The Perricone MD High Potency Growth Factor Duo seeks to encourage a firmer, more lifted appearance for skin lacking visible elasticity and bounce. The serum collection features a facial serum and an eye serum, designed to be applied before your favourite moisturiser and eye cream. Set Contents: High Potency Growth Factor Firming & Lifting Serum 59ml Utilising the brand's encapsulated retinol, the unique technology promotes the illusion of collagen-rich skin with a plumped appearance. The formula may have a gritty texture to begin with but once massaged into the skin, the encapsulation breaks down as the retinol melts onto the skin. High Potency Growth Factor Firming Eye Serum 15ml Lightweight but powerful, the eye serum is formulated with advanced polyamine technology to create a lifting effect around the eyes. The formula works to nourish and smooth the look of fine lines and texture around the eyes while lending a brightening finish.
