I'm a OSPW just starting out. I have a question about the nighttime routine. After cleansing, should I use the serum, then the retinol product, or the other way around?

So should I use the Olay Rregenerating Serum and then the Topix Replenix Retinol 3x or the the other way around?

And should I chose to try a moisturizer (I am closer to dry in the winter), where does that fit in?

I am adding one product at a time and giving it 3 days/times before I try a new one (I gave 36 hrs for cleanser because 2x per day). Does that sound about right?


Thanks!
Jen
