Details

A vitamin C serum for skin that looks dull or uneven in tone, or feels dry. It is a morning step, applied before moisturiser and SPF.

RATIONALE's skin-identical antioxidant complex, built around vitamin C, helps defend skin against everyday oxidative stress and helps it look brighter and more even. Supporting antioxidants add a second layer of defence against environmental aggressors, while the water-and-oil base adds hydration.

Facialist's note: smooth 2–3 drops over face, neck and décolletage each morning, then follow with moisturiser and RATIONALE #3 The Brilliance Tinted Serum or your usual SPF.
