The Science of Goat Milk Soap
How Goat Milk Soap Benefits Your Skin
Once you try goat milk soap, it's hard to go back to anything else ever again! It's the goat milk that is the "not-so-secret ingredient" in our fabulous soaps! Oh, the wonders of fresh goat milk!
Goat milk is the KEY natural ingredient in all of our soaps here at Bend Soap Company. There is over 26% farm fresh goat milk in every bar of soap. So just what is all the fuss about? What is so amazing about goat milk?
Goat milk is easily absorbed by the skin. This is important. Your skin acts as a barrier to keep bad stuff out, which is great! In order for a substance to penetrate the skin, it must first make its way past the tightly packed layers of dead skin cells that cover the outside of the epidermis, or outermost layer of skin. These dead skin cells also contain glycolipids which effectively “waterproof” your skin- keeping “outside water” out and “inside water” in. Fats, however, are not repelled by the glycolipids. Since goat milk is comprised of medium chain fatty acids (such as capric, caprylic, and caproic acids) and short protein strands it can easily navigate this densely compacted maze of expired skin cells, penetrate the glycolipid “waterproof” barrier, and reach the layers of living tissue hidden beneath. Goat Milk’s aptitude for increased absorption allows for intense hydration of the skin and effective delivery of the fat-soluble vitamins A, D, E, and K to the living tissue hidden beneath this barrier. Contrast goat milk’s ability to naturally penetrate the skin with commercial water based detergents which rely on chemicals to bypass the skin's defenses and deliver synthetic vitamins to living tissue.
Goat milk naturally contains lactic acid which helps to remove dead skin cells by weakening the bonds between them. Imagine a handyman scraping the shingles off of a roof with a tear off shovel. The ugly, dead skin cells are removed leaving more youthful, supple skin in its place.
Random Fact: One of the main ingredients of dust is dead skin cells. In fact, the average person sheds more than 8 pounds of skin a year!
The fat molecules in goat milk moisturize the skin by penetrating deeply and filling in the “cracks” along the way which effectively “seals” the water in. The proteins in goat milk (amino acids) act as humectants – which attract water molecules to themselves like magnets attract iron. The actions of both proteins and fats in goat milk complement each other to dynamically hydrate and moisturize the skin.
Goat milk helps to repair skin damage, maintain healthy skin, and reduce wrinkles. Its vitamins A and E help to rejuvenate the skin through the promotion of epidermal differentiation. What is epidermal differentiation? In short it’s the process of skin renewal. Skin cells are constantly being created at the base of the epidermis. Once new cells have been created they begin their pilgrimage to the outermost surface of your skin. Along the way they undergo several changes and perform different functions before they finally die and flake off.
