Combine 1 tablespoon cocoa powder, 1 tablespoon sour cream, 1 tablespoon honey, and one egg white. Apply to face and let dry before rinsing. The powerful ingredients make this a multi-tasking wonder-cream: Sour cream is a form of lactic acid that hydrates as it gently exfoliates; honey is a humectant that also boosts hydration while the protein in the egg white tightens and firms skin.
