So I am pretty savvy on skincare, and I want to switch to Lush's line of products since everything else they make is perfection. Even so, I don't know exactly which products I should use, as I don't know the products well enough and they all sound so incredible that I can't decide. Since my skin is both quite oily and acne-prone, I need a fairly gentle cleanser to absorb the excess oils, and a moisturizer that will put back the right amount of oil. I'm not too particular about the scent, also.

Herbalism is a great cleanser for oily, acne prone skin.  I had my sister use it when she went off her birth control (her skin went NUTS) and it helped bring everything back to normal.  I’d also check out Tea Tree toner water for after you cleanse and Vanishing Cream moisturizer, which is nice and light and has lavender to heal breakouts and balance the sebum production in your skin.  You could also try Cupcake face mask which is great at sopping up oil and pulling out the crud in your pores ^^
