Hyaluronic Sea Serum

$ 88.00

Serious hydration for all skin types.

This fast-absorbing, concentrated serum smooths the appearance of fine lines and wrinkles. OSEA's newly upgraded formula, powered by two molecular weights of hyaluronic acid, seaweed and snow mushroom, works to restore and maintain optimal moisture levels, keeping your skin hydrated any time of day. Clinically and dermatologist tested.

Clinically Proven to*:

  • Instantly increase hydration
  • Deliver a lifted and firmer look
  • Fill the look of wrinkles
  • Minimize the appearance of all lines


This lightweight, non-greasy, moisture-boosting serum smoothes wrinkles and fine lines and replenishes dry, thirsty skin. Hyaluronic Acid, nature’s most powerful moisture magnet, floods skin to deliver intense moisture that swiftly plumps for a more youthful, dewy glow. Hyaluronic Acid attracts up to 1000X its weight in water, strengthening the skin’s moisture barrier for visibly improved firmness and elasticity. Age-defying seaweed extracts boost skin with antioxidants, vitamins, and minerals. This high-performance serum absorbs instantly, leaving a velvety-soft, luminous finish.


After cleansing and misting, apply two pumps to face, neck, and decolleté. Use morning and night or anytime skin needs an intense moisture boost. Follow with OSEA moisturizer of choice.
