What is jojoba oil face oil ?
Jojoba Oil Face oil is the extract of Jojoba, a native Mexican plant, which has the effects of moistening, tightening skin, softening fat and diminishing inflammation. It is not oil, but liquid wax, which will solidify at low temperature. Strictly speaking. jojoba oil face oil is the most permeable base oil, easily absorbed by the skin, refreshing, moist and non-greasy, which can restore the H balance of the skin, remove wrinkles, effectively improve oily skin, regulate the secretion function of sebaceous glands, shrink pores, and is also the best skin moisturizing oil. The oil film formed by it is different from mineral oil, which can penetrate the evaporated water and control the loss of water. A good product is golden yellow, very clear, smells a little nutty and full, but it won't be greasy and heavy like other vegetable oils. It will be absorbed at once if it is slightly touched on the skin.

How is jojoba oil face oil extracted?
jojoba oil face oil requires pretreatment of jojoba seeds, including cleaning and impurity removal, crushing and rolling, steaming and drying. The cleaned Jojoba seeds are sent to a crusher to reduce its particle size, increase its specific surface area and rupture some cell membranes. Rolling can be done after crushing or directly without crushing.
Rolling can not only destroy the seed tissue mechanically, but also shorten the mutual diffusion distance between solvent and oil during extraction, and reduce the internal resistance of seed slices to the diffusion of solvent and oil molecules. Steam drying can improve the permeability of cell membranes that have not been damaged during the crushing process of rolled sheets through the action of water vapor and temperature.
The tiny oil droplets that were emulsified by protein but not dispersed in the seeds were steamed and dried, and the protein was denatured and solidified by heat, which destroyed the emulsified state and made it easier for the small oil droplets to gather. The larger oil droplets of jojoba oil face oil were separated from the seeds.
Steam drying makes water combine on the surface of solid matter to replace part of oil, and produces considerable hydrophobicity, which reduces the affinity between oil and the surface of solid matter in seeds. This effect can improve the oil yield during pressing.
The temperature of steaming and drying is generally 105 ~ 120℃, and the time is 80 ~ 120 min. It is better to control the moisture content of the seeds after steaming and drying at 2% ~ 5%. The seed material used for extraction need not be steamed.
The extraction and separation of oil includes three methods: pressing, solvent extraction and supercritical CO2 extraction.
What are the effects and functions of jojoba oil face oil ?
jojoba oil face oil is a natural vegetable oil extracted from the seeds of Simondwood plant, which is often used in the field of skin care and hair care. Its efficacy and function mainly include moisturizing and nourishing, antioxidant protection, regulating oil secretion, soothing skin and promoting ingredient absorption.
1. Moisturize and nourish
Its molecular structure is similar to human sebum, which can quickly penetrate into the skin surface and form a water-locking film to reduce water loss. This characteristic makes it an effective natural moisturizer, especially suitable for dry or sensitive skin.
2. Antioxidant protection
jojoba oil face oil contains natural vitamin E and polyphenols, which can neutralize the oxidative damage of free radicals to the skin. Long-term use is helpful to delay the skin aging process and enhance the skin's defense ability against external environmental stimuli.
3. Regulate oil secretion
Although it belongs to oil substances, it has a two-way adjustment function. For oily skin, it can help soften keratin, dredge pores and reduce the accumulation of excess oil; For dry skin, necessary lipids can be supplemented to maintain water-oil balance.
4. soothe the skin
jojoba oil face oil contains linoleic acid and linolenic acid with anti-inflammatory properties, which can relieve discomfort such as redness and itching caused by environmental stimulation or slight skin problems, and is often used for post-sun repair or sensitive muscle care.
5, promote the absorption of ingredients
As a good carrier oil, its small molecular characteristics help other active ingredients penetrate the skin. When used with essential oil or functional skin care products, it can improve the overall skin care effect.
It should be noted that although Jojoba Oil Face oil has multiple skin care functions, it is recommended to have a local skin test before use. People with different skin types should adjust the frequency and dosage according to their own conditions, and pay attention to the compatibility of ingredients when using with other skin care products.
