A Pro System refill is a fresh load of Active Powder or Quadruple Hyaluronic Acid Hydrator that reloads the Pro System Base and Precision Dispenser you already own. You keep your existing dispenser and replace only the formula inside, rather than repurchasing the full system.

Yes. Refills are designed to reload a Pro System Base and Dispenser you've previously purchased. If you're new to Exponent, start with the Pro System itself. If you want to add a new active powder to your routine, choose an Add-On instead of a refill.

Exponent Beauty Refills are designed to replace the Active Powder or Hydrator in a system you already own, allowing you to reuse your original Pro System Base and Precision Dispenser. If you want to introduce a brand-new serum or active ingredient to your skincare routine, you should purchase an "Add-On" rather than a refill, as it includes the powder dosing Globe + Dispenser component for that specific active powder.

Each Exponent Pro System Active Powder and Hydrator Refill is precisely measured to provide approximately 60 individual, freshly mixed doses, which generally translates to a 2-month supply depending on your daily routine frequency.

Each refill loads into your refillable Precision Dispenser and Base. The Quadruple Hyaluronic Acid Hydrator activates the Active Powders and boosts hydration, so your formula is freshly combined as part of your routine.

Our Quadruple Hyaluronic Acid Hydrator is uniquely formulated with four molecular weights of hyaluronic acid to maximize hydration and engineered to activate our Pure Antioxidant Powders. However, it is a great Hyaluronic Acid Serum on its own and can be slotted into any skincare routine. 

Clinical testing shows visible, clinical results in 1–2 weeks.

Pro System refills carry more of our active powders (on average, 4 g of Active Powder and 45 mL of Hydrator). Always match the refill to the dispenser you own.

Refilling reuses your existing Precision Dispenser instead of replacing the whole unit, which reduces plastic packaging. Exponent is a certified B Corporation.

To keep environmental packaging waste to a minimum.

Yes. Sustainability is core to our design. Our Active Powder and Hydrator refill jars are made from glass, the only infinitely recyclable material. By utilizing our refill collection, you keep your heavy-duty Pro System Base and Dispenser out of landfills indefinitely.
