Rodan + Fields Contour Neck Treatment - NEW IN BOX - 50mL What it is: A neck care solution rooted in dermatological science that lifts, smooths, firms and tightens while supporting collagen depleted skin. This one product is specifically formulated to prevent (in your 20’s and 30’s) and address (for the rest of us) the root causes of neck aging. Why you need it: The skin on your neck and décolleté is thinner than the skin on your face, which makes them a prime target for those sneaky types of neck and décolleté aging; discoloration, tech neck, sagging, wrinkles + cross hatching, and double chin.
