I've been using this home made face mask everyday for the past 1 week and it has helped even my skin tone and lighten dark circles.
Half a medium potato
1 tablespoon rice flour
i tablespoon milk
Grate the potato and squeeze out the juice. Mix it with milk and flour. Add more flour if you want a creamy consistency that will stay on the face or use a face mask sheet to soak up the mixture. Apply to face and wait for 20 minutes before washing off with lukewarm water. Apply moisturizer immediately.
I know a lot of people uses lemon juice for bleaching but the downside it that it causes sun sensitivity. The potato mask is a good alternative.
