Watermelon seed paste for Skin
Make paste of watermelon seeds. Add some lemon juice and some crystals of alum. Apply to your skin, leave for 10-15 minutes and wash off the paste from skin. It is also rich in anti-oxidant flavonoids like lycopene, beta-carotene, lutein, zeaxanthin and cryptoxanthin. These antioxidants are found to offer protection against colon, prostate, breast, endometrial, lung, and pancreatic cancers.
