The tea is pretty inexpensive -- about $5-$6 for a tin at the local Korean market. Here are a couple of recipes for a simple cleanser, scrub, and mask:
Job's Tears Cleanser
Dissolve one teaspoon of Job's Tear's Powder in 1/2 cup warm milk. Gently wash face. The lactic acid in the milk acts as a gentle exfoliator, removing dead skin cells and leaving your face baby soft.
Job's Tears Scrub & Mask
Don't forget to enjoy a cup of yulmoo cha afterwards!
