Bonus Gift with Tru-North full length Mattress Pad Purchase. (Tru-North Basic series and Economy series is not included for this offer) The Anti-Aging face Mask is an all north pole magnetic face mask. Reduce stress and REVITALIZE YOUR AGING EYES. (not valid with Tru-North Basic Series) Reduce puffiness and fine lines. During the aging process facial muscle fibers lose their youthful elasticity and firmness. The fibers deterioate causing the overlying skin to sag and droop. As the skin ages, the collagen molecules break down, which leads to formation of fine lines and wrinkles. Enjoy the benefits of magnetic therapy while you sleep. Many users indicate the sleep mask is helpful for stress, allergies, sinus, and sleep problems. Use the black side of the face mask (north pole) against the face.
