What's your favorite DIY skincare recipe or mask using natural ingredients? What benefits does it offer and how often do you use it?

I love using a yogurt and oatmeal face mask for smooth, refreshed skin. I combine 2 tablespoons of plain yogurt with 1 tablespoon of ground oatmeal and a teaspoon of honey. The lactic acid in yogurt gently exfoliates, while oatmeal soothes and honey hydrates. I apply this mask once a week, and it leaves my skin soft, nourished, and radiant.
