The Pro System is Exponent's precision-dosing skincare system, designed for building a multi-serum routine in one streamlined format. It includes an Activated Serum with 45 doses of Active Ingredient Powder and a Hyaluronic Acid Hydrator Base with 90 doses, allowing you to run up to five different serums from a single base.

Each serum in the Pro System combines a concentrated Active Ingredient Powder with the shared Hyaluronic Acid Hydrator Base. You activate each dose at the moment of use, preserving full potency until it reaches your skin. The precision dispenser ensures consistent dosing every time.

Add-Ons are additional Active Ingredient Powders designed to expand your Pro System routine. Each Add-On includes 45 doses of a single active and a precision dispenser, and uses your existing Hyaluronic Acid Hydrator Base—no need to purchase a new base. You can add up to four additional serums to your routine this way.

The Pro System starts at $218 and includes one Active Ingredient Powder and the Hyaluronic Acid Hydrator Base. Each Add-On is $128 and covers an additional active powder that integrates into the same base, making it the most cost-effective way to run multiple actives in your routine.

All Exponent Power Serums are available as Pro System Add-Ons: Brightening Boost Vitamin C, Time Rewind Retinol, Calm Revival Green Tea Resveratrol, Firming Filter CoQ10, and Clear Comeback Probiotic Enzyme. You can mix and match based on your skin goals and build a routine of up to five actives, all activated from the same Hyaluronic Acid base.

Yes. The Pro System delivers better value even as a single-serum routine, with more doses and a larger Hyaluronic Acid Hydrator Base than a standard Power Serum. And when you are ready to add a second or third active, your Add-Ons slot right in without needing a new base.
