You should NOT let a clay mask dry completely on your face. When you let a clay mask dry all the way, you can cause negative side effects. The “wet” phase of a face mask is when your skin soaks up all the good stuff. When it starts to dry, the mask “stimulates blood flow” as it gets tighter on your skin. But if you let it get too dry, it starts sucking up natural oils, and that’s not ideal!
A few tips when using a clay mask:
Wash your face before you use a clay mask. It’s not a face wash, and you don’t want to end up sealing in any nasties from your makeup. Exfoliating is a good idea before using a mask. When you’re finished and you've washed your face clean, make sure you moisturise and replenish any natural oils that have been soaked up by the clay. You only need a thin layer to utilise the mask’s purifying qualities.
Now you know how to properly use a clay face mask!
