I am new to SN over the last couple of weeks and I have already placed 3 orders. Does someone know where to sign up for the 12 step program?

I love the skin care, but am not sure about applying the serums. I have my sample of the Vitamin C peptide and the full size of the green tea & aloe. If I layer them do I need to make sure the first layer is dry before applying the second layer? Can they be mixed together?
I tend to use the GT & A at night since I use the BHA toner every other night. In the morning I love the way the Vitamin C makes my skin glow, but I feel like I need a little extra moisture because I will get oily otherwise. So far the Hemp moisturizer is working well and I have a sample of the Raspberry that I still need to try.
Thanks for your help!
