This highly concentrated serum features 3% low-molecular-weight hyaluronic acid to deliver deep, long-lasting hydration where your skin needs it most. Designed to improve moisture retention and skin elasticity, it absorbs quickly with a smooth, non-greasy finish, helping to plump the skin and reduce signs of dryness.

Enriched with Natural Moisturising Factors (NMF) and ceramides, the formula not only replenishes moisture but also strengthens the skin’s protective barrier. Ideal for dry, flaky, or rough skin, this serum restores a healthy glow while smoothing texture and enhancing comfort—even under makeup.

Key Benefits

  • 3% Low-Molecular Hyaluronic Acid
    Delivers hydration deep into the skin to plump and soften from within.

  • Strengthens Moisture Barrier
    NMF (amino acid complex) helps restore barrier resilience and prevent moisture loss.

  • Non-Greasy, Fast-Absorbing Formula
    Leaves skin smooth, supple, and prepped for layering.

Key Ingredients

  • Hyaluronic Acid (3%) – Intensely hydrates and plumps the skin for improved elasticity and smoothness.

  • NMF (Amino Acid Complex) – Supports moisture barrier function and improves water retention.

  • Ceramide NP – Reinforces the skin barrier and helps lock in moisture.

How to use

Apply a few drops onto cleansed, damp skin. Gently pat to absorb. Use morning and evening, and follow with a moisturiser to seal in hydration.
