The COSRX Hyaluronic Acid Hydra Power Essence is a skincare product formulated with key active ingredients aimed at providing intense hydration to the skin. The essence contains Sodium Hyaluronate, which is a salt form of Hyaluronic Acid. Hyaluronic Acid is a glycosaminoglycan that naturally occurs in the human body and is a powerful humectant, capable of holding up to 1000 times its weight in water. This property allows Hyaluronic Acid to attract and retain moisture in the skin, keeping it plump and hydrated. In addition to Sodium Hyaluronate, the essence also contains Hippophae Rhamnoides Water, which is derived from sea buckthorn berries. This ingredient is rich in antioxidants like vitamin C and E, helping to protect the skin from environmental stressors and promoting healthy skin cell regeneration. The antioxidant properties of Hippophae Rhamnoides Water complement the hydrating effects of Hyaluronic Acid, resulting in a more radiant and youthful complexion. The formulation of the COSRX Hyaluronic Acid Hydra Power Essence has a slightly acidic pH, which is beneficial for maintaining the skin's natural protective barrier. The essence has a lightweight and non-greasy texture, allowing for easy absorption into the skin. This quick absorption enhances its bioavailability, ensuring that the active ingredients can penetrate deep into the skin layers to deliver optimal hydration.
