How to apply stick foundation and primer? I have oily and acne-prone skin and was recommended the Lancôme teint idole stick foundation and blur-and-go primer from the staff at Sephora. I’m having a hard time applying it well like the staff did. She used a Morphe brush and I’m using a moist drug store beauty blender that she was also good. Any tips on how to use this product properly without having the makeup separate as soon I try to blend it?
