You definitely need to use a moisturizer with this product. As for whether you should use moisturizer before or after this product - at first, to get your skin used to the retinol, it's a good idea to wear moisturizer underneath, to act as a buffer between your skin and the retinol. Yes, it reduces the effectiveness of the retinol. That's the point in the beginning - to protect your skin. But after a few applications like this (and only every other day, at first), you can be the judge of how your skin is reacting. After one month of use, I've learned that I can use it under moisturizer, every day for a few days, but then I ought to take a day off. Too much cell turnover too quickly and you'll either get a burn or just flaky skin. So, just ease your skin into it. And remember to wear sunscreen during the day even if you only use it at night.

It's is a 2 in 1 product: Retinol + night cream. You should not need a moisturizer over it. I have normal to dry skin and don't need one. Hope that helps.
