Thank you for your question. The Obagi Vitamin C Serum works well with the Nuderm system. After cleansing and toning with the Nuderm products, apply 3 to 5 drops of the Obagi Vitamin C Serum in the AM to the face and neck. Let the product absorb for about 3 minutes before continuing with the Clear (step 3) product. The Obagi Vitamin C Serum is a great antioxidant but will also give some hydration to the skin while going through the Nuderm program. Good Luck!
Yes. The C serum is a wonderful product with a powerful antioxidant. It compliments the nuderm system.
