4D Hyaluronic Serum delivers megadoses of hydration with a multi-dimensional approach that works both instantly and long term. This lightweight water-gel serum penetrates deeply to restore moisture and water balance, plump skin and relieve dehydration. By supporting optimal hydration pathways, it smooths fine lines, strengthens the barrier and revitalises the complexion. Skin is left supple, refreshed and deeply hydrated, with a radiant and youthful glow.

How It Works

4D Hyaluronic Serum harnesses four advanced forms of Sodium Hyaluronate, each selected for its unique molecular weight and affinity with the skin. This multi-dimensional hydration system creates a four-dimensional moisture network, helping reduce transepidermal water loss while delivering complete, multi-layer hydration. Ultra-high molecular weight Sodium Hyaluronate Crosspolymer forms a protective film on the skin surface, high molecular weight molecules nourish and hold water, Sodium Acetylated Hyaluronate adheres to the stratum corneum for lasting hydration and ultra-low molecular weight Hydrolyzed Sodium Hyaluronate penetrates deeper to support visible elasticity, leaving skin plump, smooth and supple.
