Olive Squalene is able to mimic the skin's natural squalene, which is the skin's main lipid, emollient, built-in moisturiser and antioxidant. As our natural squalene diminishes over time, our skin starts to dry out and signs of ageing appear. Olive Squalene works to replace this lost hydration and antioxidant protection, helping to combat dry skin and keep it smooth and supple.
