You can use lemon as an effective toner to help reduce oil and prevent shine on your face. Lemon juice has astringent and antiseptic properties that clear up excess perspiration and eliminate unwanted shine caused by high humidity. What a simple solution, especially when of the most recent and suddenly indispensable products we're seeing in ads and on the shelves are the shine-stoppers, promising to provide all-day protection and a soft, matte glow just like the ones in the airbrushed magazine photos. But do we really need all those prepackaged cosmetics?

Consumer Affairs reports that Americans spend billions each year on cosmetics despite the fact that industry safety regulations fall woefully short of what groups like Campaign for Safe Cosmetics believe are minimally needed.

Some people are lucky enough to have skin that thrives on water and nothing else. Those are the same people that could swear off cosmetics without much of a problem. But for those who struggle with skin imbalances and blemishes, a few tricks and a little know-how can really reduce the number of packaged potions and powders that seem necessary.

One of the most liberating and empowering green things we can do is to adopt a few simple, homemade, DIY methods of caring for our skin.

Here, in honor of the shine-stopping craze, is a one-ingredient recipe for a fast, simple lemon shine control.

- Before bed, apply straight, fresh lemon juice to your face with a clean makeup brush. Leave the juice on your skin for five minutes. Rinse. Temporary redness, caused by the citric acid, is normal.

- For a morning toner, combine 10 drops of lemon juice with one half cup of water. Saturate a cotton ball with mixture and dab over clean skin. Do not rinse.
