Blackheads - Fill your sink up with boiling hot water and hang your head infront of the sink (close to the water, hair tied back tightly) and stay there for as long as you can stand, then drain the water (tie string to the plug so as not to burn hands)
Then use an exfoliant on the face, and scrub thoroughly, then wash off with luke-warm water, then use cold water then pat dry. Don't scrub.
For spots - Apply toothpaste to the spot, and leave on for half an hour, letting it dry it out. Then wash off, dry, and apply T.C.P, no such thing as too much. Before bed, in the morning. No more spot!
(The steaming of the face opens the pours and softens you're skin and works a bloody well wonder!)
(T.C.P also softens lips, cures mouth ulcers, and spots.)
