different ppl have different make up techniques, like Billy B, Sam Fine,Tricia Sawyer,and Elke Von Freudenberg. one thing I learnd from billy b is that he does not use concealer b/c its a waste of money and foundation works just fine, tricia sawyer taught me about make up brushes and cream bases, kimara anert taught me about foundation and how she apply's it. my mom was always a person having her makeup and hair done at prestigous salons and I would go with her at 10yrs old and they didn't have a problem teaching me or telling me their secrets, and yes learning different techniques is confusing but if you feel comfortable with applying foundation one way then do it, or applying eyeshadow the way someone else does it, fine it is all about feeling comfortable. that is why it is most confusing sometimes.
