I was blessed with good skin, although I had acne like any teenager. These days, I mostly use stuff from Lush cosmetics, and even then mostly because I like going in there, since it's like a candy store (all the soaps and stuff are these bright colors and swirls and stuff, and they sell all sorts of wacky bubble-bath bars and the likes.)
A female friend who has a tough time with her complexion got me hooked on Lush's "Coal Face" soap; it's black and it smells kind of like a petroleum product, but somehow I've grown to love the smell, probably because it works so damned well. Got a couple straight friends hooked on it, too, a guy and girl, who each buy a bar any time they're in a city with a Lush.
I also use the Lush "Olive Branch" body wash, mostly because I absolutely love the smell. Masculine, but with bergamot and olive leaves, it's hard to describe, but really distinct and I'm totally hooked.
Then I use the Lush shampoo bars, because they're like $9 and last me at least 2 months each, so it's cheaper even than the cheapest brand of liquid shampoo from Walgreens, and it takes up less space.
On a whim I bought a jar of Lush's "Ocean Salt" exfoliating scrub, which is citrus stuff (grapefruit, lime, etc.) and coarse sea salt. I don't use it often (because it is *coarse*) but every so often if my face is dry or whatever, I'll use it and it feels great and leaves my skin looking revived.
The only skin problem I haven't quite figured out how to solve yet is, well, mildly embarassing -- when I am cycling a lot, especially long distance rides, I get blemishes on my backside, where the pad and elastic waist are in the cycling shorts. I use the oh-so-delicately-named Chamois Butt'r, i.e. greasy lotion you spread on the shorts and your ass, and that goes a long way towards preventing chafing, but just the pressure against the shorts, the sweat, areas where it doesn't wick & breathe, it all takes its toll. I have yet to find a great solution to that, since lotions and whatnot don't seem to help much, and I can't use an exfoliant nor astringent right after a long ride or I think I would just be screaming in agony. Plus, it's kind of hard to exfoliate your own ass.
