I use all Lush skincare, and I LOVE it. I have combination skin with occasional breakouts (usually stress or PMS related) and a bit of dryness in the winter, and with Lush, my skin has never looked better. That said, I know from browsing the Lush forums that some people do better with it than others. It's true that Lush is not totally organic, but I think if you want to get away from a lot of nasty chemicals, it's a good line.
For reference, here's what I use:
AM: Aquamarina cleansing roll (smells funny but is a nice, calming cleanser), Tea Tree Oil (all around nice toner for oilier skins), and Imperialis moisutrizer (fairly light with a slight mattification effect on oilier skins)
PM: Alternate between Herbalism (another funny smelling one, but really cleansing with nice exfoliating bits) and Coalface (which gives a great fresh feeling clean) for cleansing, Tea Tree Water, and Celestial moisturizer (too greasy for daytime, but a nice drink when my skin is feeling dry).
Occasionally: Ocean Salt (for awesome skin smoothing, blackhead fighting goodness) or Mask of Magnaminty (deep pore cleansing mask that smells like mint chocolate chip ice cream).
Some words of warning about Lush: All but two of their moisturizers contain cocoa butter, and not all skin types can get away with this without breaking out. Also, if you're going to switch to Lush entirely, do it one product at a time so as not to freak your skin out. If you live near a Lush store, go in and ask for samples of skincare; they are usually very generous. They have a bunch of different products but not everyone has good luck with them, so if you can, try before you buy so you don't waste a lot of money before finding out that your skin hates Lush!
