Cucumber mask. Put a cucumber, 1/4 cup of lemon juice, 5 teaspoons of honey, and 5 teaspoons of milk into a blender. Blend until well mixed. Pour mixture into a bowl. Stir in flour until the mixture gets a thick consistency. Refrigerate for 6 hours. Apply to your face once daily after you shower. You should leave it on for 15-20 minutes, and wash it off with warm water and a clean towel.
