Combine the clay, baking soda and citric acid in a small bowl and stir (for extra detox power, you can add the activated charcoal and matcha powder now too). Add the glycerin and honey. Stir again.
At the last minute, add the rosewater and stir quickly. It's going to start to fizz so you want to work fast!
Notes
To use, use your fingers to apply the mask to your face and neck. Let sit for 5 minutes then use a warm washcloth to gently massage the mask into skin. Rinse your face and pat dry.
