Under-Eye Night Serum. Retinol has been shown in several clinical trials to combat common skin-ageing concerns such as facial wrinkles, lines, folds & a loss of firmness by stimulating collagen & hyaluronic acid production. Retinol has also been proven to improve skin clarity & texture, promote anti-pigmentation plus demonstrate anti-acne & pore-minimizing effects, all leading to a more youthful skin appearance. Retinol Eye TR is a specially formulated retinol serum for use in the delicate under-eye area. Containing highly stable, encapsulated all-trans retinol at 0.1% concentration, Retinol Eye TR melts into the skin & leaves a non-greasy powder dry finish. It does not irritate like regular retinol products because of the unique time-release (TR) formula. Paraben & fragrance free.
