This Plexaderm Rapid Reduction Serum duo instantly and temporarily improves the appearance of under-eye circles. The new tube was designed for ultimate comfort and control; the soft material makes it easier to dispense just the right amount of serum. The formula contains titanium dioxide to temporarily improve the appearance of dull skin tone and under-eye circles, plus argireline to temporarily improve the appearance of fine lines and wrinkles.

In a test with subjects using Rapid Reduction Serum just once, it temporarily reduced the appearance of wrinkles and crow's feet by an average of 81% after 10 minutes.

How do I use it: Wash and dry skin thoroughly. Apply a small amount of serum (start with about half the size of a pea) to problem areas, gently dabbing to create a thin even application. Be careful to avoid contact with eyes. Remain expressionless for 10 minutes while the product sets.
