In the small bowl mix water and the green tea powder.
Stir with a fan like cosmetic brush, the consistency should be runny but not watery; if watery add more green tea powder vice versa if opposite.
Apply the mask on to a well washed and clean face with the brush until your face is a nice shade of dark green.
Let dry and be patient don't poke your face every 2 minutes the green tea stains! and don't talk or smile the mask will crack
Wash when mask is nice and dry (almost crusty)make sure no trace of green is left behind.
