Ridoki rollers are steel rollers that are used in acupressure and oriental face reflexology.  They have many "flat points" to stimulate pressure points and reflex areas of the face efficiently.  They also have the benefits of jade rollers.

They are said to stimulate the top layer of the skin, improve circulation to the skin and therefore improve its elasticity.  They are also said to be effective in preventing wrinkles and crow's feet.  Initially the rollers feel very cool to the face which draws the blood to the tissues.

In Tsuboki face massage, when rollers are used they are used before the application of oil.
