I do get asked for directions on how to use the different products, which order and when they should be used, so I thought I would share the content of an email I sent a customer about this when she asked.
A good rule of thumb is that the thinner (runnier) products should go on first followed by thicker (more solid products) - ie. go from thin to thick. Things like oils sink into the skin to deliver nutrients where they're needed, while thicker products like lotions or moisturizers include waxes that are designed to form an "occlusive layer" which just means that they hold moisture in and protect the skin by sitting on top of the skin.
Anyway - here are the instructions I sent her which I hope are useful. Let me know any questions! claire@bellavirtu.com
