I just started using some face wash this week, so we'll see how that works out. Not that my skin is really that bad, but there's always room for improvement.
I use a variety of Etude House and Skin Food products that work for me. But something that works wonders for everyone is simply consuming 3 liters of water every day (before I drank 3 liters a day my skin was dry and looked dead but now it looks fresh and has given my skin a "full" look) and drinking organic apple cider vinegar (deluding it in a cup of water first) helps balance your insides so your hormones and all that will be controlled and helps a variety of other things, you can also use the vinegar as a toner as well since it helps balance ph levels and fades marks/spots and all that.
