The CeraVe Hydrating Serum enriched with Hyaluronic Acid ensures that facial skin remains moisturized for a full day. This serum aids in softening the skin and supports the restoration of the skin's protective barrier. Key components of this formula include three vital ceramides that assist in mending and sustaining the skin barrier’s functionality, hyaluronic acid for lasting hydration, and vitamin B5, which calms and aids in repairing barrier function. Utilizing MVE® technology, this patented method allows for a prolonged release of active ingredients, thereby ensuring hydration persists for up to 24 hours. Additionally, this non-greasy serum is rapidly absorbed and is formulated to be non-comedogenic, meaning it won't clog pores. *Tested instrumentally.
