<bot>: You can use natural ingredients such as honey, avocado, turmeric, yogurt, lemon juice, and oatmeal to make face masks. To make one of these masks, simply mix the ingredients together in a bowl and apply it to your face. Leave the mask on for 15-20 minutes and rinse it off with warm water. For maximum efficacy, repeat this process two to three times a week.
