Wet face (or anywhere on the body), apply a couple of tablespoons of sea salt, then GENTLY massage with a wet washcloth or fingers.
Focus on the T-zone and cheeks, but avoid the eye area. After one or two minutes, rinse with cold water to tighten the pores.
It is important to do this regularly, or face-creams will not penetrate.
You can do this maximum once per week.
