This could have positive effects on skin hydration and moisturization, as well as its defense against external aggressors such as bacteria, irritants and pollution.
JD Jojoba Oil's impact on the skin barrier and moisture retention was investigated in 22 female panelists (average age 50) with normal and dry skin types. Subjects underwent 28 days of twice a day application of the oil as a moisturizer. Measurement were then taken on the face for the long-term impacts and the forearm for short-term results.
The results purportedly showed that JD Jojoba Oil decreased the TEWL (transepidermal water loss) within 24 hours after application and reinforced the hydro-lipid barrier after 14 and 28 days.
The company also aimed to prove the moisturization effect attributed to JD Jojoba Oil. An in-vivo study was conducted to define the direct influence of the oil on the level of skin moisturizing for the short term.
The results reportedly showed that JD Jojoba Oil had a notable short-term moisturizing effect, increasing hydration by 30% within the first half hour after application.
“The studies’ conclusions prove what we have known for generations: jojoba oil, whether in formulation or applying it directly on the skin in its pure form, provides both short-term and long-term moisturization and protective benefits,” said Lee Reuveni, CEO, Jojoba Desert. “The benefits of JD Jojoba Oil have a cumulative effect: the more it is used over time, the skin will become healthier and achieve a long-lasting glow.”
