The Functions of Oil Serum
Of the many facial serums, the oil serum is the easiest to make. It typically has a foundation of exclusively high-end carrier oils, and these high end oils mixed with the serum provides both moisturizing and barrier repair properties, and it can also provide polyphenols, needed fatty acids and other nutrients that are essential to the skin.
On top of the main ingredient, there is also a high performance oil-soluble extract that can have a significant effect on the skin, as well as aroma-blends that possess aromatic chemicals that can help the skin. A serum will give you the most moisturizing and barrier strengthening properties to the skin, including antioxidant properties.
