Frequently Asked Questions

What is the difference between Cosmedix Define and Refine?

Define contains a 2% AGP Retinol Complex and a triple AHA, formulated as an all-in-one treatment cream for retinol beginners and all skin types. Refine contains a 4% AGP Complex with 0.5% Retinol as a dedicated serum, formulated specifically for oily, combination, and blemish-prone skin as a step up in retinol strength for those who have already built tolerance. Cosmedix positions Define as the first step and Refine as the next level.
How often should I use Refine?

Cosmedix recommends starting with every 1 to 3 nights and working up to nightly use as your skin builds tolerance. Begin by applying every third night and gradually increase frequency as your skin adapts. It is a PM-only product.
Is Refine suitable for all skin types?

Refine is formulated specifically for oily, combination, and blemish-prone skin. It is not recommended as a first retinol product - Cosmedix advises starting with Define 2% to build tolerance before stepping up. It is also not suitable for use during pregnancy or breastfeeding.
