The texture dries cleanly, leaving skin soft and subtly radiant without heaviness or stickiness. This fragrance-free formula is crafted for real skin, making a refreshing addition to daily routines and makeup-friendly days.

What makes this serum stand out

• Algae11 hydration blend: 11 marine algae work together to hydrate, soothe, and support elasticity. It helps draw moisture from the sea to maintain a hydrated appearance.
• Barrier-support duo: Niacinamide paired with Arginine helps strengthen the skin barrier, aiding moisture retention and calming visible redness for a more even look.
• Breathable, non-comedogenic formula: Water-based and light, it hydrates without clogging pores, making it suitable under makeup or SPF.
• Fragrance-free and skin-friendly: Free from fragrance, parabens, and drying alcohols, it aims to be gentle on sensitive or reactive skin.

How to use for best results

• Apply a few drops to clean skin after cleansing, morning and night.
• Allow it to absorb fully, then layer with your regular moisturizer or sunscreen.
• Because of its lightweight texture, it blends easily under foundation or tint products.

Real-life benefits you might notice
