Before you buy a body skin tightening cream, take a moment to read this article. Most of the lotions on the market are primarily composed of mineral oil, which won't help you tighten up saggy skin.

Some women love mineral oil, which is what we sometimes refer to as baby oil. They credit it with helping them to avoid stretch marks during pregnancy. They often use it after every shower. What the women don't know is that mineral oil serves only one purpose.

It forms a greasy layer that helps to keep the water from the shower in the skin's layers. "Oil and water don't mix." It repels water.

The problem with that is that it serves to clog the pores. Perspiration cannot be released through the greasy layer. So, toxins build up and blemishes are a common result.

Mineral oil does not improve the skin's moisture content, because it is not similar to the oils produced by the skin's sebaceous glands. We usually refer to the oils as sebum.

There are some plant-based oils that are nearly identical to the skin's sebum. The best body skin tightening cream contains a number of them. I'll tell you what the ingredients are, but you can expect to pay more for a product that contains them. The main reason that cosmetic companies use mineral oil is because it is so cheap. Not, because it is good for the skin's health.

Jojoba oil is one of the ingredients to look for. It is effective for reducing wrinkles and stretch marks. It can be used by all skin types, because it does not clog the pores, cause blemishes or allergic reactions. It is also rich in vitamin E, which helps to prevent and repair free radical damage, one of the causes of aging.

Body skin tightening cream should contain olive oil or an emulsion derived from it. It shows the closest compatibility to human sebum and helps to tighten the skin's layers by improving their moisture content. As the skin's cells become plump with moisture, you see a gradual improvement in firmness.

Grape seed oil is another ingredient to look for. Some of the best creams contain all three of these plant oils, because they work in "synergy". In other words, they complement each other, increasing the benefits more than any single ingredient, alone.

The best body skin tightening cream will contain one more ingredient. It has been named Functional Keratin by the company that created it. In clinical trials, creams containing it have been shown to improve the skin's firmness and elasticity by 40% in less than three weeks. It works by stimulating the production of collagen and elastin fibers.

Those fibers are primarily responsible for the skin's elasticity. The production of new ones slows down with age, which is why we start to see sagging. Luckily, it works for people that have lost a lot of weight or are trying to get rid of stretch marks.

You don't have to pay hundreds of dollars per ounce for body skin tightening cream. You will need to pay more than the drugstore varieties cost, but it's worth the cost to see the results.
