Love using this product!
"I love using this product with the retinol powder. On days I am not using retinol, I will use this serum on its own. It is so lightweight and applies easily."

Suitable for
All skin types, including dry, mature, blemish-prone, combination, and sensitive skin.
Why we stand behind it
Normally, antioxidants degrade and oxidize when coming into contact with light, air, or water but these clinical-grade Power Serums are activated fresh for peak potency.
Powderized ingredients are precisely dosed with a patented, precision dispenser and seamlessly activated in your palm with a hyper-moisturizing Hyaluronic Acid. The result? A serum that delivers visible results in 1-2 weeks without irritation.
Multi-weight Hyaluronic maximizes moisture-binding capacity—working on multiple layers of skin for supreme absorption of concentrated actives.
Note: this is a Hyaluronic Acid Refill, intended to be used with any existing Exponent Power Serum.
Key ingredients
Hyaluronic Acid: this multi-weight formula penetrates multiple layers of skin to deeply hydrate, boost elasticity, plump and restore the skin from within, helping to smooth fine lines and wrinkles.
