Toner is great for tightening the pores. Especially Witch-Hazel!
I did the toothpaste thing on blemishes, and it left a huge dry patch of bumpy, scaly skin in between my eyebrows =(.
Tea-tree is great for spotting on pimples.
Stingose is not. (I would have to be the only person stupid enough to put Stingose on a pimple. People, do not do this!)
Also, steaming your face is pretty good. Just fill up a basin with hot water, (maybe with some essential oils in it, I used tea-tree before I couldn't handle the smell any longer), put your face above the basin where the steam is, and whack a towel over your head to prevent steam escaping. Make sure you can breathe.
Ummm. trying to think of anything I may have forgotten...
Try to refrain from wearing lots of make up? And keep your hair clean, especially if it's on your face alot.
Honey masks are good for smoothing the skin.
Can't think of anything else at the moment.
