When life gives you lemons, you can do a lot more with them than make lemonade. Lemon can help exfoliate your skin, it can act as a skin bleach because of its acidic properties, and it can even help erase wrinkles because it acts as an astringent. Other people use it to soften the skin. You can rub lemon on your skin in a variety of ways to use it as a beauty aid or skin treatment.

Lighten dark elbows with a lemon. Cut a lemon in half, then rub each lemon half on one elbow, as if you were juicing the lemon with your elbow. This will cleanse your skin and, when done daily, will lighten your elbows over time.

Tone your skin with lemon and water. Dilute lemon juice with water, then apply to your skin with a sponge, taking care to avoid the eyes.

Remove freckles using lemon and egg whites. Mix one egg white with 1/2 tablespoon of lemon juice, and apply to the affected areas. Wash it off in 20 minutes and repeat twice a week until you have achieved the desired results.

Exfoliate rough spots on your skin with a lemon peel. Rub your elbows, knees and other patches with a lemon peel to work out the dead skin.

Treat blackheads and other blemishes with lemon juice. Dab lemon juice on the affected area in the evening, then wash it off in the morning.
