I genuinely love every Lush product I have ever tried but my favorite are the bath bombs and the shampoo bars. The shampoo bars really do lather just like liquid shampoo and are great for traveling with a carry-on because there's no liquid to worry about.
Oh man, there are too many to count! I love the Dragon's Egg bath bomb and Comforter Bubble Bar if I'm in need of some pampering. Grease Lightning is a lifesaver when it comes to combating breakouts and Angels on Bareskin is a beautiful cleanser!
