Elbow and knee bleacher:
If your elbows and knees appear dark, simply rub them with half of a lemon. It's like magic!

Blackhead treatment:
It may sound too good to be true, but because lemons are antibacterial, they can help treat acne. Just slice a lemon, and squeeze the juice on your face. Your blackheads will start to fade before you know it.

Teeth whitener:
Mix baking soda and lemon juice, and apply it to your teeth with a clean soft toothbrush to scrub your teeth and rinse.
Canker sore treatment:
Sturn also uses a few drops of the lemon essential oil on her canker sores to help them heal faster.

Skin brightener:
Lemons are rich in vitamin C and citric acid, so they can help brighten and lighten your skin when used over time.

Nail strengthener:
Have you been getting too many gel manicures? Make a mixture of your favorite cooking oil (try olive oil) with lemon juice, and soak your nails. This is a good practice if your nails are dry and brittle, but it's also a great way to help fix nails that have yellowed.

Hair Lightener:
Score dye-free DIY highlights with lemon juice. Apply it before you expose your hair to sunlight to score a sun-kissed color. The lemon juice can also help treat a dry scalp and dandruff, so apply it liberally.
