I pretty much do same as what I would do on the face, I see more gals who just don't ever exfoliate the back, and a few with acne. If it's mainly dead skin buildup I will use a good exfoliateing scrub-like salt/sugar etc., with acne, I will use either a 1-2 layer peel or emzyme peel followed by extractions.
A forward contract is an agreement between two parties to buy or sell an asset at an agreed future point in time. The trade date and delivery date are separated. A futures contract is a standardized forward contract that is traded on an exchange, like SAFEX. Other than forward contracts, futures contracts are not linked with specific buyers.
Because it is a function of an underlying asset, a futures contract is a derivative product. Contracts are negotiated at futures exchanges, which act as a marketplace between buyer and seller. The buyer of the contract is said to be  long , and the party selling the contract is said to be  short .
