Best Moisturizer For Dry Skin

I'm convinced the best moisturizer for very dry skin is one of a few oils whose benefits have been proven for centuries -- natural and vegetable-based, like so many great skin care products.
The best moisturizer oil must be absorbed quickly by the skin -- it shouldn't just lie on top, a greasy coating. I'm thinking of two especially, natural oils that are non pore clogging (unlike petroleum products). They are avocado oil and macadamia oil, both amazing natural moisturizers and lubricants for the skin.
Avocados have been valued for centuries -- as a lot more than just a versatile, healthy food. Avocado oil is famous for its healing and moisturizing properties. Some of the reasons have just become understood to scientists in recent years: avocado oil is rich in vitamins A, D and E, beta carotene, potassium, even lecithin.
Avocado oil has many skin benefits, beyond being a contender for the best moisturizer oil. A study done in Israel found that avocado oil significantly increased collagen in the skin. Collagen is one of the most important skin proteins; with elastin, it makes the skin strong and flexible. We tend to lose collagen and elastin as we get older, a major contributor to very dry skin.
Avocado is also high in sterolins, natural vegetable compounds which have been shown to soften and moisturize skin, even to reduce age spots.
Another oil that could claim to be the best moisturizer for very dry skin is macadamia oil (also called macadamia nut oil -- macadamia nuts are the source of this wonderful oil).
Macadamia oil replenishes lost oils in the skin that lead to chapping, cracking and inflammation. Like avocado oil, macadamia oil complements our natural skin oils very well; it won't strip our skin of our own natural oils, which petroleum-based products will. One scientific explanation for these benefits is the effects of palmitoleic acid, one of the molecules that make up macadamia oil.
These superb natural oils have been proven for many years to be among the best moisturizers for very dry skin. I firmly believe in combining proven, natural ingredients with cutting-edge therapies for the best moisturizer. Here are some other ingredients that complement these natural oils in the moisturizer I use myself.
