Don't be disturbed by this attractive design as this serum is hard-working stuff. To use, just remove the onyx cap and use the metallic roller to apply - this is really comfortingly cool to the touch. You will absolutely feel that it's working instantly as you feel it tightens and rehydrates your skin with the complex of collagen proteins enriched with Plankton extracts, Red Algae, and Hyaluronic Acid.
