A high-performance serum-moisturiser hybrid, MAC’s Hyper Real Serumizer™ Skin Balancing Serum locks makeup into place for up to 12 hours. Delivering a refreshing boost of hydration, the formula creates a radiant, petal-soft canvas ready for makeup application. MAC’s Pro-4 Power Infusion Matrix™ utilises a blend of hyaluronic acid, niacinamide, ceramides and Japanese peony extract to help moisturise dryness and visibly refine the skin's texture. Designed to be used with or without makeup, the artist-approved serum nourishes the skin barrier function, while light-diffusing pearlescent particles encourage a glowing look. Its featherlight texture absorbs into the skin with a non-greasy feel.
