A lot of people mix on their
skin instead of in seperate bottles. It works just as well and is a lot less trouble. You also don't have to worry
as much about which base each product has. You don't have to worry about emulsions and such things to avoid
seperation.
But you would be well off to get familiar with each of the products before you mix them. Otherwise,
you have no way of knowing what result came from which product.
