When your skin is thirsty, stressed, and reactive all at once, you need something that does several things without creating more problems. The Skin1004 Madagascar Centella Hyalu-Cica Blue Serum is exactly that — a lightweight gel serum that layers hydration and calm simultaneously, built around the brand's signature Hyalu-Cica approach.

The foundation here is 38% Centella Asiatica Leaf Water from Madagascar — not an extract buried at the bottom of the list, but the actual base of the formula. Centella's active compounds, madecassic acid and asiaticoside, do real work: they support the skin's natural hydration mechanisms, calm inflammation, and help fade redness over time.

Layered on top of that is a five-type hyaluronic acid system — Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, and Hydrolyzed Sodium Hyaluronate — that works across multiple skin depths to lock in moisture. Ceramide NP (delivered in nano-sized particles for deeper penetration) strengthens the barrier, while Niacinamide and Adenosine address brightness and the early signs of ageing. Polyglutamic Acid adds another layer of surface hydration, and Panthenol keeps things soothing.

The texture is a non-sticky, watery gel — it absorbs instantly and leaves no residue. The blue hue comes from Hydrolyzed Gardenia Florida Extract; the subtle melon and pear scent from the fruit extracts in the formula.

SKIN1004 is one of Sul Skin's most trusted cica-forward brands. The Hyalu-Cica range is a particular favourite for combination and sensitive skin types that need hydration without heaviness.
