Combine all of the ingredients in a small non-metal dish and slowly add warm water until the consistency is smooth and spreadable. Depending on the brand and thickness of your yogurt, the amount of water needed may vary.
Apply to your face and neck, avoiding the eye area. Leave on for 10-15 minutes before rinsing with warm water.
Notes
In general, bentonite clay works well for most skin types. If your skin is super sensitive, stick with a gentle clay like white kaolin or French green.
