Skin's own moisture-binding molecules become less abundant with time, so skin tends to hold onto hydration less reliably as the years pass. Hydra Catalyst is built around Hyaluronic Acid and Polyglutamic Acid at a combined 0.8% concentration, two actives that approach hydration from different angles but work together. Hyaluronic Acid helps draw moisture to the skin, while Polyglutamic Acid works alongside it to help hold that moisture in place, supporting a more consistently hydrated look with continued use.

Who This Is For

Formulated for all skin types (including sensitive). And especially skin that feels tight or loses hydration through the day.

Ingredients

Aqua (Water), Glycerin, Aloe Barbadensis (Aloe Vera) Leaf Juice Powder, Cucumis Sativus (Cucumber) Fruit Extract, Tocopherol (Vitamin E), Phenoxyethanol, Sodium Hyaluronate (Hyaluronic Acid), Carbomer, Polyglutamic Acid, Ethylhexylglycerin, Sodium Hydroxide

Ingredient Breakdown

Aqua (Water) The primary solvent in the formula, used to dissolve water-soluble ingredients and provide the base for the gel serum texture.

Glycerin A humectant that draws moisture into the outer layers of the skin, helping to keep the skin hydrated throughout the day.

Aloe Barbadensis (Aloe Vera) Leaf Juice Powder Derived from the leaves of the Aloe Vera plant, this ingredient is known for its soothing and hydrating properties. It helps to calm and condition the skin while contributing additional moisture to the formula.

Cucumis Sativus (Cucumber) Fruit Extract A soothing, non-irritating plant extract known for its calming and emollient properties. It contains amino acids and organic acids that help maintain the skin's natural acid balance, as well as compounds with soothing properties.

Tocopherol (Vitamin E) A naturally derived antioxidant that helps protect the skin from environmental stressors. It also conditions and nourishes the skin and helps to keep the formula stable over time.

Phenoxyethanol
A safe, gentle preservative that has been used in cosmetics since around 1950. It maintains the safety and stability of the formula and is approved for use up to 1% globally.

Sodium Hyaluronate (Hyaluronic Acid)
The sodium salt form of Hyaluronic Acid, a naturally occurring molecule in the skin with exceptional water-binding capacity. It helps the skin to retain moisture, contributing to a plump, well-hydrated complexion.

Carbomer
A polymer used to help thicken and stabilise the formula, contributing to its smooth gel texture.

Polyglutamic Acid
A fermentation-derived ingredient with exceptional moisture-binding capacity, capable of holding significantly more water than Hyaluronic Acid. It forms a light, hydrating film on the skin's surface that helps to lock in moisture and support a plump, smooth complexion.

Ethylhexylglycerin
A skin-conditioning agent that works alongside Phenoxyethanol to maintain the formula's preservation system, while also contributing a pleasant feel on the skin.

Sodium Hydroxide
A pH-adjusting ingredient used in small amounts to help set the formula's pH to the correct level.

How To Use

Apply 1 to 2 pumps to freshly cleansed, damp skin, pressing gently into the face and neck. Allow to absorb before following with a Catalyst serum or hydrator.

When using alongside active serums, apply Hydra Catalyst first to create a hydration buffer between the skin and the active ingredients.

How It Works

With consistent use, skin looks plumper, feels softer and feels hydrated through the day and night. Hyaluronic Acid helps draw moisture into the skin and helps hold it there, a well-researched mechanism skin relies on naturally, though less reliably as the years progress.

Polyglutamic Acid works at the surface to help slow how quickly that moisture escapes, adding a second layer of support alongside Hyaluronic Acid so hydration is approached from two different angles.

Applied before a Catalyst serum or any other active, the formula helps create a hydration buffer that supports skin comfort through stronger actives. Retinoids in particular ask a lot of the skin barrier, and well-hydrated skin handles that better.

Hero Ingredients

  • Hyaluronic Acid

    Draws water to the skin and binds it there, addressing the drier appearance skin can take on over time.

  • Polyglutamic Acid

    Works at the surface to slow moisture loss and, with consistent use, helps protect the hydration your skin naturally holds.

  • Aloe Vera

    A soothing botanical that keeps the skin calm and settled, particularly for those using active ingredients.
