THE LAB by BLANC DOUX Oligo Hyaluronic Acid Hydro Serum 50

A serum-essence with one straightforward promise: deliver water, deep down, without weighing skin down. The formula works with molecular size — low molecular weight sodium hyaluronate fragments that reach further into the skin than those found in a standard moisturiser. The result: skin that drinks without feeling sticky, that regains plumpness in a way you can feel but can't quite explain.

Texture and ingredients — Sodium hyaluronate is concentrated at 5,000 ppm, twice the level typically found in a first-step treatment — a difference you notice within the first few seconds of applying it. It's paired with AQUAXYL 1%, a complex made up of Xylitylglucoside, Xylitol and Anhydroxylitol derived from plant sugars, which works on the skin's natural water-circulation channels. Chondrus Crispus Extract (red algae) and Sparassis Crispa Extract (mushroom) round out the formula with film-forming polysaccharides that hold moisture at the surface. Panthenol and Allantoin support skin comfort, all without added fragrance. The light gel-water texture leaves no greasy film behind.

How to use it — A few drops in the palm of your hand, just enough to cover your face without overdoing it. Apply following the natural direction of your skin's texture, then gently pat with your fingertips until fully absorbed — pressing rather than dragging helps the formula sink in without pulling at the skin. It fits naturally into your routine after cleansing and before richer products: its water-based composition primes skin for everything that comes next.

• Low molecular weight Sodium Hyaluronate at 5,000 ppm: twice the concentration typically found in a classic toner, according to the supplier's data sheet.
• AQUAXYL 1% (Xylitylglucoside, Xylitol, Anhydroxylitol): a plant sugar-derived complex that opens up the skin's water-circulation channels.
• Chondrus Crispus Extract and Sparassis Crispa Extract: two plant-based sources of polysaccharides for a reservoir effect at the surface.
• 50 ml size: a standard volume for a daily serum, suited to morning and evening use over around 4 to 6 weeks.
• Fragrance-free, non-sticky gel-water texture: a good fit for sensitive skin that doesn't get on well with heavy or overly rich formulas.
