Description

OSEA Hyaluronic Sea Serum is small yet mighty in its age-defying power to smooth wrinkles and replenish dry, thirsty skin. Organic seaweed extracts enrich your complexion with vitamins, minerals, and antioxidants. This high-performance serum’s lightweight formula absorbs instantly with a nongreasy texture that leaves a velvety finish — without feeling sticky. The results are luminous!

What makes hyaluronic acid so effective?

Found in the skin, eyes, and connective tissue, hyaluronic acid naturally plumps your skin and retains water to keep your tissues well lubricated. Firmness and elasticity are visibly improved with this OSEA Hyaluronic Sea Serum, which strengthens your skin’s moisture barrier.

Use this facial serum for long-lasting hydration

Add OSEA Hyaluronic Sea Serum to your daily skin routine, especially if you live in cold or dry climates. Be sure to moisten your skin first, or else it may actually have the opposite effect. Apply a small amount to clean, damp skin on your face, neck, and decollete, then seal in all that hydration with a moisturizer. Just 2–4 drops should be enough.

How to Use
