Mineral oil is used in many skin care products, including some advertised as the "best face cream". It's good at removing makeup, but it also can be used as brake fluid in your car because it's a byproduct of petroleum, the stuff that's left over when crude oil is turned into gasoline.

Still want to use it on your face?

Then there's "organic." If that word is on the label, we are assured what's inside is made with all-natural ingredients and no chemicals have been added. That's fine if it's something basic, like milk or juice. But when it comes to skin care, you want ingredients that, in addition to being organic, also are proven to give great results.

You also want the good stuff in the right quantities, blended with other all-natural ingredients that work together in harmony. Remember, this is your face we're talking about.

What you look for in a face cream will depend, in part, on your age and skin type. Though the goal is always the same-to keep your skin soft with a youthful glow. You can be 20 years old and have great natural skin, but if you spend a lot of time at the beach soaking up those UV rays, you're going to need just as much help as your grandma to make you look and feel your best.

When science and nature work together, it can be a beautiful thing. The most effective face creams stimulate the production of collagen and elastin, the building blocks of the skin that help give you that youthful glow. Look for a product that contains antioxidants, which not only help produce more collagen, but also lead the fight against the elements like sun, wind, and pollution.

There's a lot to think about it. Fortunately, the companies that produce the best face cream have done a lot of work for you.
