Give your skin the power to rehydrate itself and an instant hydration boost with the Clinique Moisture Surge 72hr Auto-Replenishing Hydrator. Delivering up to a 152% moisture boost, your skin will feel twice as hydrated than normal. Effects last 72 hours, even after cleansing your face. Formulated using unique Auto-Replenishing Technology, the Hydrator helps your skin to develop an internal water source to constantly maintain hydration. The complex leaves you with a healthy-looking, plump complexion and a dewy glow. A matrix of polymers and humectants help your skin to seal in moisture and reduce water loss. Added hyaluronic acid acts like a sponge in attracting hydration from the external environment into the surface layer of your skin. Activated aloe vera helps to repair damage and acts as a powerful anti-inflammatory. It may also help to treat conditions such as acne, dry skin and psoriasis. Can be used over or under makeup or as a mask left on for 5 minutes. For an added hydration boost, apply with your usual moisturiser.
