Twitter and so if you follow me then you know that I don't recommend it. Maybe I'm biased (I am a licensed esthetician), but the fact of the matter is that products within a skincare line are really formulated to work with one another. Now, I do know that not every product within a line will work for you- and if that's the case, I do feel it's fine to substitute in another brand. But, I do stand firm on using a full regimen from the same brand.
So my question for you today is: Do you mix and match skincare brands?
