Carrier oils are naturally derived from vegetarian sources and have a neutral smell.
They aren't volatile like essential oils, which makes them an excellent medium for dilution and application for especially strong essential oils, reducing the concentration of the essential oil without altering its therapeutic qualities.
The witch hazel plant, from which witch hazel extract is derived, is a small shrub that is indigenous to North America and grows naturally across Canada and the USA. Native Americans have long used witch hazel extract for medicinal purposes.
The leaves and bark from the witch hazel plant are high in tannins, a natural astringent, that can dry and tighten skin tissue, tighten pores and remove excess oil. Its ability to fight bacteria further helps maintain clear skin. Rich in antioxidants (thanks to the tannins), witch hazel can limit the production of free radicals, which are known to damage the skin. Combined, these properties work to give your skin a youthful looking glow. Witch hazel astringent, anti-irritant, and surface numbing properties allow it to pull the irritation out of insect bites, sunburns, sore muscles, and more. With soothing and anti-inflammatory properties, it has long been used to reduce swelling and help repair broken skin.
