Jojoba oil is the liquid produced in the seed of the Simmondsia chinensis plant, a shrub, which is native to southern Arizona, southern California, and northwestern Mexico. The oil makes up approximately 50% of the jojoba seed by weight.

DESCRIPTION

shelf-stable when compared with other vegetable oils mainly because it contains few triglycerides, unlike most other vegetable oils such as grape seed oil and coconut oil.It has an oxidative stability index of approximately 60,which means that it is more shelf-stable than safflower oil, canola oil, almond oil or squalene but less than castor oil and coconut oil.

COMPOSITION

You need to make sure that what you’re buying is 100% first-pressed expeller-pressed (or “cold pressed”) organic jojoba oil. This is often labeled ‘unrefined’. It must be organic.

It may seem counterintuitive to smear oil on your face, especially if you’re prone to breakouts, but jojoba might actually make greasy skin better. Jojoba oil moisturizes skin all day, so it’s ideal for dry faces, too. Jojoba is very mild, and you can apply it directly to your face.

Add three to five drops to your conditioner or apply one to two drops to damp hair after showering. Use one to three drops of jojoba oil and apply it to wrinkled areas, then rub it into your skin in a circular motion until it’s absorbed. Add three to five drops of jojoba oil to a cotton ball or pad and wipe off makeup.

BENEFITS

It’s moisturizing – Jojoba oil is a humectant ingredient. This means that it works to seal your skin with a protective barrier to keep it from losing moisture. This may help prevent bacterial infections, acne, and dandruff from forming.

It’s antibacterial – Jojoba oil contains antimicrobial and antifungal properties. While lab tests found that jojoba oil doesn’t kill all bacterial or fungal species, it does kill certain bacteria and fungi that can cause salmonella, an E. coli infection, and candida.

It’s an antioxidant – Jojoba oil contains natural forms of vitamin E. This vitamin works with your skin as an antioxidant. This means that jojoba oil can help your skin fight oxidative stress caused by everyday exposure to pollutants and other toxins.

It’s noncomedogenic – Although jojoba oil is a botanical substance, its makeup is so similar to the oil (sebum) your body naturally produces that your skin can’t tell the difference. This makes it less likely to build up on your skin and clog your pores, leading to fewer breakouts and less severe acne.

It’s hypoallergenic – On a molecular level, jojoba oil is a wax. Although it can be absorbed into your skin, its waxy nature allows it to create a soothing seal on the surface. Unlike other botanical essential oils, jojoba oil is typically nonirritating. Allergic reaction is rare.

It helps control sebum production – Jojoba oil regulates sebum production because it’s so similar to the sebum that your body produces naturally.
