I like to stick a Q-tip into my foundation and dot my skin with it. Then I spread the foundation around with a plain, makeup sponge and/or a foundation brush. I've tried a Beauty Blender once and I didn't like it.
I really don't like and do not use beauty blenders, they clog the foundation into the pores, form dry particles, in a word, they are definitely not for dry skin.
I use brushes - flat and synthetic and then just make final aссent with my fingers.
