Cholesterol
You know that waxy stuff that is responsible for the early heart attacks and is present in basically anything that tastes good? Well it’s also a pretty popular ingredient in many moisturizers and face creams. In fact, as well as being found in cheese milk, beef, pork and other delicious items, cholesterol is found on our own skin. It’s a necessary component on the top layer of skin that helps to keep the skin moist and protect the lower layers. As it helps the skin to condition, it’s a popular ingredient in moisturisers and those anti-wrinkle face creams. Surprisingly it’s usually listed under its real name, which just goes to show what we’ll rub on our faces to stay young.
