How do I use Active Hydration Serum with my Regimen?

R+F Active Hydration Serum works best when layered under a moisturizer or other skincare product. Apply it after cleansing and toning. Immediately follow with the next step in your skincare routine (Step 3 for REDEFINE, REVERSE and UNBLEMISH and Step 2 for SOOTHE); do not wait for product to dry.
