Key Ingredients

• Sodium Hyaluronate (4000ppm): A natural moisture-retention ingredient that deeply hydrates and smooths the skin. Skin feels plumped and stays hydrated throughout the day without feeling heavy.
• Hippophae Rhamnoides Water (84.8%): Also known as sea buckthorn water, it protects skin cells from damage and stress with fatty acids. This helps skin stay resilient and look healthier over time.

Skin Concerns Addressed

• Primary: Dehydration, dryness, fine lines
• Secondary: Rough texture, dullness
• Supporting: Sensitivity, irritation

This serum is formulated specifically to target dehydration and dryness. If your main concern is lack of moisture, this addresses it directly. For textural issues or deep wrinkles, pair with a retinol or AHA product.

Why This Serum Works

This essence contains 4,000ppm of sodium hyaluronate a concentration high enough to deliver intense, lasting hydration without oil or heaviness.

On top of that, the formula uses sea buckthorn water, which protects skin cells from damage and stress with fatty acids, supporting a healthy skin barrier.

What makes this more effective is its short and simple ingredient list, excluding unnecessary irritants that could trigger sensitivity or breakouts.

Together, these factors create a formula that intensely hydrates, protects, and soothes skin, making it ideal for daily use on all skin types.
