The COSRX Hyaluronic Acid Hydra Power Essence is a deeply hydrating serum-like essence formulated with high concentrations of hyaluronic acid and sea buckthorn water to deliver intense moisture and nourishment to the skin. This lightweight, fast-absorbing essence helps to plump the skin, improve elasticity, and leave the complexion soft, smooth, and dewy without heaviness or stickiness.
After cleansing and toning, apply a small amount of the essence to your face, gently patting it in until fully absorbed. Follow with your favorite moisturizer to lock in hydration. Use morning and night as part of your daily skincare routine, especially when your skin feels dry or tight.
COSRX is a Korean skincare brand known for its science-based, minimalist approach to effective skincare. The name “COSRX” comes from a combination of “cosmetics” and “prescription (Rx),” reflecting the brand’s goal to provide customized solutions for various skin concerns using short, clean ingredient lists and high-performance actives. COSRX has built a loyal global following for its no-frills yet powerful formulations that deliver visible results without irritating the skin.
The formula includes Hippophae Rhamnoides Water (sea buckthorn water), sodium hyaluronate (a stable form of hyaluronic acid), betaine, panthenol, allantoin, and arginine. These ingredients work together to replenish moisture, soothe irritation, and strengthen the skin barrier.
This essence is suitable for dry, dehydrated, combination, and sensitive skin types. It’s especially beneficial for skin lacking moisture or experiencing tightness or flakiness. However, it may not be ideal for very oily or acne-prone skin types that prefer ultra-light textures, as its hydrating finish may feel slightly rich for some.
