Q
Please explain how to use InnerSignal.
A

After washing your face, immediately apply Rejuvenate Extract. Then, use Rejuvenate Lotion, Rejuvenate Milk, and Rejuvenate Cream. These skin care steps will enable Otsuka's own active medicinal ingredient, Energy Signal AMP (disodium adenosine phosphate OT), to repeatedly penetrate the skin, promoting a fresher, healthier, and clearer complexion.
