Offering up to 48 hours of hydration, the LANEIGE Water Bank Blue Hyaluronic Gel Moisturizer saturates the skin in refreshing, soothing moisture. The aqueous gel is powered by proprietary blue hyaluronic acid, an amplified form of hyaluronic acid that has been through a double fermentation process with deep-sea algae and microfiltered for refinement. These molecules are 2000 times smaller than normal hyaluronic acid, meaning the formula is able to deliver intense and long-lasting moisture to the skin. Supported by a cooling mint leaf extract to help minimise excess sebum and unwanted shine, ideal for oily skin types, the serum promotes a balanced-looking complexion.
