

 Psychometric questionnaires at Baseline, end of Weeks 6 and 12.
