1. Real Lemon Juice
Whitening yellow nails is just one more thing you can do with the juice of a lemon, in addition to making lemonade and using it in baking.
Squeeze the juice from a fresh lemon into a small, shallow bowl. You can also use reconstituted lemon juice – just don’t use bottled lemon juice that has added sugar or contains any artificial flavors, sweeteners, or chemicals. Spend a few minutes letting your nails soak in the bowl of lemon juice. Repeat whenever needed.
After soaking, wash your hands and apply a moisturizing lotion.
