Shiseido Bio-Performance Intensive Skin Corrective Program is a unique skincare program designed to repair damaged or stressed skin that can no longer be maintained by standard skincare regimens. This two-step intensive system, which takes the place of an everyday skincare regimen, helps revive and restore distressed skin in only 14 days. It strengthens the barrier function of the complexion by recharging the balance of calcium and magnesium ions to alleviate dryness, roughness and dullness.
