A Power Serum refill is a fresh Active Powder or Quadruple Hyaluronic Acid Hydrator that reloads your existing, patented Power Serum Precision Dispenser. You reuse the dispenser you already have and simply replace the formula inside.

Yes. Power Serum refills are designed for a Power Serum dispenser you've previously purchased. New to Exponent? Start with a Power Serum first, then refill it going forward.

 Refills are optimally dosed by the refillable, patented Precision Dispenser. The Quadruple Hyaluronic Acid Hydrator activates the Active Powders while maximizing hydration, keeping your routine freshly combined.

Each Exponent Power Serum Active Powder and Hydrator Refill is precisely measured to provide approximately 45 individual, freshly mixed doses, which generally translates to a 6-week supply depending on your daily routine frequency.

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 (about 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 eliminates plastic waste. 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 Power Serum Dispenser out of landfills indefinitely.
