Product Description Powerful day & night serum formulated with Dr. Perricone’s next generation polyamine technology to deliver a visibly dramatic lifting effect, leaving the skin looking smooth & radiant. Supports the skin’s moisture barrier & visibly improves skin plumpness, strength, cushion, bounce & resiliency. Due to the unique technology of our Encapsulated Retinol, the formula may feel slightly gritty upon initial application. This is normal. As the product is massaged into the face, the encapsulation will break and the retinol will absorb easily into the skin. Brand Story For more than two decades, Perricone MD has been a holistic, three-tier skincare and wellness system. This consists of diet, essential dietary supplements and potent topical skincare solutions backed by powerful ingredients.
