Coeternal Deep Moisture Serum — Hydrating Algae11 Serum with Niacinamide & Arginine, Fragrance-Free, 50ml

Deep hydration that feels weightless

Coeternal Deep Moisture Serum delivers a hydration surge from the first use. The lightweight, fast-absorbing texture sinks in without heaviness, helping skin feel softer and look radiant with a natural glass-skin glow. It’s gentle enough to wear under makeup or SPF, making it easy to fold into a daily routine.

What makes it different

At the heart of this serum is Algae11, a signature blend drawn from 11 marine algae known for their hydrating properties. This extract works with Niacinamide and Arginine to support barrier resilience and help lock in moisture. The water-based base keeps things breathable and non-comedogenic, so pores stay clear while you hydrate.

• Deep hydration from the first use with a non-sticky finish.
• Algae11 hydration extract draws moisture from the environment to support a plump feel.
• Niacinamide + Arginine provide potential barrier support and calm the appearance of redness.
• Lightweight, water-based texture that layers well with makeup and SPF.
• Fragrance-free formula designed for sensitive, reactive, or post-treatment skin.

Who may benefit

Those with dry or dehydrated skin may notice improved softness and a more even texture. The fragrance-free option is a thoughtful choice for anyone seeking minimal irritation, while the non-comedogenic profile helps keep pores clear during daily wear.

How to use

• Apply a few drops to clean skin morning and night.
• Gently press or massage upward to aid absorption.
• Follow with moisturizer or sunscreen to seal in hydration.

Tips for best results
