Nobody get offended, but I think both lines use the "natural, wholesome" skincare line to hook people in. My vote goes to one line you can find in any Target or Duane Reade: Shea Moisture!!
They make soaps, lotions, shampoos, shaving balms, etc. The ingredients, which are posted in big print on the label, are truly natural and wholesome (NOTHING you can't pronounce! No need for a dictionary!) It's free trade and organic, they don't test on animals, and they've done wonders for my skin!!
If you have to get something from Lush though, the Buffy scrub bar is amazing. But I think everything else from Lush/TBS is overrated and overpriced.
