I use garlic too, almost every day. It's a real winner. You know the ancient Egyptians used it as well. They found a clove of garlic (somewhat dried up by then) in Tutankhamen's tomb. It's also a powerful aphrodisiac.
I agree with the sugar. Especially the processed stuff. It has an effect on the pores of the skin causing them to contract / close up. Which leads to blockages then pimples.
