The Ordinary Marine Hyaluronics is a lightweight serum designed to hydrate and refresh the skin. This 30ml formula contains marine-derived hyaluronic acid, which is smaller in size than traditional hyaluronic acid and is able to penetrate deeper into the skin. This allows for a more effective delivery of hydration, leaving the skin feeling plump and moisturized. The addition of marine-derived glycoproteins helps to support the skin's natural moisturizing factors and protect against environmental stressors. With regular use, this serum can help to improve the overall texture and appearance of the skin, leaving it looking and feeling smoother, softer, and more radiant. It is suitable for all skin types and can be used morning and night after cleansing and toning.
