Zero-cost home care for a student living alone! I'm challenging myself to brighten my complexion with rice water facial cleansing.

I've been cooking at home lately to save money on food, so I've been trying to use the water left over from rinsing rice for my face wash instead of throwing it away. It's been about a week, and I can definitely feel like my skin texture has gotten smoother. It feels great to find a way to look pretty without spending a lot of money haha. Do you all have any small home care tips?
