They are all good except makeup but not all are worth spending your money on.
Paula is the queen of acid toners and her retinols and serums are very very good. If you have oily skin the 2% BHA is amazing.
However once you've bought those you might as well buy cheap moisturiser/SPF/cleanser/ I'm sure those are all good too it's just those will be overpriced for what they are - cleanser is on your face for seconds, if you have a great serum you don't need masses of anti-oxidants in everything else despite what Paula may think etc
