The first thing that any professional makeup artist will tell you about application is to start with a clear, blank canvas.
We’re not saying there won’t be times that we’ll lazily apply a second base layer without removing the previous but if you’ve ever done this, you’ll immediately notice that it just doesn’t sit as well. That’s why your skincare routine should be considered in equal importance, from cleansing to the exfoliation (be it chemical or physical). The same is true for lips.
